Industry waste acid include such as sulfuric acid, hydrochloric acid, citric acid, lactic acid and other inorganic and organic acids, it is a very important chemical raw materials, almost all industrial uses, directly or indirectly, it concentrated hydrochloric acid manufacturers, wherein the acid the intermediate chemical raw materials used in the production process and as much excess waste acid because they can not continue to use and requires treatment after discharge chemical industry has become a major environmental problem. In this context hydrochloric acid factory in Nantong, a membrane technology-based Sichuan hydrochloric acid plant, successfully developed a waste acid recycling equipment, it has easy to implement technological transformation, high return on investment, easy operation, easy maintenance, low operating costs, high degree of automation. Return can deal directly with the spent acid waste acid recycling equipment, change harmful to treasure, for enterprises to solve environmental problems but also brings a lot of money for money, use field with a promising future, it has a tremendous return on investment value. Use boiling water to remove scale (chemical equation) CaCO3 + 2HCl = CaCl2 + H2O + CO2 ↑ and Mg (OH) 2 + 2HCl = MgCl2 + 2H2O) laboratory preparation of carbon dioxide (chemical formula): CaCO3 + 2HCl = CaCl2 + H2O + CO2 ↑ and iron, magnesium and other metals produced by the reaction of a small amount of hydrogen required chemistry experiment (chemical equation is: Fe (Mg) + 2HCl = FeCl2 + H2 ↑) of concentrated hydrochloric acid manufacturers | hydrochloric acid plant | Zhengzhou Longda Chemical by the Zhengzhou Ronda Chemical Products Limited.
