The Thiopaq Process - Video
The THIOPAQ® was developed by Paques, in cooperation with universities, research institutes and customers. It can be applied to a wide range of biogas streams containing H2S and can be combined with all biological anaerobic systems. The ‘caustic’ solution in the THIOPAQ® scrubber is continuously biologically regenerated. In the scrubber, the gas containing H2S is brought into contact with the washing water in counter currently. Absorption of H2S under slightly alkaline conditions (pH 8-9) enables a chemical reaction with hydroxide ions.
