There are two adsorption towers a and B equipped with special zeolite molecular sieve. When the clean compressed air enters the inlet end of tower a and flows to the outlet end through zeolite molecular sieve, N2 and co2h2o are adsorbed by it, and the pro
Smelting process: in the steelmaking process blowing with high-purity oxygen, oxygen and carbon and phosphorus, sulfur, silicon and other oxidation reaction, which not only reduces the carbon content of steel, but also helps to remove phosphorus, sulfur,
