Vinyl chloride production refers to the industrial synthesis of vinyl chloride monomer (VCM), an organochloride compound derived from ethylene and chlorine, which serves as the essential building block for polyvinyl chloride (PVC) manufacturing. This segment represents a foundational link within the global petrochemical value chain, requiring precision chemical engineering and stringent safety systems given the hazardous, carcinogenic nature of the intermediate gas.
Vinyl chloride monomer is manufactured through direct chlorination and oxychlorination of ethylene to produce ethylene dichloride (EDC), high-temperature pyrolysis cracking of EDC to yield crude VCM and hydrogen chloride, and multi-stage distillation purification before compression into pressurized storage. Advanced facilities recycle by-product hydrogen chloride back into the oxychlorination step to maximize raw material efficiency and minimize waste.
Vinyl chloride monomer production can be broadly classified by process route. The oxychlorination process, which recycles hydrogen chloride by-product, dominates global production due to its efficiency. The balanced process combines both direct chlorination and oxychlorination in an integrated cycle, while direct chlorination alone is the oldest and least efficient route. By downstream application, VCM output is predominantly directed toward PVC resin production, alongside smaller volumes for copolymer resins and chlorinated solvents.
