Description
technical field [0001] The invention specifically relates to a production equipment and process of anhydrous hydrogen fluoride. Background technique [0002] Industrial anhydrous hydrogen fluoride is a chemical product with a wide range of uses. The appearance is more than 99% hydrofluoric acid of colorless fuming liquid, which is easy to gasify under reduced pressure or high temperature. It is mainly used to prepare fluorine salts, fluorohalogenated hydrocarbons, fluorine refrigerants, corrode glass, impregnate wood, and electrolyze elemental fluorine, etc. [0003] Anhydrous hydrogen fluoride has been widely used in atomic energy, chemical industry, petroleum and other industries. It is a strong oxidizing agent and the basic raw material for preparing elemental fluorine, various fluorine refrigerants, inorganic fluorides, and various organic fluorides. It can be formulated into various It is used in water hydrofluoric acid, used in the manufacture of graphite and as a cat...
