ProSolv®5408e vapour degreasing solvent cleaner for flushing refrigeration pipeline systems

cleaning solvent for flushing refrigeration pipeline systems

Vapour degreasing solvent cleaner for flushing refrigeration pipeline systems

Concerns connected with the challenging environmental profile of traditional refrigerant gases have led to changes in legislation which are a driving factor in phase-outs and bans on the use of some gases to remove the older materials typically with high ozone depletion (ODP) and global warming potential (GWP).  Systems can be replaced or refurbished with new models using compressors able to use more sustainable and acceptable gases. The evolving trend to newer refrigerants continues as the chemistries develop. The refrigerant R-22, which itself was an improvement over earlier refrigerants, is phased out and replaced with R-410a and other alternatives based on HFOs are being marketed.

Retrofitting of current refrigeration systems to accommodate the new developments is not straightforward as most refrigerant gases are not cross-compatible, so the necessity to completely remove all traces of the older versions from the system, including refrigerant lines is essential.

Of course, where possible it’s best simply to replace existing lines with new ones. However, it’s not always possible to do this cost-effectively, especially when the old piping runs under floors or through walls. In such cases thoroughly flushing existing pipework is especially important because even tiny traces of impurities left in the lines can damage new equipment and lead to compressor failure.

THE PERFECT SOLVENT FOR FLUSH CLEANING REFRIGERATION PIPEWORK

Your first step to proper pipework flushing is to select the right solvent. The solvent you choose must be highly effective at dissolving oil grease and other contaminants, to ensure that all residue is removed from the pipes and must be sustainable, environmentally friendly and comply with current legislation.

ProSolv 5408e is the ideal solution to this problem with a profile of properties and advantages making it perfect as your solvent of choice for refrigerant pipeline flushing.

No flash point Non flammable liquid.
High specific gravity gives a high soil suspension loading.
High solvency strength with a KB value of 98.
Powerful cleaning agent that can flush lines fast, dissolving oil and grease releasing soils from the inner surfaces of pipelines and fittings
Volatile for fast evaporation. Removing ALL solvent from the pipework after flushing is vital, very volatile so evaporates fast.
Environmentally responsible. ProSolv 5408e is sustainable and kind to the environment with very low global warming potential, zero ozone depleting potential (ODP).
Safe for operators when user conditions are followed.
Economical as it is easily distilled for reuse. No testing or stabilisation required.

PROCEDURE FOR FLUSH CLEANING REFRIGERANT PIPELINES WITH ProSolv®5408e

Of course, simply replacing old piping is the only way to be 100 percent sure that your lines are clean. But in retrofit situations where complete replacement is not possible, flushing the lines with ProSolv 5408e solvent is the best alternative solution for the protection and long working life of your refrigeration system upgrade.

1 – Remove any obstacles. Any equipment and components such as valve, filters and expansion valves that might obstruct the line should be removed prior to the purge.
2 – Pre-flush. This will dislodge any loose debris from the sides of the lines enabling more effective use of the solvent, oil free air or nitrogen at 120 psi is recommended. It’s also good practice to oscillate the pressure to encourage dislodging of debris.
3 – Preparing the pipework. Reducing the length of piping can be more effective due to the pressure loss in long lengths. Section the operation into 15 metre lengths by cutting pipes where necessary. One end of the pipe must be fitted with a connector for the pipe to the nitrogen supply while the exit needs a restrictor valve to allow variable pressures to shock loose particles from internal walls.
IMPORTANT – Flushing with solvent. Refer to ProSolv 5408e Safety Data Sheets for advice on operator protection using solvents.
4 – Safe working. Full PPE with suitable eye protection goggles and gloves must be worn. Solvent fumes are heavier than air and exposure levels can easily be reached working in pits or enclosed spaces. Always institute a ‘buddy system’ and use air fed face masks with attached line.
5 – Delivering solvent. Use a drum pump electric or hand operated with a flexible tube connection for delivering the solvent to the open end of the pipe or tubing to flush the internal surfaces. Using a fresh drum of ProSolv®5408e connect drum pump and the delivery tube to the end of pipe/tube to be cleaned using a pre-fitted screwed or compression fitting.
6 – Drainage and Testing. The drainage end of the pipe or tube should be fitted with a flexible tube into a tank or drain sump allowing samples to be taken in a glass bottle or tube at regular intervals to be sure when no particles or soils are being expelled. The colour of the solvent will change as oil and soluble contaminants are removed and flushing must continue until the flow is totally clear and water white.
7 – Post-flush. ProSolv 5408e solvent is volatile so will dry completely using an oil free airline or nitrogen supply connected to the end of the cleaned pipe/tubing.
8 – A wipe of the pipe/tubing surface at the inlet and outlet using solvent saturated lint free cloth completes the cleaning. If not connected immediately to other parts of the system enclose both ends of cleaned item to prevent recontamination.

