Abstract

An apparatus for effecting direct quench of pyrolysis furnace effluent. A quench tube sized somewhat larger in diameter than the furnace effluent pipe is provided with an upper inverted ring and an external housing surrounding the terminus of the furnace effluent pipe, the quench tube and the inlet to the transfer pipe. The housing includes a chamber for quench oil, insulation space and purge gas space. In operation, quench oil is introduced continuously into the housing chamber and over the lip of the inverted ring to flow continuously down the sides of the quench tube inner wall.
