Abstract
A process for specific energy saving, especially in processes involving the oxychlorination of ethylene, facilitates recovery of as much sensible heat to be used for other purposes. In the process the gas mixture leaving the oxychlorination reactor is cooled before it enters the quenching column and the heat recovered is then used to preheat the ethylene recycle gas feed stream.