Used ProSolv 5408e should not be reused for flushing but can be recovered for reuse by a simple distillation process. Removal from site should use licensed disposal companies.

Eliminate bad smells using unique concentrated water based cleaning system

Eliminate bad smells

Aquus® CL-One is the ALL purpose concentrated cleaning system based on an innovative formulation of surfactants which also controls odours and will eliminate bad smells at source.

The unique combination of properties exhibited by Aquus CL-One offers excellent emulsion-breaking capability in addition to its unusual combination of properties that makes it so attractive for a wide range of industrial applications including an unusual application which is discussed below in more detail, utilising these properties to control odours and eliminate bad smells at source.

CONTROL ODOUR BY ELIMINATING UNPLEASANT SMELLS AT SOURCE

Aquus CL-One eliminates odour problems caused by bacteria and other organisms. No fragrance or other masking agents are used, the odour is very effectively eliminated at source. Conventional masking agents use fragrances or enzymes which act slowly and are less effective and more expensive than the Aquus CL-One alternative which uses a totally different approach to these problems.

MANY APPLICATIONS FOR ODOUR CONTROL

Odour control is needed where cleaning is performed in food preparation, processing equipment and containers, sewage treatment plants and in other waste-water facilities.

VOLATILE ORGANIC COMPOUNDS

Aquus CL-One breaks down the organic compounds responsible for the release of the volatile organic compounds (VOCs) producing the unpleasant smells associated with some commercial and industrial processes and systems.

Aquus CL-One eliminates the ability for bacteria to produce the odour producing VOCs by disrupting the integrity of the cell walls.  Odour producing microorganisms have cell walls made up of organic materials including lipids (fats). The alkalinity and surface-active ingredients of the Aquus formula breaks down the cell walls of the organism which protect the inner workings. Once compromised the bacteria can no longer absorb nutrients and eliminate waste. This kills the organism which then cannot generate the VOCs which produce the smells.

ADVANTAGES OVER OTHER METHODS

Aquus CL-One has considerable advantages over the toxic, fragrance or enzyme based alternative odour control products which only mask the smells. Enzyme based formulas need regular maintenance to keep the enzymes active and work slowly. Masking agents are usually ineffective and expensive.

Aquus CL-One eliminates completely the odours and smells associated with these organic materials including bacteria and other organisms simply and effectively.

Some examples of controlling bacteria related odours –

ENGINEERING WASTEWATER TREATMENT SYSTEMS

Aquus CL-One is extremely effective in separating oil, water, and solids in drains, conveyor traps and sumps on automatic honing, turning and grinding machines when using water-based lubricant and cooling liquids.

Emulsions are broken allowing cleaned metal dust, shavings and dirt to precipitate to the bottom, the solution of Aquus CL-One and water retains the active cleaner in the middle layer, oil and grease float to the top. The efficiency of oil/water separators in plant waste treatment systems are significantly increased while the disposal of toxic waste is greatly reduced.

FARMING AND AGRICULTURE   

FARMING AND AGRICULTURE    Farming and agriculture require reliable water-based cleaners for the innumerable cleaning applications needed particularly where animal husbandry is involved. Scrupulous cleaning of surfaces on rails, floors and walls is essential for the health of the animals. The unique bacterial destruction abilities described earlier is very effective in odour control in many farming applications

Aquus CL-One is the concentrated water activated cleaner which is used at different dilutions to meet the requirements of the many applications and challenges met in farming and agriculture. Aquus CL-One which is completely biodegradable within 30/40 days, is not toxic and not considered a hazard which is particularly important in sensitive environmental sites and situations. Safe for use with any application equipment such as high or low-pressure washers, spray washers or dip tanks it can be used with mops, brooms etc by operators without needing personal protective clothing.

