Description:
The proposed plant employs a process in which air is purified by
molecular sieve and refrigerated by boosting turbine expander;
fractionating column is convection sieve trays column. The feed air
is cleaned of dust and mechanical impurities in air filter AF and
compressed to a certain pressure by air compressor. The compressed
air goes into air pre-cooling system for being cooled to saturated
state, and then goes into switchover molecular sieve adsorber MS
where the impurities such as moisture, CO2 and C2H2 are adsorbed.
The purified air is divided into three streams: one stream is drawn
out to be instrument air; the second stream enters main heat
exchanger to be cooled to the saturated temperature by refluxed gas
and then goes into the lower column; the remainder similar with
swelling capacity goes into booster to be boosted, and then goes
into main heat exchanger after being cooled, then it is drawn out
of the middle portion to expander, the expanded air goes into lower
column. After preliminary rectification in lower column, the liquid
air is obtained at the bottom of lower column and the liquid
nitrogen is obtained at the top. Liquid air and liquid nitrogen
drawn from lower column go into liquid air/liquid nitrogen
sub-cooler to be sub-cooled and then it goes into relevant position
of upper column. Following further rectification, obtain liquid
oxygen. The waste nitrogen gas drawn from the top of upper column
which is re-warmed in sub-cooler and main heat exchanger goes out
of cold box, and it is discharged after meeting the need as the gas
for regeneration of molecular sieve first.
