Desulphurization Pump
Desulphurization Pump
Desulfurization pumps are a type of industrial pump specifically designed for use in flue gas desulfurization (FGD) systems. Flue gas desulfurization is a process used to remove sulfur dioxide (SO2) from exhaust gases produced by the combustion of fossil fuels, particularly in power plants. The removal of sulfur dioxide is crucial for environmental reasons, as it helps reduce air pollution and the formation of acid rain. Desulphurization pump are corrosion-resistant pumps, mainly used for the transportation of corrosive liquids. It is a widely used pump among general equipment pumps. The desulfurization pump is usually a horizontal cantilever single-stage single-suction centrifugal pump, which is specially designed and developed for transporting corrosive media containing fine particles. The flow material of the desulfurization pump is required to be wear-resistant and corrosion-resistant.
Our desulfurization pumps are constructed with materials that resist corrosion and abrasion, such as high-chrome alloys or other wear-resistant materials.
Specialized seals and sealing systems are employed to prevent leakage and ensure the efficient operation of the pump over an extended period.
Given the critical nature of the desulfurization process, our pumps are designed for high reliability and extended service life.
The pumps are engineered to handle the specific characteristics of FGD slurry efficiently, minimizing energy consumption and optimizing overall system performance.
Desulfurization pumps are designed with considerations for the density and composition of the slurry, as well as the operating conditions within the FGD system.
SGB offers a comprehensive selection of dredger pumps designed to meet the demanding requirements of the dredging industry. Our products are built to handle a wide range of slurry pumping applications, including dredging, sand and gravel extraction, mining, and more.
Our Desulphurization pumps are specially designed to handle high-pressure slurry pumping applications, including the transportation of corrosive and abrasive materials. They are ideal for use in power plant desulphurization processes, where they can effectively pump limestone slurry and other abrasive materials.
Our Sludge Recirculation Pumps are designed to handle the transfer of sludge from one location to another, making them ideal for use in wastewater treatment plants, chemical processing facilities, and other applications. They are built to handle high volumes of sludge and are available in a variety of sizes and configurations to meet the specific needs of your application.
Whether you need a Desulphurization Pump, a Sludge Recirculation Pump, or any other type of dredger pump, SGB has the solutions you need to get the job done right. Contact us today to learn more about our products and services.
In a flue gas desulphurisation system (FGD), sulphur compounds are removed from the exhaust emissions of fossil-fuelled power stations. This is done by means of an industrial process through the addition of absorbents. This can remove up to 95 % of the sulphur dioxide from the flue gas, since the current threshold value for SO2 in the EU is 200 mg/Nm3 (Nm3 = normal cubic metre).
The wet process has become the main method of flue gas desulphurisation in large, fossil-fuelled power plants. In this method, the flue gases are steam-saturated with the absorbent in aqueous solution. Substances such as ammonia or sodium sulphite are used as absorbents; however the use of lime or limestone slurry (wet limestone scrubbing) is also widespread. The uncleaned flue gas is sprayed in a scrubber tower (absorber tower) with a mixture of water and limestone (scrubbing slurry), whereby most of the sulphur dioxide is bonded by chemical reaction.

After a number of chemical reactions, gypsum is finally produced in a suspension. After dewatering, this leaves gypsum with up to 10 % residual moisture, which provides a valuable product for the construction material industry.
The pumps used in the individual process stages are absorber circulating pumps (scrubber pumps, which - because of the high solids content and the aggressiveness of the fluid handled - are designed as non-clogging impeller pumps with special lining) and FGD auxiliary pumps (for lime
and gypsum slurries in duplex materials).
