Gas Scrubbers

Gas scrubbers are systems designed to remove harmful substances from industrial exhaust gases. These systems work by bringing polluted air or gas into contact with a washing liquid that absorbs contaminants such as acid gases, amines, and organic pollutants—effectively solving emission and odour problems.

With over 35 years of experience and references worldwide, our gas scrubbers are built for efficiency, low maintenance, and resistance to corrosion and heat. Thanks to their open, clog-free designs, our gas scrubbers ensure long-lasting performance and minimal downtime, even in harsh industrial environments.

How Gas Scrubbers Work

Gas scrubbers operate by introducing contaminated gas into a column where it comes into contact with a scrubbing liquid. This liquid, often combined with specific reagents, absorbs and neutralizes pollutants such as acid gases and other unwanted compounds. Our scrubbers feature advanced control mechanisms to ensure high removal efficiency and stable operation, with options for monitoring pH, conductivity, density, and other process parameters.

Our scrubbers are suitable for a wide range of applications, effectively handling corrosive gases, hot exhaust streams, and dust-laden emissions. Common use cases include the removal of:

H₂S – removal in biogas upgrading and sulfur recovery units

H₂SO₄ mist – removal in sulfuric acid production or chemical processing plants

HCl – removal from metal pickling lines, incineration gas, or chemical manufacturing exhaust

NH₃ – removal in fertilizer production, wastewater treatment, or animal rendering plants

VOCs – removal in pharmaceutical, paint, and solvent-based industries

SO₂ – removal in flue gas treatment from combustion or ore roasting operations