The unique combination of oleophilic and hydrophilic properties encourage sedimentation of solids from liquids in wastewater separation tanks and as the cleaner solution can be recycled and reused until biodegradability reduces its effectiveness it is very economical in use. As an example, in normal use a one litre bottle is mixed with 40 litres of water to activate the cleaning solution which in turn can be recycled many times.

HOSPITALS AND HEALTHCARE  

HOSPITALS AND HEALTHCARE   Cleaning of soiled and contaminated surfaces in hospitals, nursing homes and other medical facilities is essential to control bacterial contamination. Aquus CL-One cleaner can be used for all cleaning applications which reduces time and costs by removing the need for multiple cleaning products usually needed to deal with the challenges presented by the wide range of soils, oils, blood, body liquids and other contaminants which need to be removed.

Aquus CL-One is safe for the environment and users, contains no solvents and is biodegradable within 30 days. With only one product for all cleaning applications incorrect selection or dangerous uses can be avoided.

Vapour degreasing – A simple guide for production engineers

vapour degreasing

This simple guide for production engineers discusses why vapour degreasing is the most effective and economical process for cleaning of manufactured components.

Now is a good time to review your existing cleaning processes or upgrade current equipment. In the autumn Budget 2021, the Chancellor, Rishi Sunak, announced an extension of the temporary increase in Capital allowances which allow the cost of capital assets to be written off against taxable income. The 130% super-deduction and 50% first-year allowance are very generous but only available for a short time. This will allow companies to not only lower their corporation tax bills but improve productivity and reduce operating costs for cleaning processes.Vapour degreasing is the simplest but most effective degreasing and cleaning process which, until recently, has been subject to little change since it was first invented in the early part of the last century. This is a very mature chemical technology which legislation is now effecting changes so fundamental that the more accurate name for the process “Condensation Cleaning” should be used to reflect the improvements in equipment design, chemistry, reduced emissions, economies in usage of solvents and the subsequent environmental acceptability compared to the open topped tanks so ubiquitous in factories and workshops worldwide. The alternatives in equipment design offer differences in technology, which guarantee the continuing use of this process in the future, need to be considered and understood.

cleaning tank The cleaning tank in the corner of most engineering shops hides a very well researched process using sophisticated chemistry. Its popularity is in its simplicity. The tank sump is heated, fitted with cold coils around the internal surfaces at the top to retain the vapour.  Fill to a few centimetres with a non-flammable solvent able to dissolve contaminants, boil to form a vapour 3 to 4 times heavier than air to fill the tank. Hot solvent vapour condenses on the cooler target parts at workplace temperature. The hot liquid solvent dissolves oil and grease and other contaminants. Used solvent returned to the sump revaporises continuing the cycle until parts have achieved the same temperature as the vapour when, with no further condensation, the process is complete. Simple but perfect. Highly productive and economical, parts removed from the cleaning process are clean, warm, and dry in 5 to 10 minutes.

Historically chlorinated hydrocarbons have been the solvents of choice for the “Condensation Cleaning” process. Compatible with most materials of manufacture, stable in constant use, producing a non-flammable saturated vapour heavier than air at a temperature greater than ambient.

In Europe, the United States and in other advanced industrialised economies increasingly stringent legislation to control emissions of VOCs, especially solvents, has led to new formulations for paints and other coatings where water replaces most of the solvent. In the early days the quality of water-based paints was not as good as traditional solvent-based coatings, but innovation has driven the development of new polymers with results as good as, if not better than, the solvent-based originals.

As with coatings, cleaning systems have had to change. With increasingly demanding standards of cleaning required for precision engineering, electronics, optics etc solvents are often first choice, for reasons outlined above, but these have been targeted by regulators and alternatives are encouraged by the relevant authorities and law makers often without serious consideration of unintended consequences.

