T/CCASC 1002.5-2021 CPC Method for Production of Polymer Vinyl Chloride Safety Operating Procedures Part 5: Vinyl Chloride Polymerization

Scope

Scope: This standard specifies the process safety technology, operational safety, safety conditions for the start-up and shutdown of production equipment, key devices and critical areas, safety regulations for inspection and maintenance, safety regulations for labor protection and working environment, and related emergency response measures in the vinyl chloride polymerization process of vinyl chloride production by the carbide method. This standard applies to the safe operation of the vinyl chloride polymerization process in the suspension method, that is, from the entry of vinyl chloride into the polymerization reactor to the vinyl chloride entering the packaging unit after going through the stripping and drying units.
