What is the cryogenic distillation?
Nov 17, 2021
Author: DEAR AST

There are three kinds of deep cold air separation processes in the textbook of deep cold air separation, two of which are single tower process and one with double tower. Only one pure component of oxygen nitrogen can be produced in single tower process, and two pure components can be produced simultaneously in double tower process. When the deep cold air separation is industrialized, the theory of thermodynamics has been fully mature, while distillation is in the transition period from distillation to distillation. The capacity of distillation in the textbooks of deep cold air separation reflects the theoretical characteristics of distillation in this period. However, the thermodynamics theory has been fully developed and mature in the textbooks. Only a little consideration can be found that the three deep cold air separation processes in the textbook are different from the normal distillation process. However, it is easy to derive the heat pump from the self thermal distillation if we carefully examine the heat supply mode. The most important and common way of heat pump is the so-called heat transfer.

 

DEAR Air Separation focuses on R & D, manufacturing and installation of various complete air separation equipment and provides comprehensive services for gas investment, EPC project general contracting, equipment operation management and bioenergy. DEAR Air Separation has the capacity to design and produce more than 30 large and medium air separation equipment annually, and has been successfully serving more than 1000 customers worldwide.

 

We will devote great money to build intelligent production workshop to ensure the quality of products close to zero defects, improve the accuracy of biogas purification equipment and shorten the scheduled period. At the same time, it has a number of patent technologies, of which two ultra-low pressure energy saving patents are the leading domestic level, which can reduce the energy consumption of biogas purification equipment by 5% - 15%, and save the operation cost.
