Application:
Large amounts of oxygen are required for coal gasification projects; Cryogenic plants producing 3000 tons/day are found in some projects. In steelmaking oxygen is required for the basic oxygen steelmaking. Large amounts of nitrogen with low oxygen impurities are used for inerting storage tanks of ships and tanks for petroleum products, or for protecting edible oil products from oxidation.