For example, water-based cleaning is encouraged as the obvious alternative, but this has many disadvantages compared to condensation cleaning as although the machines are simple and relatively cheap the processes require multiple heated tanks for immersion or spray processing or long programmed cycles in batch machines for cleaning, rinsing, and drying. Water based processes are slow, energy intensive and occupy more floor space than solvent-based condensation cleaning equivalents where only one tank with a small footprint is needed, delivering shorter process times and, most importantly for the environment, using minimal energy.

The ideal cleaning process would be “Condensation Cleaning” using water but due to the physical characteristics of the water vapour/steam and the inability to carry onto the surface of the targeted parts surfactants to remove the oil, grease and soils and the difficulty and expense of rinsing and especially drying this can only ever be a dream.

Historically chlorinated hydrocarbons have been the solvents of choice for the “Condensation Cleaning” process. Compatible with most materials of manufacture, stable in constant use, producing a non-flammable saturated vapour three to four heavier than air at a temperature greater than ambient.

The traditional solvents such as trichloroethylene exhibits all these characteristics however concerns about its carcinogenic properties and the danger to operators by exposure, led to a continuing search for a safer alternative. 1,1,1 trichloroethane based solvent formulations became popular in the mid part of the last century as a safer replacement. An excellent solvent, safer for users, it proved to be depleting the protective ozone layer around the Earth and was subsequently banned. With the development of the REACH legislation in Europe, trichloroethylene was again allowed with restrictions and stringent controls for use in authorised machines which control emissions to very low figures close to zero.

EnviroTech have been supplying vapour degreasing solvent formulations for 40 years constantly responding to increasingly stringent regulatory requirements for environmental and safety laws and the need for improved cleaning standards.

ProSolv® 5408e is a new sustainable solvent blend with near zero OPD (Ozone Depletion Potential) and GWP (Global Warming Potential) for high performance degreasing and cleaning which ticks all the boxes with the perfect profile for a vapour degreasing solvent. Soft on the environment and safer for users with high performance, improved cleaning, and lower costs. Lower boiling point, economical with energy with low solvent losses, faster production, reduced costs, easy handling. Exceptionally low surface tension to penetrate micron sized holes and close contact surfaces. Sustainable and secure for future use as your ‘forever solvent’.

As with all legislation for chemical use regulation and restrictions drive development of associated processes and equipment. Sealed tanks are now standard with many different designs available. The most common are discussed below.

The single tank hermetically sealed machines favoured by some manufacturers uses a process tank to contain the solvent and a separate storage tank/vapour generator. Baskets loaded with parts to be cleaned are introduced from the top or through access points on the side of the tank. Lids or doors hermetically seal the tank. Solvent is pumped into the process tank where agitation, ultrasonics or pumped liquid is circulated through the parts. Used Solvent is removed to the vapour generator, condensing coils controlling the vapour are linked to coils located in the vapour zone which, when the cycle is complete, collapse the vapour.  The process tank is emptied. Controlled air introduced to process tank is then recycled through carbon absorption units to remove traces of solvent until the concentration is within regulatory standards when the lid is released for the basket of parts, clean and dry, to be removed and replaced with a further basket.

Variations of process within the hermetically sealed tank are possible using sprays of cold or hot condensed solvent, immersion with or without ultrasonics and revolving baskets to cover most of the problems experienced when processing machined and fabricated parts. Continuous external distillation of the contents of the vapour generator is also an option depending on contamination.

The alternative technology is much simpler and uses well tried techniques not requiring the long recovery times of the hermetically vacuum sealed processes. The multilevel system uses a standard vapour degreasing tank design with a sealed loading section above the process tank. Components to be cleaned loaded in work baskets or jigs are fed to the load section by hand or conveyor, an internal platform raises and lowers the baskets in controlled cycles.

Loading complete – the load enclosure is sealed to completely isolate the process. Then seal on the process tank is opened and the basket automatically lowered into the cleaning section which can be simple condensation cleaning or immersion cleaning with or without ultrasonics or power sprays. Revolving baskets can also be added to improve cleaning in blind or through holes or oil ways in castings and fabrications.

