In order to speed up the elimination of outdated production processes and equipment that cause serious environmental pollution, and continue to improve the level of industrial green development, the Ministry of Industry and Information Technology recently announced the "List of Outdated Production Processes and Equipment for Eliminating Industrial Solid Wastes that Cause Serious Environmental Pollution" ", effective from January 1, 2022.

There are 6 types of petrochemical and chemical process equipment to be phased out within a time limit, namely, waste rubber and plastic soil refining process; intermittent coke carbon disulfide process; high-mercury catalyst production equipment (mercury chloride content above 6.5%); acetylene method using high-mercury catalyst Polyvinyl chloride production equipment; calcium roasting chromium compound production equipment; sodium methoxide, potassium methoxide, sodium ethoxide, potassium ethoxide, polyurethane, acetaldehyde, caustic soda, and pesticide production equipment that use mercury or mercury compounds.

u3000u3000 Compared with the draft for comments, the sulfuric acid/white earth method waste mineral oil re-refining process; the waste mineral oil kettle-type distilled soil refining process; the sulfuric acid method in the production of chromium salt to produce sodium dichromate and chromic anhydride three petrochemical chemical processes have been deleted.

u3000u3000 In addition, the "List" also includes the local coking (including improved coke ovens) in the iron and steel industry, the light-industrial fatty acid method for preparing tertiary amines in the light industry, and the oleum sulfonation process.

u3000u3000 It is reported that the "List" proposes outdated production technology and equipment that need to be eliminated for industries such as steel, non-ferrous metals, gold, medicine, machinery, shipbuilding, and light industry. The year in parentheses after the entry is the elimination period, and the entry without the elimination period is the national industrial policy that has been explicitly ordered to be eliminated or is eliminated immediately.
