Abstract

A cryogenic air rectification system comprising a high pressure column, a low pressure column and an argon removal unit coupled to a condenser evaporator, wherein the system is configured to pass gas from a position above an oxygen section of the low pressure column as an argon removal feed gas to a lower region of the argon removal unit, wherein the system is configured to condense gas from an upper region of the argon removal unit in the condenser evaporator to form a condensate, wherein the system is configured to pass further gas from the top of the upper region of the argon removal unit out of the system, and wherein the system is configured to pass at least a part of the condensate as a reflux to the upper region of the argon removal unit.
