The hydrogen chloride produced by cooling and drying is mixed in a certain proportion and enters the fixed bed reactor reaction, which is equipped with the catalyst HgCl2, the carrier is activated carbon, the reaction is the heat release reaction, and the heat released is taken away by circulating cooling water outside the column reactor. The reaction produces vinyl chloride as coarse vinyl chloride, containing HCl, CO2 and other acidic impurities, need to be washed through the water tank and alkali washing tower, remove impurities, to obtain clean VCM gas. Clean gas is then dried, compressed and liquefyed by dryers and full condensers, and liquid vinyl chloride is refined and refined, followed by low boiling point towers and high boiling point towers, which remove low component impurities and high component impurities, respectively, to obtain refined liquid VCM. The production process flow diagram for the vinyl chloride synthesis segment is shown in Figure 3.
