Production Of Vinyl Chloride From Ethylene

Production of vinyl chloride from ethylene.

Production of vinyl chloride from ethylene.

In the direct chlorination as well as in the oxychlorination process ethylene dichloride edc is produced. A process is disclosed for the production of ethylene dichloride from ethane. Today vinyl chloride is almost exclusively manufactured by thermal cleavage dehydrochlorination of 1 2 dichloroethane edc. Ethane is introduced into an autothermic self sustaining cracking zone.

Today the balanced ethylene is responsible for well over 90 of the world s vinyl. Overall reaction 2 ch 2ch 2 cl 2 o 2 2 ch 2chcl h 2o balanced process for vinyl chloride production no generation of hcl 95 of the world s vcm is produced utilizing the balanced process. In one aspect a process for producing vinyl chloride from ethane ethylene involving. Vinyl chloride from ethylene direct route vinyl chloride from ethylene edc direct chlorination ch 2ch 2 cl 2 clch 2ch.

Ethylene dichloride vinyl chloride or mixtures of ethylene dichloride and vinyl chloride can be recovered as product with substantially complete utilization of the hydrogen chloride produced. In particular the present invention is directed to methods of production of vinyl chloride monomer where 1 in the input streams into the appropriate reactor contains significant amounts of both ethane and ethylene 2 hydrogen chloride in the stream exiting. However as ethylene became more plentiful in the early 50 s commercial processes were developed to produce vinyl chloride from chlorine and ethylene via edc namely the balanced ethylene route. The present invention is directed to a device and method for the production of vinyl chloride monomer vsm of ethane and ethylene.

Vinyl chloride is produced from ethylene in two step process. By the more modcrn process oxychlorination of ethylene. The feedstock for the thermolysis can be obtained from two routes. Hence to save the processing cost for manufacturing ethylene numerous attempts have been made to convert ethane directly to vinyl chloride.

Ethylene is made from ethane by cracking ethane and then ethylene is used for production of vinyl chloride. Flow sheet of production of ethylene dichloride. The present invention is directed to a device and method for the production of vinyl chloride monomer vcm of ethane and ethylene. Production of vinyl chloride by this method 21.

By the older method addition of chlorine to 2.
