Abstract
Process for the manufacture of 1,2-dichloroethane (DCE) starting from a stream of ethane which is subjected to a catalytic oxydehydrogenation (ODH) producing a gas mixture containing ethylene, then dried and subjected to an absorption to be separated into a fraction enriched with the compounds that are lighter than ethylene containing some of the ethylene conveyed to a chlorination reactor in which most of the ethylene is converted to DCE, and into a fraction F1. Fraction F1 is then subjected to a desorption to be separated into a fraction enriched with ethylene conveyed to an oxychlorination reactor in which most of the ethylene is converted into DCE, and into a fraction F3.
