Oxygen compressor issues
Thread Content
I plan to install an oxygen compressor with a gas production capacity of 34,000–38,000 Nm3/h and an outlet pressure of 8.3 MPa. Could industry experts recommend some suppliers?
There should be quite a few suppliers on the forum
I only see Hangyang and Xi’an Jiaotong University; I don’t see the others
Quality is what matters, not quantity, right?:lol
I want to learn more about a few more companies, at least to meet the supplier’s recommendation requirements. We require at least five suppliers
I’m seeking advice from experts; since no one is helping, I’ll handle it on my own
Is air separation a externally compressed process? Why wasn’t the internal compression liquid oxygen pump process chosen? With such a large capacity, it is likely that a centrifugal type would be the suitable choice. In China, Hangyang and Xi’an Jiaotong University are involved in this field; Hangyang has adopted technologies from Linde and Hitachi. As for the oxygen compressors developed by Xi’an Jiaotong University, it’s not clear whether they are developed in collaboration with Shenyang Steam Turbine Group Abroad, companies such as Sulzer (now part of Turbomachinery), Linde, Hitachi, and Ebara should be viable options.
First of all, thank you for your advice. It’s hard to answer why external compression was chosen; the boss keeps changing his mind constantly and does whatever comes to him, so there’s no choice but to follow his orders. With such high pressure, it is still debatable whether centrifuges are the appropriate choice. I’ll learn more about these foreign companies
Yes, I also feel that the pressure is high, but with such a large volume capacity, the reciprocating compressor is way too big.
Several domestic manufacturers of imported centrifugal air compressors now state clearly that their compressors can only compress air and nitrogen, and not other gases. Materials with a higher level of safety are required for oxygen use.
