Biogas desulfurization
Thread Content
To carry out biological desulfurization of biogas, it is necessary to add a certain amount of air to the biogas; however, there is concern that the biogas might explode during combustion, and it’s not clear what level of oxygen is appropriate There was a refinery exhaust project that was given up as well, due to fears of explosions. Let the experts discuss this!
I’m not sure what the biological desulfurization process used by the original poster is like; in the biological desulfurization of biogas that I’ve worked on before, there was no issue of air getting mixed in.
Adding air to biogas carries a very high risk factor, and no one can guarantee that no problems will arise. The original poster, give up
I work in biological deodorization now; sometimes the hydrogen sulfide concentration is very high, and sulfur can be seen on the packing material. I want to introduce some air into the biogas; by using a biological filter, hydrogen sulfide can be removed. The key is to control the amount of air; when there is insufficient oxygen, hydrogen sulfide should be oxidized to elemental sulfur. In this way, when there is an excess of oxygen, it can still be oxidized to sulfurous acid, providing buffering effect. I used to think about it due to safety concerns, but after seeing a foreign company do it recently, I want to give it a try again. I hope everyone will give more suggestions.
