| Abstract: | The gas,liquid and solid emissions from the production of VCM by calcium carbide method were treated effectively in Tangshan Chlor - Alkali Co. ,Ltd. Taking 300 kt/a PVC as example,benefits of 12. 945 million RMB ￥ could be created by recovering the rectification tail gas of VCM through pressure swing adsorption,and benefits of 3. 208 million RMB ￥could be created by recovering hydrogen through adopting adsorption hydrogen- making process; benefits of 68.97 million RMB￥ could be created by producing sodium carbonate through substituting the discharged carbide slags for limestone; benefits of 3 million RMB￥could be created by recovering VCM througy the desorption of hydrochloric acid and electric cost of 1. 267 2 millon RMB ￥ could be saved through recovering and converting heat from hot water. |
