| Abstract: | The application of chlorhydric acid stripping process to the treatment of waste acid discharged during the production of PVC is introduced.The stripping product-HCl gas can be used as raw materials for the synthesis of VCM.The recovery amount of HCl gas is up to 1 800 t/a ,with the recovery percent of 85%.So the economic effects gained is 1.598 million RMB$ and 9 000 m 3 water can be saved per year.Meanwhile,the waste acid is treated and the water pollution caused by discharged CaCl 2 and the air pollution caused by H 2S are also prevented. |
