H2S
What is H2S ?
Wastewater streams contain different amounts of sulfur compounds. Under atmospheric conditions – in the presence of oxygen – the sulfur is mainly bound as sulfate (SO4) and dissolved in the wastewater.
In the anaerobic digesters the organic matters are degraded by anaerobic bacteria. In the absence of oxygen the sulfate is converted to hydrogen sulfide (H2S) which is a gas.
Thus, after the anaerobic digestion process, the sulfur compounds present in the inlet stream leave the reactor through the biogas as H2S. Typically the H2S in the biogas will be in the range from 0.1% to 3.0% (1,000-30,000 ppm).
We look forward to meeting you!
Please contact us if you need an efficient solution for desulfurization or methanation of biogas or CO2. We can help you for any flow of biogas or CO2 flow and H2S load no matter if your project is greenfield or refurbishment of an existing plant. We will be happy to share our experience with you and find an optimal solution for your needs.
