Tonnage oxygen plants and products for specific users

摘要

Processes such as iron and steel, petrochemicals, petroleum refining, gasification, power generation are all amongst the large scale users of oxygen, some installations consuming well over 1500-2,500 MTPD. Each has a requirement for specific supply - pressure, purity, impurity levels as well as coproduct requirements. The effect of these on the choice of tonnage oxygen plant cycle configuration, equipment and products, as well as co-products, is reviewed in this paper. A brief review of tonnage plant cycles and co-product arrangements is included and the potential for process integration is mentioned.
