Ethylene Dichloride-Balanced Oxychlorination

Abstract

There are two reaction sections in this process. In the first section, high purity ethylene and chlorine (99+ percent) react in a liquid-phase, non catalytic reactor at about 11 bar and SOOC. In the second section, ethylene, air or oxygen, and HCl react in a vapour phase catalytic reactor at 260-3l0oC and a pressure of 2-8 bar. Reactor products separately. It is other light ends and from both sect ions are caustic and water then passed through fract ionat ion to separate heavy ends to 99 percent purity EDC product.
