Description

The process flow includes dry acetylene production from calcium carbide, chlorination and hydrogenation of acetylene to produce vinyl chloride, suspension PVC production from vinyl chloride using Japanese CHISSO polymerization technology, and PVC production from resin paste using polymerization technology packages. Users of this data set should ensure proper representation of the unique production technology while leveraging the data for environmental impact assessment in life cycle assessments (LCA). It's important to factor in regional context, given that the production subsidiary is located in southeastern China. Lifecycle stages, such as raw material acquisition, manufacture, distribution, use, and end-of-life, should be modeled considering the specific impacts of each stage relevant to PVC production. Methodologically, attention should be given to potential impacts of chlorinated hydrocarbon emissions and energy consumption patterns.

Technology

The technical links of this process include: dry process of acetylene by calcium carbide, electrolysis of salt water to produce hydrogen chloride, addition of acetylene and hydrogen chloride to produce vinyl chloride, and polymerization of vinyl chloride to produce polyvinyl chloride.
