CLEANING OF EQUIPMENT FOR OXYGEN SERVICE - AIGA

AIGA 012/04
Emulsified oil can be removed by ultra filtration, chemical decomposition, micro filtration, and
adsorption or biological treatment. Evaporators and vapour compression apparatus are also used.
5.3 Vapour Emission Control
The control of vapour emission from solvent based cleaning equipment is essential from an
environmental as well as safety viewpoint.
In carbon or molecular sieve adsorption equipment, he vapour in the vent air is trapped in adsorption
beds. When the beds are saturated, they are regenerated by steam or hot gas.
Cryogenic condensation can also be applied, atone or in combination with carbon filter. The solvent is
condensed from the vent air in a heat exchanger cooled with liquid nitrogen.
