The scheme integrates VCM (vinyl chloride monomer) production with brine electrolysis to save energy. A CSTR (Continuous Stirred Tank Reactor) simultaneously neutralises hydrogen chloride and reacts with the remaining ethylene-dichloride. Coupled with a novel energy integration scheme, the final result is a more than one-third reduction in the overall energy demand of both electrolysis and vinyl chloride production, as well as a drastic reduction in the need to extract seawater for electrolysis.
