ABSTRACT OF DISCLOSURE This invention relates to a relatively simple, efficient and economical improvement in the process for recovering odoriferous sulfur-containing compounds from a gas stream containing a member selected from the group consisting of hydrogen sulfide, lower alkyl mercaptans, lower alkyl sulfides and lower alkyl disulfides by contact with an aqueous alkaline slurry of activated carbon. The improvement comprises oxygenating said slurry and intro- ducing it to the top of an enclosure containing packing and passing it downwardly over said packing under laminar flow conditions, said gas being passed transversely through the packing in contact with said slurry, whereby the carbon has a greater effective concen ?tion at the contacting surface than in the bulk of said slurry. An apparatus is also described for carrying out the process.
