Biox®Bioscrubber 2500m3 Biogas Desulphurization Installation

Capacity: 2500m3

Maximum design flow was 2000m3, minimum design flow was 1000m3. Maximum H2S concentration was 7500ppm H2S. It was designed to reduce the H2S down to <100ppm.

Hydrogen sulphide (H2S) removal from biogas with efficiencies above 99%, minimizing maintenance costs. The equipment uses two treatment stages. The first stage is a scrubber, where the H2S contained in the biogas is transferred to an aqueous phase. The second stage is a liquid phase bioreactor, where solubilized H2S is oxidized mainly to elemental sulphur.
