Production Of Vinyl Chloride From Ethylene

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.

The feedstock for the thermolysis can be obtained from two routes. Today the balanced ethylene is responsible for well over 90 of the world s vinyl. In the direct chlorination as well as in the oxychlorination process ethylene dichloride edc is produced. Today vinyl chloride is almost exclusively manufactured by thermal cleavage dehydrochlorination of 1 2 dichloroethane edc.

Production of vinyl chloride by this method 21. Flow sheet of production of ethylene dichloride. 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. By the more modcrn process oxychlorination of ethylene.

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. Ethylene is made from ethane by cracking ethane and then ethylene is used for production of vinyl chloride. Vinyl chloride is produced from ethylene in two step process. 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. Ethane is introduced into an autothermic self sustaining cracking zone. Vinyl chloride from ethylene direct route vinyl chloride from ethylene edc direct chlorination ch 2ch 2 cl 2 clch 2ch. By the older method addition of chlorine to 2.

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. The present invention is directed to a device and method for the production of vinyl chloride monomer vcm of ethane and ethylene. 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. In one aspect a process for producing vinyl chloride from ethane ethylene involving.

Hence to save the processing cost for manufacturing ethylene numerous attempts have been made to convert ethane directly to vinyl chloride.
