Cleaning Procedures for Oxygen Service Based on Application

Category Field Application Recommended Cleaning
A Construction sites within which Air Separation Unit (ASU) equipment is being made and/or installed. For carbon steel with rust or scale, sandblasting to a white metal surface is the method of choice. For other materials, hot water/steam (aqueous) detergent cleaning is preferred. Rinsing of residual aqueous cleaning agents is especially of import, every bit the detergent residues are not oxygen compatible. Availability of utilities/water, electric ability, and heated enclosures are of import. Due to the need to prevent unauthorized use, other cleaning methods/agents that require special precautions and training (for example, ensuring removal from equipment, express personal exposure, flammability) are generally not suitable for employ at these sites.
B Stationary plant equipment, including pipe, vessels, and cylinders. Generally involves big scale components and must exist done on-site. Hot water/steam detergent cleaning is preferred. Availability of utilities/water, electrical power, and heated enclosures are important. Flammable (HVP) solvents may exist used in small quantities.
C Field installations, including client stations piping and components. Generally, cleaning is done on a minor scale in an open up area. HVP solvents in pocket-sized quantities are adequate because of a lack of a practical alternative. Utilities are not available, see section 5.3.
D Large equipment fabrication facilities, including cryomachinery and vessel/column manufacturing. Hot water/steam detergent cleaning is advisable for large parts. Submersion in agitated baths (for example, ultrasonic) enhances cleaning. Caustic and acrid-based cleaning might be appropriate provided that corrosion issues are adequately addressed. HVP solvents may be used in small amounts.
East Modest equipment fabricators, including musical instrument shops and laboratory scale equipment. HVP solvents are preferred, see department 5.3.
F Minor equipment fabricators, including instrument shops and laboratory scale equipment. Stock-still detergent systems such every bit 'washing machines' or HVP solvents are preferred.
G Oil removal from contaminated ASU equipment (plant washout). Less complex systems such as brazed matrix Al or SS exchangers, liquefiers, main exchangers may be suitable for aqueous washing. Methylene chloride in a closed (recovery) system is preferred for difficult zones such as columns where dryout is a problem, see section v.3.

Cleaning Agents for Oxygen Service

Material Application
TICKET Small components in workshop weather
Methylene chloride Small scale cleaning of Tubes/Fittings/Equipment
Methylene Chloride Complex Plant washouts
ISOPROPANOL (Rocol Industrial cleaner rapid drying Spray) TDE (transdichloroethylene) Run into paragraphs 5.2 through v.2.1.5. Spot cleaning of accessible surfaces.
(Vertrel, Contact cleaner G3, 3M's HFE-71DE) Small scale cleaning of Tubes, fittings, equipment.
1.1 Dichloro-1-Fluoroethane (H141b) (Genesolv 2004) Spray cans only. Minor components and tubing.
2-(two-butoxyethoxy) ethanol) (Blueish Golden (A), Simple Green (A)) All applications where detergent methods are acceptable
Beyond 2001 (A)
Safezone solvent flux remover Spray cans only. Small-scale components and tubing.
Safezone precision cleaning solvent Spray cans only. Small-scale components and tubing.
Tramos Small scale cleaning of Tubes, fittings, equipment.
Pyrene 1027 (A) [Oakite Products,Inc] Small calibration cleaning of Tubes
Clear Clean (A) [Classic Chemicals, Inc] Small scale cleaning of Tubes
eOx cleaner Small scale cleaning of Tubes, fittings, equipment.

Note:'pocket-sized calibration' is a judgment simply refers for instance to cleaning of a small-scale number of tubes or equipment where larger stock-still cleaning equipment is not practical to use, so for example emergency repairs or customer site maintenance.

Cleaning Agents Not Useful for Oxygen Service

Material Awarding
P3 GLIN Any (due to leaving residue)
AMBERCLEAN FE10 Any (due to leaving residuum)
ROCOL U/C 2000 Whatever (due to flammability concerns)
MICRO Any (due to ineffectiveness)
ISOPROPANOL (Rocol Industrial cleaner rapid drying Spray) Whatever except for Spot cleaning of accessible surfaces. See paragraphs 5.2 through 5.2.1.v. (due to flammability concerns)
SONOCLOR Any (due to environmental and health effects)
north-propyl bromide (Ensolv, Swansolv, HFE 7100) Whatsoever (due to environmental and health effects)
