Wet scrubbing for So2 removal in industrial applications
Effectively eliminate sulfur oxides from flue gases using advanced wet scrubbing technology, ensuring cleaner emissions and transforming pollutants into valuable gypsum for construction materials.
Removes SO2 and Produces Gypsum
The Limestone Wet Scrubbing System offers a robust solution for sulfur dioxide (SO2) removal from industrial flue gases. By employing a limestone-based wet flue gas desulphurization (FGD) process, this system is particularly effective for large-scale applications in cement plants, power stations, and metal smelters. Its scrubbing mechanism operates through a counter-current flow in a spray tower, facilitating the absorption of SO2 and subsequent production of gypsum, a byproduct that can be used in cement manufacturing and plasterboard production.
The system is versatile, accommodating various materials such as stainless steel and rubber-lined carbon steel, ensuring durability and resistance to corrosive elements. It integrates seamlessly into existing operational lines and is adaptable for both small and large volumes of flue gas.
With continuous operation and manual control, the system maximizes efficiency, featuring adjustable parameters to maintain optimal SOx removal even under varying dust and contaminant levels. Furthermore, it includes a reliable dewatering system that minimizes gypsum moisture content to approximately 10%, ensuring easy handling and disposal. This equipment not only enhances environmental compliance for industrial facilities but also contributes to sustainable production practices by transforming waste into valuable resources.
