| Abstract: | Four kinds of schemes for recycling cold energy in vinyl chloride synthesis were intru- duced. Through heat exchange between the dewatered gas mixture from conversion procedure and low- temperature return cooling water, heat exchange between tail gas from rectification procedure and low- temperature return cooling water, the cold energy of mixed gas and the cold energy of tail gas were fully recycled, and 1.14 million RMB ￥economic effects could be generated per year. |
