Abstract
The gas stream obtained from the pyrolysis of solid organic wastes and containing chlorine in the form of hydrogen chloride is processed to obtain a substantially chlorine free pyrolytic oil. The gas stream is first contacted with a hydrocarbon immiscible with the pyrolytic oils to quench the gas stream and reduce the gas stream temperature close to the dew point of water. This forms a two phase condensate of the quench hydrocarbon and pyrolytic oil. The phases are separated, the pyrolytic oil recovered and the hydrocarbon recycled as the quench. The resultant gas stream is then treated for removal of hydrogen chloride from the gas stream for disposal or recovery of hydrochloric acid.
