  • Method for removing sulfur dioxide from flue gases
    Patent number: 4666690
    Abstract: A method for removing sulfur compounds from flue gases in which a slurry of calcium oxide and water is formed and exothermically reacted to form a hydrate containing calcium hydroxide in substantially saturated solution. The calcium hydroxide is converted to relatively fine particles as the saturated liquid is flashed to steam. The fine particles are passed in a counter-flow relationship with the flue gases so that the sulfur compounds from the flue gases react with the calcium hydroxide in the particles to form calcium sulfate.
