  • Method of desulfurizing waste gases containing sulfur dioxide
    Patent number: 4442083
    Abstract: Sulfur dioxide (SO.sub.2) is absorbed from waste gases by absorbing SO.sub.2 in an aqueous absorbent comprising soluble sulfite in an absorber; stripping the SO.sub.2 from the absorbent; absorbing the stripped SO.sub.2 in a separate absorbent for the SO.sub.2 ; and reacting the thus absorbed SO.sub.2 in a liquid Claus reactor forming sulfur. In a preferred embodiment, the gas from the stripping step is subjected to a condensation step in a heat exchanger boiler where steam ingoing to the stripper is generated.
