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.

Production of vinyl chloride from ethylene. The present invention is directed to a device and method for the production of vinyl chloride monomer vcm of ethane and ethylene. By the older method addition of chlorine to 2. Today the balanced ethylene is responsible for well over 90 of the world s vinyl. Ethylene is made from ethane by cracking ethane and then ethylene is used for production of vinyl chloride.

In one aspect a process for producing vinyl chloride from ethane ethylene involving. Production of vinyl chloride by this method 21. 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 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.

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

By the more modcrn process oxychlorination of ethylene. The vinnolit process for the production of vinyl chloride monomer vcm from ethylene and chlorine proceeds via two different routes. The present invention is directed to a device and method for the production of vinyl chloride monomer vsm of ethane and ethylene. Vinyl chloride from ethylene direct route vinyl chloride from ethylene edc direct chlorination ch 2ch 2 cl 2 clch 2ch.

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. Production of vinyl chloride from ethylene. Hence to save the processing cost for manufacturing ethylene numerous attempts have been made to convert ethane directly to vinyl chloride. A combining ethane ethylene or mixtures thereof with an oxygen source and a chlorine source in a reactor containing a suitable catalyst under conditions sufficient to convert substantially all of the c2 hydrocarbon fed and to produce a product stream comprising vinyl chloride and hydrogen chloride.
