Common desulfurizers available on the market include various types such as iron oxide and lime-based ones, which are widely used for industrial waste gas and raw material purification. The specific choice depends on the treatment target. In simple terms, a desulfurizer is a chemical agent used to remove sulfur compounds from fuels, raw materials, or waste gases, such as removing sulfur dioxide from flue gas or hydrogen sulfide from natural gas, to prevent pollution and equipment corrosi.

Environmental governance: Flue gas desulfurization in coal-fired power plants, waste incineration plants, and coking plants to ensure emissions meet standards, with the limestone-gypsum method being the most widely used.

Energy purification: Natural gas stations, oil refineries, and biogas projects prevent hydrogen sulfide from corroding pipelines and equipment, while meeting pipeline transportation standards.

Metallurgical and Chemical Industry: Iron and steel plants conduct hot metal pretreatment to reduce the sulfur content of steel and improve its quality; chemical plants treat sulfur-containing tail gas to recover sulfur resources.

Civil use and boilers: Small industrial boilers or civilian stoves can control sulfur dioxide emissions by adding sulfur-fixing briquettes or specialized chemicals.
