Abstract:
Ethylene dichloride (EDC) is formed via the balanced oxychlorination route
(see ethylene dichloride description). Pure EDC (99 percent) from the
fractionation facilities is feed to the pyrolysis section where it is
thermally cracked to VCM and HC1.
Operating conditions are in the region of 11 bar and 480oC. Conversion is
about 50-60 percent per pass. Furnace effluent is cooled in a quench tower
prior to being fed to VCM fractionation facilities.
