Ethane to vcm patent
WebVCM production. A prime candidate for an alternative hydrocarbon from which VCM may be produced is ethane. Not only is ethane cheaper than ethylene, but the chemistry of its conversion to VCM has distinct advantages. For example, the favoured oxychlorination reaction is a single step process in which ethane can be directly converted to VCM: Web4. The molar ratio of chlorine to ethane is from 0.2 to 1.2:1, and the molar ratio of oxygen to ethane is from 0.005 to 0.5:1. The hot gaseous mixture is introduced into reaction chamber 6 of gas-gas reactor 5. Ethane gas in line 7 is preheated in heat exchanger 8, and enters reactor chamber 6 simultaneously with the stream of chlorine and oxygen.
