摘要： A method and apparatus for treating waste gas for an solvent-based carbon capture unit. The process involving the use of a dry sorbent injection (DSI) unit to remove sulfur compounds and fine particulate matter from flue gas are described. The treated flue gas is used to preheat the rich solvent stream from the carbon capture unit. Flue gas from an FCC regenerator, for example, is used to make superheated steam and saturated steam. The process allows for increased thermal energy recovery, decreased water utility and increased equipment reliability.
