H2S (hydrogen sulfide) scrubber refers to a device or system used to remove hydrogen sulfide (H2S) gas from a process stream. H2S is a toxic and corrosive gas that is often present in various industrial processes, such as oil and gas production, petrochemical processing, and wastewater treatment.
H2S scrubbers typically use chemical reactions to convert H2S into a less hazardous compound, such as elemental sulfur or sulfate. The most common chemical used for this reaction is caustic soda (sodium hydroxide), which reacts with H2S to form sodium sulfide. Other chemicals, such as iron oxide, may also be used in H2S scrubbing systems.
