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.
Key Features of Our Desulphurization Pump
Material Resistance
Our desulfurization pumps are constructed with materials that resist corrosion and abrasion, such as high-chrome alloys or other wear-resistant materials.
Sealing Mechanisms
Specialized seals and sealing systems are employed to prevent leakage and ensure the efficient operation of the pump over an extended period.
Reliability
Given the critical nature of the desulfurization process, our pumps are designed for high reliability and extended service life.
Efficiency
The pumps are engineered to handle the specific characteristics of FGD slurry efficiently, minimizing energy consumption and optimizing overall system performance.
Design Considerations
Desulfurization pumps are designed with considerations for the density and composition of the slurry, as well as the operating conditions within the FGD system.
We 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.
Pump Materials for Wet Flue Gas Desulfurization
A cement factory in Texas was among the first in the U.S. to install wet flue gas scrubbers in order to reduce the sulfur dioxide emissions. This is a demanding application for pumps because the gypsum slurry that “scrubs” the gas is highly abrasive and corrosive.
Special pump systems with housings and impellers made of mineral cast proved to be an ideal solution for this specific application.
Wet flue gas desulfurization scrubber systems can be vital components in various industries due to strict environmental regulations of those applications. First applications were coal-fired power plants and waste incineration plants. Today, other industries use wet scrubbers in their day-to-day operations as well to scrub flue gas emissions from burners that use coal as a fuel source.
Slurry ‘Scrubs’ Toxins from Flue Gas
The scrubbers remove toxins from coal- fired flue gas streams in the process.
This is accomplished by spraying a mixture of limestone slurry over incoming flue gas. This creates a chemical reaction that removes or “scrubs” the toxins from the flue gas. Once the limestone slurry reacts with the incoming flue gas, it is converted to a gypsum slurry.
The gypsum is then dewatered and can be sold to end users for use in various industries. Concrete manufacturers are able to use the dewatered gypsum in the concrete production process.
Pump Housing Materials
The selection of pumps for this application is a crucial task.
Due to its significant corrosive and abrasive characteristics, gypsum slurry is a very difficult medium to handle. An American cement plant with a yearly capacity of about 2 million metric tons has found a good solution for that issue when it installed the first of two scrubber systems in 1998.
The housings of the eight pumps in the limestone slurry cycle are not made from metal materials, but from a special material that was designed specifically for extremely harsh conditions. This material is a mixture of silicon carbide (SiC) and epoxy resin that is poured into precision molds and heat cured to form the pump components. The material must be machined with diamond tools due to it exhibiting a hardness close to that of diamonds. The material is completely impervious to corrosion and exhibits extreme abrasion resistance given its metallic-free composition and high hardness value.
The scrubber recycle pumps in this plant have operated at a flow rate of 1,310 cubic meters per hour (m3/h), 21.1 meters (m) of head and 630 revolutions per minute (rpm) for nearly 20 years, requiring minimum attention and service. Of course, the mechanical seals were exchanged from time to time. Apart from that, four impellers, one casing cover and some minor components were replaced. An additional 24 pumps are installed in the second scrubber system and other applications in the plant.
Pumping in Extreme Conditions
This installation is a true testament to the superior performance of these pumps in the harshest environments. It shows why this type of pump is installed not only in this cement factory, but also in wet flue gas desulfurization systems in multiple power plants and other industrial facilities all across the world.
The pumps are not restricted to flue gas desulfurization. They are also used in processes such as ammonia phosphate and titanium dioxide (TiO2) pigment production, salt solution mining, sugar beet processing and sea water desalination.
