Title: Process for evaporating 1,2-dichloroethane (EDC)

Abstract: A process for evaporating 1, 2-dichloroethane (EDC) prior to its thermal decomposition (pyrolysis) is provided so that it facilitates the heating of the liquid-phase EDC at temperatures below 100.degree. C. to meet the inlet conditions for the pyrolysis zone, while dispensing with the need for an evaporation zone and exploiting sensible heat recovery at the same time. This is achieved in that the liquid-phase EDC is first pressurized to attain a value above its critical pressure (5.36 MPa) and then heated to attain at least its critical temperature (approx. 288.degree. C.).
