In a continuous process for the complete removal and recovery of 1,2-dichloroethane from the waste gases resulting from the production of 1,2-dichloroethane by oxychlorination of ethylene with hydrogen chloride and oxygen, which are passed over activated carbon and then burned at temperatures above 900 ° C and finally cleaned of hydrogen chloride and chlorine, the activated carbon being freed from hot 1,2-dichloroethane and regenerated with hot steam, the 1,2-dichloroethane-laden flue gas having a temperature of 1 ° to 10 ° C. is heated to a Temperature that is at least 20 ° C above the respective dew point for water and conducts it over the activated carbon. The invention also relates to a device for the continuous implementation of the method. |
