Gas carbon dioxide is mainly used as raw materials for soda ash, chemical fertilizer (ammonium bicarbonate, urea) and synthetic methanol and inorganic salt industries. It is also used for steel casting quenching, lead white manufacturing, dry ice manufacturing, etc. Liquid carbon dioxide is used in welding, fermentation industry, cooling and cooling beverage industry, sugar industry and medical local anesthesia. It is also used as anti foaming agent for large cast steel, plant growth accelerator, anti oxidant and fire extinguishing agent. Solid carbon dioxide is used in penicillin production, fish, cream, ice cream and other food storage and low-temperature transportation.
