  • Utilization of combustible components of a tail-gas in the manufacture of carbon black at a high production rate
    Patent number: 4261964
    Abstract: The present invention provides an effective means of increasing the production rate of a carbon black process. A hydrocarbon fuel is burned in an insufficient amount of air to support complete combustion to produce a hot gas mixture which produces a tail-gas containing carbon black by the incomplete combustion of a hydrocarbon feedstock. This tail-gas is quenched, the carbon black is removed, and the tail-gas is dried. One or more of the combustible components are removed from the dried tail-gas and from 33 1/3% to 100% of the fuel is replaced with the combustible components so removed.
