| Abstract: | The main roles of each section of rectification tower of the air separation plant are briefed, and the formula to calculate the ascending gas volume, descending liquid volume and the liquid-gas ratio of each tower section are listed. The affect on the liquid-gas ratio in each section of rectification tower and on the argon and oxygen extraction ratio of the air separation plant by various technical processes （inner compression of liquefied oxygen, Lachman air, extraction of medium-pressure gaseous nitrogen from lower tower, inner compression of liquefied nitrogen and production of liquefied nitrogen, liquefied nitrogen product ） is discussed through a calculation example. |
