Abstract
Gaseous components are removed from gas streams and chemically converted into an insoluble phase in a liquid medium. Specifically, hydrogen sulfide is removed from gas streams by oxidation in aqueous chelated iron hydroxide solution in a modified agitated flotation cell. A combined chemical reactor and solid product separation device comprising such modified agitated flotation cell also is described. In order to effect efficient mass transfer and rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 300 in/sec. to achieve the required shear. To assist in the reaction, a surrounding shroud has a plurality of circular openings of equal diameter and arranged in uniform pattern such as to provide a gas flow therethrough less than about 0.02 lb/min/opening in the shroud. Each of the openings has a diameter less than about one inch.