On completion the basket rises to the area where the condensation coils are located, and parts allowed to drain and dry, basket raises into the load section when the process tank is sealed. A fan circulates air within the load area which can be recycled through carbon absorption systems if no external exhaust is preferred.

As baskets entering the loading space contain parts drained and dried only very small amounts of solvent are carried in the exhausted air which is monitored to ensure compliance with appropriate legislation. When this is complete the seal opens fully for removal of cleaned components. The loading section can be fitted with top or side seals allowing baskets to flow through on conveyor systems or be removed by hand or hoist. No solvent enters the work area.

Both processes will produce parts cleaned to the highest standards but the choice of which offers the best solution needs a little more consideration.

The hermetically sealed vacuum process is complicated with the need to move liquids in the machine. It is relatively slow as the carbon adsorption process has to remove high levels of solvent from the recirculated airstream from the process tank. This is inefficient as adsorption rates for carbon fall rapidly with increasing saturation.  Final levels of solvent in the tank when the lid or loading door opens will be dragged into the workshop and the area where the operator is working. Long process cycles reduce throughput.

The simpler multilevel systems where movement of liquids is not required are more efficient and offer much faster process times.  Cost of manufacture is also reduced as no liquid movement or vacuum is involved. The extracted loading section ensures no leakage of solvent into the work area giving complete safety for operators and factory staff.

Both designs of process machines fully comply with the emission regulations of the EU and U.S authorities. Which to choose will depend on many factors which should be discussed with equipment and solvent suppliers who have the experience to advise on which offers the best process for the application. Equipment and solvent must work together, so it is advisable to ensure that the suppliers co-operate to offer a package with high levels of responsible care and product stewardship to ensure the best and safest installation. EnviroTech personnel and distributors are trained to work with our equipment suppliers to advise on the use of ProSolv® 5408e for the most satisfactory outcome.

Condensation cleaningThe “Condensation cleaning” process still gives the highest levels of economical cleaning with minimum energy usage, low footprint on the factory floor, safety for the operator, and high production rates with low solvent usage and environmental impact. With the new generation of sealed cleaning machines its future as the process of choice is assured.

SuperCORR A -Advanced corrosion protection for aircraft

corrosion protection for

Advanced corrosion protection for aircraft – SuperCORR A lubricates and protects mechanical and electrical flight controls in surveillance aircraft.

Super CORR A provides advanced corrosion protection for aircraft – It lubricates and protects mechanical and electrical flight controls and electronic equipment in Lockheed Martin P-3C Orion aircraft flown by air forces around the world for anti-submarine and maritime surveillance, also used in searches for missing ships or aircraft.

The Royal Australian, Korean and Japanese Air Forces were employed in the search for the Malaysia Airlines flight MH370 Boeing 777 passenger jet which disappeared on a scheduled flight in March 2014. The search for debris in a vast area of ocean, bigger than the land area of Europe, southwest of Perth, Australia operated for thousands of hours at low levels but failed to locate any debris and was suspended in 2017.

The maintenance schedules specify Super CORR A to lubricate and protect the flap tracks and screw jacks in the wings of the aircraft which are constantly exposed to extremely corrosive salt laden air as the aircraft in search mode can be flown at very low altitudes of hundreds of feet for long periods.

Super CORR A lubricant and protective coating is widely used by the military, electrical, electronics and aerospace industries for critical applications to give the protection needed in extreme conditions. Super CORR A deposits a dry protective film with excellent corrosion protection and lubricant properties plus the added advantage of a hydrophobic surface rejecting water that ensures the easiest and best connections for very close spaced connectors, contacts, wiring and moving parts

The U.S. Navy selected Super CORR A after exhaustive testing using American Society for Testing and Materials (ASTM) Standard B117- Standard Practice for Operating Salt Spray Apparatus.

Super CORR A, a Type I, Grade B Corrosion Preventative lubricant out-performed 11 other products in comparative testing to identify the best product to protect and lubricate the flap tracks and screw jacks on the aircraft.

