ENHANCED ARGON RECOVERY FROM INTERMEDIATE LINBOIL

摘要

the recovery of argon which can be obtained from a cryogenic air separation system with dual pressure for the production of oxygen of high purity is increased beyond current levels without the disadvantages such as low pressure o2 plus (e) recovery of o2 or n2 lower than liquid recovery.and more energy.this result is obtained by using reflux condenser (208), intermediate (208) of the component (figure 2) in the side arm of the argon (202b) and with liquid n2 via the valve (209) to the condenser.the aim is to increase the reboiler in the column for correction of argon (202a) and the lower section of the side arm of the argon (202b) in proportion to the amount of ln2 evaporated in the condenser (208).
