Description
In recent years, the production process of China’s caustic soda industry has changed significantly. The proportion of ion-exchange membrane caustic soda is increasing rapidly. Diaphragm caustic soda has been withdrawn year by year in accordance with the guidance of the 2011 version of the “Industrial Structure Adjustment Guidance Catalogue”. By the end of 2017, the proportion of membrane caustic soda was almost completely withdrawn, and the proportion of ion-exchange membrane caustic soda accounted for 99.4%. Ion-exchange membrane caustic soda is produced by electrolyzing salt water by the ion-exchange membrane method. The ion-exchange membrane caustic soda method has the advantages of high quality of caustic soda, low energy consumption, low investment, and high purity of chlorine and hydrogen, and there are no pollution problems such as mercury pollution in the production of mercury soda and asbestos waste in the production of diaphragm soda.
