How does the liquefaction unit liquefaction oxygen and nitrogen, and what role does it play in the oxygen plant?

The liquefaction unit is divided into low pressure liquefaction cycle and medium pressure liquefaction cycle, and the circulation medium can be air or

Mar 27, 2013

What is the working principle of small air separation equipment level and nitrogen discharge valve?

Oxygen and nitrogen discharge valve is used to control the purity of oxygen and nitrogen and low pressure. When the purity of oxygen is lower than the

Mar 26, 2013

What is the main principle of the small air separation plant to shorten the start-up time?

This is because the temperature in the air separation tower in the start-up phase is away from the normal working temperature (-172 ~ -194 ℃) is relat
