Composition of the PSA nitrogen production adsorption tower
Thread Content
This post was last edited by you*n*nyou on 2011-9-1 21:00. Our factory’s existing nitrogen production unit is said to operate on the pressure swing adsorption principle; the PSA system of this unit consists of two sets of CMS adsorption towers. Could that friend from overseas provide a detailed explanation? Those who have relevant information, please share it. Thank you
Pressure swing adsorption is very common and is mainly used for low flow rates. As stated in your title, it’s not pressure swing adsorption
Reply to 2# jlchina: Please explain in detail. Thank you
Search on the forum; there are many. For hydrogen production via pressure swing adsorption, as far as I know, the maximum capacity of a single unit is around 1000 Nm3/h. Air separation for nitrogen production generally involves cryogenic air separation to produce liquid nitrogen and liquid oxygen. It’s generally above 3000 Nm3/h, I guess
Simply put: Pressure swing adsorption is generally used solely for nitrogen production, and systems with low flow rates are also referred to as nitrogen generation units. Air separation generally produces two products: nitrogen and oxygen, and it is usually implemented as part of the infrastructure in large enterprises.
At present, there are three methods for industrial air separation technology in our country: cryogenic air separation, PSA and VPSA pressure swing adsorption, and membrane separation. The characteristics of each method are as follows: (1) Characteristics of cryogenic air separation: It is necessary to use large-scale installations, with a capacity of 10,000–78,000 m3/h, in order to achieve low energy consumption per unit of output and low investment costs for such installations. (2). Characteristics of PSA and VPSA pressure swing adsorption:
It’s a pressure swing adsorption nitrogen generator, right? Add me on QQ. 952290322
