PCT No. PCT/EP96/01514 Sec. 371 Date Dec. 1, 1997 Sec. 102(e) Date Dec. 1, 1997 PCT Filed Apr. 9, 1996 PCT Pub. No. WO96/31272 PCT Pub. Date Oct. 10, 1996A process for the removal of dust from gas that has been produced by low temperature carbonization is provided. The process separates solid particles by means of washing oil in a spray washer that also cools the gases that have been produced by low temperature carbonization. The process includes intensively wetting the gases that have been produced with oils that have been condensed out of the stream of the gas. At least a first and second washing stage is provided in the spray washer. The mass flow comprising the washing oil and condensate is collected in the second washing stage and subdivided. Thereafter, the mass flow is fed to both the first and second washing stage as recirculated and recycled washing oil.
