ABSTRACT:
A process for producing carbon blacks without the use of a quenching liquid to stop pyrolysis of the effluent in the reactor. In the process of the present invention, the effluent passes from the reaction zone of a furnace carbon black reactor downstream into a lined wall heat exchanger where the effluent is sufficiently cooled to stop pyrolysis. The effluent may be pre-cooled before it enters the lined wall heat exchanger by a quench injecting fluid at a rate substantially lower than in a conventional process wherein all of the fluid is finely atomized in the effluent such that the duration of the presence of liquid phase in the effluent stream is substantially minimized. In a preferred embodiment a cleaning method is utilized to continuously remove deposits from the interior walls of the lined wall heat exchanger and/or the secondary cooler.
