Wet scrubbers for acid gas absorption
Effectively capture and neutralize harmful acid gases with advanced wet scrubbers, ensuring seamless emission control and cleaner industrial processes.

Removes Acid Gases and Industrial Fumes
The Sorpt.X SW from Dürr is designed to efficiently control acid gas emissions across various industries, including chemical, pharmaceutical, and automotive sectors. This wet scrubber operates by exposing acid gases to an alkaline agent to form stable salts, ensuring easy removal. It features different configurations such as spray, tray, and packed towers, offering flexibility in handling varying gas volumes and concentrations. The Sorpt.X SW’s low pressure drop design, with typically less than 2 in. w.g., is crucial for retrofitting, especially where process fans have limited capacity. It boasts high removal efficiencies for SOx, HF, and HCl, while requiring minimal maintenance due to its non-clogging atomizing nozzles. Constructed with materials that resist corrosion, it maintains performance even in harsh conditions. Configurable to fit both vertical and horizontal setups, the Sorpt.X SW ensures seamless integration into existing systems, supported by Dürr’s engineering expertise for tailored solutions.
