Production Of Vinyl Chloride From Ethylene

Today vinyl chloride is almost exclusively manufactured by thermal cleavage dehydrochlorination of 1 2 dichloroethane edc.

Production of vinyl chloride from ethylene.

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. Ethylene is made from ethane by cracking ethane and then ethylene is used for production of vinyl chloride. The present invention is directed to a device and method for the production of vinyl chloride monomer vsm of ethane and ethylene. The vinnolit process for the production of vinyl chloride monomer vcm from ethylene and chlorine proceeds via two different routes.

In the direct chlorination as well as in the oxychlorination process ethylene dichloride edc is produced. Flow sheet of production of ethylene dichloride. Production of vinyl chloride by this method 21. In one aspect a process for producing vinyl chloride from ethane ethylene involving.

In particular the present invention is directed to methods of production of vinyl chloride monomer where 1 a significant number of both ethane and ethylene are present in the input streams in the associated reactor and 2 hydrogen chloride located in the. By the older method addition of chlorine to 2. The present invention is directed to a device and method for the production of vinyl chloride monomer vcm of ethane and ethylene. Hence to save the processing cost for manufacturing ethylene numerous attempts have been made to convert ethane directly to vinyl chloride.

The feedstock for the thermolysis can be obtained from two routes. Vinyl chloride from ethylene direct route vinyl chloride from ethylene edc direct chlorination ch 2ch 2 cl 2 clch 2ch. A process is disclosed for the production of ethylene dichloride from ethane. 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.

By the more modcrn process oxychlorination of ethylene. Production of vinyl chloride from ethylene. Ethane is introduced into an autothermic self sustaining cracking zone. Vinyl chloride is produced from ethylene in two step process.

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.