The flap tracks, located in the aircraft’s wings, are what the flaps slide on when they move up or down to lower or increase speed. The screw jacks engage and retract the wing flaps. Corrosion on any of the surfaces can lead to snatching or vibration which can affect the pilot’s control

Due to constant operation in salty and corrosive atmospheres which need post-flight rinses and monthly washing down of the aircraft re-lubrication and corrosion treatment for the flap tracks and screw jacks is required each time, with conventional lubricants, to prevent rusting.  Super CORR A was evaluated against competitive products under the Federal Test Method Standard #791B, using a five percent Salt Spray Corrosion Test.

Super CORR A far exceeded the performance of the other products evaluated.  After over 200 hours of continuous exposure to salt spray corrosion, Super CORR A protection actually increased over time where all the other, similar, products failed early or contributed to an increase in corrosion.

The accelerated salt fog corrosion testing demonstrated that the application of
Super CORR A which complies with MIL-DTL-87177B (revised MIL-L-87177A) also increased electrical operation to 1400 hours versus 100 hours for the control product used at that time. Technical manuals were updated to include the application for electrical and mechanical parts for civilian and military operations.

The most important conclusion from the historical data and prototype testing is the availability of this excellent corrosion preventive compound that has dry film lubricant properties. The application of Super CORR A on aircraft components can reduce maintenance man hours, reduce part replacement costs, increase life of aircraft, safety, and readiness for operations.

Estimates for the maintenance cost for the US Air Force F-16 fleet can reach $500 million per year, the use at all military branches could reach billions of dollars per year. Applications at locations tested by the U.S. Air Force are not normally treated with corrosion prevention and control lubricants (CPC’s). These are the electrical connectors that are susceptible to subtle and not so subtle forms of corrosion that can interfere with the electrical operation of the F-16.

Testing by the U.S. Navy at NADEP Jacksonville incorporates not only electrical connectors, but mechanical and structural components as well. Future uses will also include ground support equipment. The properties of Super CORR A are such that it can be used in a wide variety of applications and on any materials, metal or plastic. Properties of the Super CORR A far exceed the requirements defined by the MIL-L-87177A specification. Many of the beneficial properties of the product are not required in the MIL specification.

Some of the applications are discussed below.


MANUFACTURING, ENGINEERING and MAINTENANCE

Formulated to tackle the numerous cleaning applications required by the manufacturing and engineering industries. Concentrated Aquus chemistry is activated by water, varying concentration levels allows the most economical solution to be chosen for specific applications from parts cleaning to surface preparations for finishing or heavier soiling on process machines all from one product. Some of the applications are discussed below.  Our applications experts and samples of the product are available by completing the contact form.


PARTS AND COMPONENT CLEANING
Ideally suited for cleaning protective coatings, grease and soils from used or parts during manufacturing processes. Aquus CL-One can be used in parts washing equipment or dipping tanks without modifications and leaves no residue after drying.  Oil and grease separate from the water and coalesces on the surface of the cleaning solution which can then be skimmed off for recovery and recycling. Precipitated solids free of hydrocarbons can be removed by settlement or in filtration systems. The cleaning solution can be reused continuously within its chemical effectiveness parameters for efficient and economical use.


GENERAL CLEANING
Aquus CL-One is remarkably efficient removing oils, greases, and accompanying dirt from most surfaces.  It can be applied by wiping surfaces, mopping floors or in rotary floor cleaning machines, or by low or high-pressure spray. Aquus CL-One is also an effective cleaner in industrial kitchens removing grease and baked on deposits on internal surfaces of ovens and trays. For maintenance of machines, engines etc oil and grease is easily removed pre and post assembly making inspection and repair easier, quicker and cheaper by returning equipment to use.

WASTE TREATMENT SYSTEMS
Aquus CL-One is extremely effective in separating oil, water, and solids in drains and conveyor traps and sumps on automatic honing, turning and grinding machines when using water based lubricant and cooling liquids. The emulsions are broken allowing cleaned metal dust, shavings and dirt to precipitate to the bottom, the solution of Aquus CL-One and water retains the active cleaner in the middle layer, and oil and grease float to the top. The efficiency of oil/water separators in plant waste treatment systems are significantly increased while the amount of toxic waste requiring disposal after treatment is significantly reduced. The cleaning solution can be reused to treat more waste streams until biodegradation occurs and it no longer operates effectively.

