TH32358B - Method and air separation equipment - Google Patents

Abstract

Methods and equipment for air separation That eliminates oxygen with vapor stream From a single tower nitrogen generator and then dividing into two auxiliary currents Condensation of the two currents assist each other and then combine to eliminate within the removal tower. To produce highly pure liquid oxygen at the bottom of the condensing tower, one of the two assist currents in the re-boiler and the bottom of the removal tower Another stream of two rescue flows Together to be condensed inside the main condenser Used in conjunction with the body Single tower nitrogen generator

1. Air separation method that consists of cooling, compressed air stream and purification. It is the optimum temperature for repeated distillation. Repeat the air flow. To produce oxygen that There is a vapor with less heavy elements. Division of the abundant oxygen currents It consists of oxygen with two auxiliary currents and the separation of the two auxiliary currents and the removal of the two auxiliary currents in the removal tower of the light element. To generate high-purity liquid oxygen at the bottom of the tower in the removal tower One of the two streams helping each other
