摘要
The argon recovery obtainable from a dual pressure cryogenic air distillation plant for production of high purity oxygen is increased beyond present levels without offsetting incurrence of detriments such as lower O2 pressure, lower O2 or N2 recovery, less liquid recovery, or increased energy. This is done by providing an intermediate reflux condenser (component 8 of FIG. 1) in the argon sidearm 2b, and providing liquid N2 via valve 9 to said condenser, thereby increasing the reboil up both argon stripper 2a and the lower section of 2b proportional to the amount of LN2 evaporated in 8.
