Localization of large air separation unit

The localization of large air separation unit can not only save the investment cost of the project, but also can not be restricted by foreign investors in the after-sales maintenance service, and can ensure the stable and safe operation of the air separation project. Distillation column is one of the main core units of air separation unit. Because the diameter of distillation column supporting large coal chemical air separation unit is up to and limited by transportation, high-throughput tray and packing are needed. This problem is also one of the important issues of large air separation unit localization.

Faq of Localization of large air separation unit

How does the air separation column and expander of high purity nitrogen unit work?

The air separation column mainly includes main heat exchanger, liquefier, distillation column, condensing evaporator, etc. The main heat exchanger, condensing evaporator and liquefier are plate type of heat exchangers. It is a new type of all aluminum metal composite partition heat exchanger. The average temperature difference is small, and the heat exchange efficiency is as high as 98-99%. Distillation column is the unit of air separation. The types of column unit are classified according to the internal parts. The sieve plate column with sieve plate, the bubble cap column with bubble cap plate, and the packed column with packing material. The sieve plate is widely used in air separation distillation column because of its simple structure, easy manufacture and high efficiency. Packed column is mainly used for distillation column with diameter less than 0.8m and height less than 7m. Bubble column is seldom used because of its complicated structure and difficult manufacture.
