ABSTRACT:
Organic refuse is pyrolyzed to form disposable solids and gas. The gas is washed at a temperature well above 100.degree. C. with wash oil, which is recirculated. Spent wash oil is pyrolyzed with contaminants and further organic refuse. The washed gas is filtered through sorption means to remove acid and or other noxious gases therefrom before being cooled well below 100.degree. C. to condense water vapor and other constituents having boiling points within the range of from, e.g., 75.degree. to 150.degree. C. After separating the resulting condensate, thus-purified combustion gas is used, e.g., as a fuel source for the organic-refuse pyrolysis.
