To accelerate the elimination of industrial solid waste generated by serious environmental pollution due to outdated production processes and equipment as well as to continue to improve the level of industrial green development, the Ministry of Industry and Information Technology recently announced the Deadline for the Elimination of Industrial Solid Waste Generated by Serious Pollution of Outdated Production Process Equipment, which goes into effect on January 1, 2022
The six kinds of petrochemical chemical process equipment that are to be phased out are:
- Illegal small-scale oil refining from waste rubber and plastic
- Intermittent coke method carbon disulfide process
- High-mercury catalyst production units (mercury chloride content above 6.5%)
- Acetylene method polyvinyl chloride production equipment using high mercury catalysts
- Production units with calcium roasted chromium compounds
- Production equipment that uses mercury or mercury compounds to produce sodium methanol, potassium methanol, sodium ethanol, potassium ethanol, polyurethane, acetaldehyde, caustic soda, and pesticide
Compared with the draft for opinions, the following three petrochemical processes were deleted: (a) acid-clay process used mineral oil recycling, (b) used mineral oil kettle distillation clay refining process, and (c) chromium salt production in the sulfuric acid method of sodium dichromate and chromic anhydride production.
In addition, the document also includes illegal small-scale coking in the iron and steel industry (including improved coke ovens), light fatty acid process for producing tertiary amines in light industry, fuming sulfuric acid sulfonation process, etc.
