Regarding the selection of air separation technology
Thread Content
Regarding the selection of air separation technology... Our company plans to install several sets of air separation units worth 80,000 each. We have currently been in contact with Hangyang, Linde, Air Liquide, and APCI. Which company’s technology would be the best choice? And please predict which company’s technology will be chosen in the end? You’ll get points if you guess correctly! I guess: we might choose Air Liquide’s technology.
Regarding the manufacturers you mentioned, Hangyang in China has quite good technical capabilities. As for those foreign companies, I used to work for Linde, and I think Linde’s technology and equipment are excellent; the Shenhua coal-to-oil project uses Linde’s equipment, but the prices are quite high!

3# houzi910 Agree! You get what you pay for.
8w’s air separation capacity is quite large. Which region are you in? It’s impossible to tell which one to use!

Hangyang does not have any actual performance records related to 80,000 units; during the technical exchange meeting at Hangyang in March, I recall that only a few contracts for 80,000-unit air separation units were signed. But to be honest, air separation technology is now quite mature; the major obstacle to the development of larger-scale air separation facilities is actually the limitations related to transportation conditions, rather than technical constraints.
Hangyang is cheap; if one is looking for better value for money, Air Liquide is a good option. I guess Air Liquide will win the bid
I agree with what this brother said. The localization of large-scale equipment requires support from large-scale projects carried out by domestic manufacturers; it’s not possible to rely solely on imports. Foreign companies also developed over time, with the backing of continuous large-scale projects, taking things step by step.
The main challenge in manufacturing 80,000 cubic meters of oxygen lies in the air compressors, not in the cryogenic tanks used for oxygen production. To support the domestic industry, choosing a domestically produced compressor offers good quality at a low cost; however, if high quality and low energy consumption are desired, one must pay more for imported compressors. Linde seems to be a good option, but careful consideration is needed when selecting air compressors. SIEMENS, MAN, and ATLAS do not have very impressive performance records, and there are no domestic alternatives available, so careful selection is essential.
Support domestic products! ! Our unit also uses Hangyang products, and it operates stably! But I’m not sure what kind of thing a large device like 80,000 will actually be like!
Where is the project of the original poster? Support!
