ABSTRACT:
A cryogenic rectification system for producing nitrogen having a low argon content wherein the reflux ratio in the upper portion of the higher pressure column of a double column system is modified by withdrawing nitrogen vapor from below the top of the column, liquefying the withdrawn vapor, and returning the liquefied nitrogen to the column at or near the withdrawal point and below the top of the column.
