Dust removal efficiency of sieve tray tower

What is the function of biogas purification

As the air of the air separation plant of the molecular sieve purification process removes impurities such as moisture and carbon dioxide through the adsorption of the molecular sieve, compared with switching the purification process, the start-up operation is simple and easy to control. It doesn't need to consider the complex influences such as self-cleaning of water and carbon dioxide, precipitation of water and carbon dioxide in the expansion machine, and the attention of starting process mainly focuses on giving full play to the refrigeration capacity of the expansion machine, reasonably allocate cooling capacity and fully cool the equipment. It can be divided into three stages: cooling equipment, accumulation of liquid and adjustment of rectification working condition. Compared with the start-up mode of switching process, it can be called "comprehensive cooling method" or "one-time cooling method ". The following points should be paid attention to when starting the operation: 1...
