The oxygen enriched liquid air passes through the oxygen enriched liquid air channel through the chiller and then throttles to the upper tower for further distillation, the nitrogen at the top of the lower tower of liquid air separation plant passes through the nitrogen channel to the condensing evaporator for condensation into liquid nitrogen. A portion of the liquid nitrogen is passed through the liquid nitrogen pipeline as reflux to the lower column, while the other portion is sub-cooled by the chiller to the upper column for further distillation. The dirty liquid nitrogen passes through the dirty liquid nitrogen channel and the lean liquid air passes through the lean liquid air channel to the upper tower for further distillation after being sub-cooled by the chiller respectively. In the condensing evaporator nitrogen is condensed at the same time, liquid argon is evaporated as rising gas, and reflux liquid nitrogen, oxygen-rich liquid air between the packing heat transfer, mass transfer oxygen, nitrogen separation, the bottom of the upper tower to get high purity liquid oxygen, through the liquid oxygen pipeline out of the cold box, the middle to get argon containing 8%-12% of the fraction, sent by the pipeline into the argon system can be made argon and through the fine argon pipeline out of the cold box.

The classical single column process is the first one to be used in industrial application. However, there are many disadvantages in the classical single column process. One is that oxygen and nitrogen cannot be produced simultaneously, and the other is that the oxygen extraction rate can only reach about 70%. There are two improvement schemes to solve the defects of classical single column process. One is the curren...
