What is the minimum work in the separation process, and how to save energy in the rectification separation process?

Air is a mixed gas, and the gas separation process cannot be carried out spontaneously. In order to realize the separation of oxygen and nitrogen, wor

Apr 09, 2013

What is the influence of insufficient processing air volume on the rectification working condition?

When the air volume decreases, both the rising steam volume and the recirculation fluid volume in the tower decrease, but the recirculation ratio can

How is the purity of the oxygen generator product expressed?

In the process of production, indicators such as the purity of oxygen products is not less than 99.5%, the purity of nitrogen is not less than 99.99%,

Apr 09, 2013

What are the requirements for the installation of instrument detection pipelines?

All instrument pipelines and pipe fittings used for oxygen passage should be strictly degreased with carbon tetrachate or alcohol before installation.
