Wet scrubbing for So2 removal in industrial applications
In heavy industries that generate significant amounts of flue gas, controlling sulfur dioxide (SO2) emissions is critical to meet environmental regulations. Traditional methods may fall short in effectiveness, creating a need for a more reliable and efficient solution.
Effective So2 removal with limestone scrubbers
The wet scrubbing solution from GEA is specifically designed to remove SO2 and other acid components from flue gases in a highly efficient manner. This limestone-based flue gas desulfurization (FGD) system uses a slurry of limestone to absorb and react with the SO2 present in the gas stream, converting it into gypsum. The scrubber operates as a spray tower without internal structures and benefits from a counter-current flow, which enhances contact between the gas and the scrubbing liquid. This setup ensures high reliability and excellent removal efficiency. It is particularly applicable in industries such as cement manufacturing and power plants. The limestone scrubber can be constructed from materials like stainless steel, FRP, or rubber-lined/coated carbon steel. The generated gypsum can be reused in cement plants or to fabricate plasterboards, further adding value.
