External Compression ASU

Through deep optimization of the process, the operating pressure of the raw material air compressor can be reduced as low as 0.43 MPa, the upper and lower towers are all equipped with high-efficiency distillation packings, and the main cooling adopts new multi-layer heat exchangers. After the technology is put into use, it has saved millions of dollars of energy costs for dozens of our end users.

Product Description

External compression ASU :

Through deep optimization of the technological process, the operating pressure of the raw material air compressor can be minimized to 0. 43MPa. Both upper and lower columns are high-efficiency packed columns. The main cooling is a new multi-layer cooling facility. This patented technology is mature, featuring simple process and stable and convenient operation! After being put into use, it has helped save tens of millions of energy costs on a yearly basis for dozens of enterprises.
