Air separation corollary equipment

The super large air separation equipment is composed of air compression system, large air precooling system, super large molecular sieve purification system, air pressurization system, pressurized turbine expander system and super large distillation system and heat exchange system. Due to the large size of the supporting unit equipment and the high manufacturing process requirements, the supporting valve selection is particularly important, which is directly related to the production safety, system controlling performance, production quality and investment costs.
