Side column cryogenic rectification system for producing lower purity
oxygen
摘要:
A cryogenic rectification system employing a double column and an auxiliary side column in which product lower purity oxygen is produced wherein the side column is driven by condensing compressed feed air enabling the system to operate with lower head pressure and thus lower operating costs.
