ABSTRACT:
An apparatus for the cooling of a cracking-gas stream comprises a vertical pipe through which the cracking-gas stream is conducted and opening into a larger pipe section which surrounds the first-mentioned pipe across an annular gap. A plurality of inlets open tangentially into this gap, upstream of the mouth of the first pipe to distribute cooling oil along the wall of the second pipe. The cooling oil film is found to be uniform and coherent and prevents contact of the cracking gas with the wall of this pipe. A further pipe opening axially into the surrounding pipe or pipe section sprays an additional quantity of cooling oil into the cracking-gas stream downstream of the mouth of the inlet pipe.
