ammonia

The industrial production of synthetic ammonia provides sufficient raw materials for the manufacture of various nitrogen fertilizers. Ammonia is also used in the production of various amine and acyl compounds, and a large amount of ammonia is used in the production of explosives. Ammonia is a medium temperature refrigerant suitable for large and medium refrigerators, and it is the earliest and most widely used refrigerant. Ammonia is also metallurgical, pharmaceutical and other industrial raw materials.

chlorine

Chlorine gas kills bacteria and is used to purify water. It is also used to treat some industrial wastewater, such as oxidation of hydrogen sulfide, cyanide and so on, to eliminate its toxicity. Chlorine gas can produce a variety of chemical products, used in the manufacture of plastics, pesticides, synthetic fiber, synthetic rubber, etc., also used in the production of chloride, hydrochloric acid and chlorine-containing solvents. Chlorine gas can also be used in the production of final chlorine-free chemical products, such as glycerol (glycerol), ethylene glycol, etc.

Vertical acetylene compressor

Acetylene gas

Acetylene gas is one of the important raw materials of organic synthesis, and it is also one of the monomers of three synthetic materials (rubber, plastic and fiber). Used in the pharmaceutical industry to manufacture contraceptives. Used as carrier gas on atomic absorption analyzer. The important uses of dissolved acetylene are metal welding and cutting, plating, surface quenching and hot working. In addition, the earliest use of acetylene gas is used for lighting, the main use of the occasion for navigation lights.

hydrogen

Hydrogen gas is used as protective gas, reaction gas, carrier gas, combustion gas and so on in various industries of national economy. In the production of petrochemical industry, hydrogen-containing gases of different components are used as feedstock gas and hydrogenation gas for the production of synthetic ammonia, methanol and petroleum refining. The feedstock gas for hydrogenation of organic matter. In the metallurgical industry, hydrogen as reducing gas and shielding gas is widely used in the production and processing of tungsten, molybdenum and titanium. Production and rolling of sheet steel, strip steel, silicon steel sheet; Precision alloy, powder metallurgy material production. In the electronic industry, high purity hydrogen is widely used, mainly for the production of electronic materials, semiconductor integrated circuits and electrical vacuum main devices. In the production of building materials and light industry, hydrogen is often used as protective gas, combustion gas, such as quartz glass, artificial gem production using hydrogen oxygen flame to obtain high temperature; In float glass production hydrogen is used as a protective gas etc. Hydrogen is used as coolant of generator set in electric power industry. Balloons and air bags use hydrogen as filling gas. Liquid hydrogen is an important liquid fuel for aerospace and rocket. Using hydrogen to make fuel cells. In addition, the use of hydrogen-containing fuel in cars and the treatment of chemical waste with hydrogen to make useful products have been or will soon become a reality.
