ABSTRACT:
A method and apparatus are provided for producing carbon black wherein in a carbon black reactor a first quench of effluent flowing through a quench zone is effected by contact of the effluent with water. The first quench cools the effluent to a temperature sufficiently low to stop pyrolysis. Downstream of the first quench is a secondary quench in which cooled smoke ahead of the filters is contacted with the effluent for secondary cooling the effluent. After the second cooling the effluent flows to an indirect heat exchanger wherein the effluent is again cooled, by indirect contact with a coolant in the heat exchanger, to a temperature sufficiently low to prevent damage to the filter system.
