Abstract
A method of scrubbing hydrogen sulfide (H.sub.2S) from a gas stream employing a potassium-based sorbent to remove at least a portion of the H.sub.2S. This results in reaction products that are oxidized and converted into potassium-sulfur based fertilizers. The potassium based sorbent may be potassium hydroxide (KOH) made on site from potash. Hydrogen chloride (HCI) may be a byproduct when the sorbent is made from potash.
