Detailed Description
Description:
•Feed air compression, pre-cooling and purification systems
Feed air from atmosphere is removed dust and mechanical impurity through air filter then enters into Air Compressor. Compressed air with pressure of 0.7Mpa(G) is sent into Air Pre-cooling System to be cooled down to 5~8°C.
Cooled air enters into Molecular Sieve Purification System for adsorption in where moistures, carbon dioxide, acetylene and other hydrocarbons impurities are removed. There are two alternative working vertical adsorbers. When one adsorber works another will be in regeneration.
•Air rectification
Purified air with temperature of 10~16°Cfrom Molecular Sieve Purification System is sent into Main Heat-exchanger in where the purified air is cooled down by reflux cryogenic flow to saturation then goes into rectification column.
The liquid air we got in the bottom of column is sent to condensor-vaporizer on the top of column as condensate liquid after throttling. The oxygen riched liquid air in the condenser -vaporizer is sent to main heat exchanger and rewarm up tp -152°C and then goes into turbo expander for expansion. The oxygen riched air return back to the cold end of heat exchanger after expansion, in there oxygen riched air are rewarmed to normal atmospheric temperature and then goes out of cold box. They will be used as regeneration gas and other superlus will be vent.
The product nitrogen drawn out from the top of column to heat exchanger for rewarming and then send out of cold box to nitrogen consumer.
