  • Process for production of carbon black
    Patent number: 7655209
    Abstract: Off-gas from a carbon black furnace is employed as a combustion gas feed stream to the burner or combustion zone of the same or a different carbon black furnace in accordance with certain embodiments, suitable conduit and valving is provided to pass off-gas, from which carbon black has been substantially removed, from any and all of multiple different carbon black furnaces to the burner. The off-gas is heated, preferably by plasma heating, and dewatered. Carbon dioxide stripping or rather stripping of gas components from the dewatered heated off-gas is found to be unnecessary to achieve economically favorable use of off-gas recirculation.
    Type: Grant
    Filed: May 28, 2008
    Date of Patent: February 2, 2010
    Assignee: Cabot Corporation

  • Carbon black tailgas fueled reciprocating engines
    Patent number: 6349678
    Abstract: A system and process for utilizing tail gas from a carbon black manufacturing process as a fuel in a reciprocating engine. The tailgas is dewatered and mixed with air to form a fuel gas. The fuel gas is pressure charged and then ignited in the reciprocating engine to derive useful work.
