  • Process for energy recovery in carbon black production
    Patent number: 10723964
    Abstract: A combustible gas from carbon black production is utilized in a gas engine by adding an oxygen-containing gas to the combustible gas, passing said mixed gas over a selective catalyst, which is active for oxidizing H2S to SO2 but substantially inactive for oxidation of CO, H2 and other hydrocarbons with less than 4 C-atoms, passing the converted gas through an SO2 removal step, and passing the cleaned gas to a gas engine or to an energy recovery boiler. This way, the tail gas from carbon black production, which is normally combusted in a CO boiler or incinerated, can be utilized to good effect.
