Claim:
A process for the manufacture of 1,2-dichloroethane from a hydrocarbon source comprising: a) subjecting said hydrocarbon source to cracking to produce a product mixture comprising ethylene and other constituents; b) separating said product mixture into at least one ethylene fraction having a purity of less than 99.8% and into a heavy fraction C comprising ethane and compounds comprising at least 3 carbon atoms; c) conveying said at least one ethylene fraction to a chlorination reactor and/or an oxychlorination reactor to convert most of the ethylene present within said at least one ethylene fraction into 1,2-dichloroethane; d) separating said 1,2-dichloroethane from one or more streams of products derived from said chlorination reactor and/or said oxychlorination reactor and conveying said 1,2-dichloroethane to a pyrolysis oven; and e) conveying said heavy fraction C to said pyrolysis oven in d) as fuel.