COMPONENT CLEANING FOR OXYGEN SERVICE

Cleaning for oxygen service is best defined as the removal of combustible contaminants from the surface of any equipment or system in oxygen service. Essentially, any component that may encounter an oxygen rich environment.

The combustible contaminants include organic and inorganic substances such as hydrocarbon material for example oils and greases, paper, fibre, dust, and soils. If these contaminants are not removed properly, in a worst-case scenario, this can cause combustion or explosion in an oxygen atmosphere or at the least rejection of the product due to unacceptable product purity.

Oxygen is not flammable, but it supports combustion. Oxygen can react with most materials. The higher the oxygen content and/or pressure in a system the more vigorous the combustion and the lower the ignition temperature required. Materials that do not normally ignite in air will burn and may explode in an oxygen rich environment. In addition, the oxygen rich environment will give rise to a higher flame temperatures and combustion velocity with potentially devastating consequences.

The recognition of oxygen’s reactivity has led to stringent requirements regarding the cleanliness of equipment in oxygen service. Strict guidelines exist to ensure that care must be taken in the selection of equipment including all materials and components, which all need to be oxygen compatible. They must also be free from combustible contaminants as described above.

Special consideration must be given to any cleaning processes employed in the manufacture and maintenance of all components of oxygen service systems. There are many options depending on the type of contaminants from aqueous to semi aqueous and blasting systems to remove welding slag etc. These are all referenced in the publications in the addendum below and we refer particularly in this article to the European Industrial Gases Assn (EIGA) DOC 32 4.3.1.2 Solvent Cleaning.

Solvent cleaning offers huge benefits in cleaning processes. ProSolv 5408e  our NEW sustainable solvent is especially relevant for this use. Energy saving, totally recyclable, environment friendly zero ODP and GWP and safe for operators. High output, very fast process times, non-flammable, an excellent solvent for all the oils, greases and other organics which need to be removed after manufacturing processes and it is compatible with all types of metals and equipment, from immersion cleaning in simple multi tank counter current processes to integrated vapour and vapour liquid tanks with and without ultrasonics. EnviroTech Europe have extensive partnerships with equipment manufacturers through our distributors worldwide and information and advice on solvents and solvent systems and which need to be considered Some of these are discussed below.

Specific consideration must be given to the following:
· Cleaning standard to be achieved (how clean is clean?)
· Cleaning procedure
· Solvent cleaner to be used.
· Surface properties of the parts to be cleaned.
· Shape and geometry of the material
· Types and amounts of contaminants.
· The degree of automation required.

The size and capacity of the equipment is determined by:

  • The size of the material or components to be cleaned.
  • The required throughput.

Your starting point should be the cleaning standard and procedure. Solvent cleaning and solvent vapour phase cleaning of components consists of the removal of contaminants by immersion in the solvent, possibly with the addition of ultrasonic agitation and the action of continued condensation of solvent vapour on the component surfaces. The procedure requires that the oxygen equipment, system or component is colder than the solvent boiling point. This allows the vapour to condense on the components and perform a final rinse.

The major significant advantage of solvent cleaning is that vapourised solvent is always pure, and the contaminants remain in the boiling liquid section which requires only periodic cleaning out, thus causing a reduction in the frequency of system downtime.

The effectiveness of a particular cleaning agent depends upon the method by which it is used, the nature and type of the contaminants and the characteristics of the article being cleaned, such as size, shape, and material. Final evaluation of the cleaning agent should include testing of actual products and production processes.

All equipment must, together with the cleaning chemistry, comply as a minimum with current legislation for health, safety and environment. The efficiency is controlled by utilising typical samples, written procedures and requested criteria for cleanliness.

INDUSTRY STANDARDS FOR CLEANING OF EQUIPMENT AND COMPONENTS

As part of the programme of worldwide harmonisation of industry standards, the European Industrial Gases Association, (EIGA) has published EIGA Doc 33-18, Cleaning of Equipment for Oxygen Service. The publication was developed from the Compressed Gas Association Document G-4.1 Cleaning Equipment for Oxygen Service and the EIGA Document, Doc 33 Cleaning of Equipment for Oxygen Service.  For information see EIGA’s website.
