ABSTRACT:
A start-up technique for a carbon black production process, in which carbon black laden effluent smoke from a carbon black furnace is quenched to terminate the reaction and cool said smoke and said smoke is thereafter cooled, at least in part, by indirect heat exchange with water, in which the smoke is initially quenched with a quench fluid to a temperature substantially below a predetermined temperature of introduction into the heat exchange step and the magnitude of the quenching is reduced over an extended period of time until the smoke is being quenched into a temperature substantially equal to the predetermined temperature.
