Abstract
PURPOSE: To perfectly remove free chlorine by a method wherein dilute ethylene and vinyl chloride contained in a waste gas are chlorinated to produce EDC and ethane trichloride and the obtained gaseous fluid is washed with an aqueous solution of caustic soda or sodium carbonate.
CONSTITUTION: Ethylene, HCl and O2 contained in a gas are reacted to produce ethane dichloride and, from the product gas, ethane dichloride is separated to carrying out oxychlorination reaction. In this time, the produced waste gas containing ethylene and vinyl chloride is sent to a reaction tower 3 from a line 1. Chlorine is supplied in said reaction tower from a line 2 and ethylene and vinyl chloride in the waste gas are reacted with said chlorine and chlorinated in the presence of a catalyst which is EDC stored in an intermediate tank 8 and recirculated through the reaction tower 3 by a pump 5 to be converted to a gaseous fluid containing EDC and ethane trichloride. This gaseous fluid is sent into a washing tower 10 through a pipe 9 and washed with a caustic soda liquid recirculated through pipes 11, 14 by a pump 12 to remove an acid therein. The gas washed in the washing tower 10 is discharged out of the system through a pipe 18.
