Figures 2 show the corrosion produced in different parts of the cogeneration system by the presence of H2S in the biogas. Figures 2. Corrosion in the recuperator, silencer and piston due to the presence of H2S in the biogas. ...
The composition of the biogas depends entirely on the nature of the waste used and the conditions under which anaerobic digestion is carried out. Generally, the biogas is used for energy recovery, which is determined by the methane concentration. However, a purification of certain contaminants with abrasive and corrosive character, such as siloxanes and ...
Fluence technology scrubs hydrogen sulfide from biogas before it's used to generate electricity. The Fluence biogas desulfurization system installed at the Citrusvil plant uses four washing columns as well as two oxidation tanks. Citrusvil, a large, South American citrus-processing company, has a focus on building sustainability into its production systems. This extends to using waste-to-energy ...
As we have found here at Base, the long term credibility and hence success of any good company relies on the employment and retention of key staff. Steve Price, H2 Energy Chief Technical Officer is a good example of this. Base first partnered with Steve on the Alderley Edge biogas project where he was an early investor in the Base Gas Holder system which he used ...
A farm-scale biogas desulfurization system was designed and tested for H2S removal efficiency from livestock biogas. ...
Conventional sewage treatment: Sludge line: 20 kg DM IE year to sludge; 1.500.000 tons sludge per year Sludge treatment and disposal: 40% of STP opex average cost € 330 / ton sludge (incl. dewatering and processing costs) Traditional (mesophilic ) sludge digestion: Prim. sludge / sec. sludge = 50 : 50 Hydraulic Retention Time 20 days Average yield: 25 – 40% ...
During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid (H2SO4). It is for this reason that the level of ...
The best yield was obtained in the last period where a specific hydrogen production of 50.9 L/kg VSfed was reached, with a H2 content in biogas from the first reactor of 36%. The methanogenic stage after the hydrogen conversion reached a specific biogas production of 0.62 m3/kg VSfed and an overall organic removal above 70%, without any stability ...
The microaerobic removal of H2S was studied to determine the treatment capacity at low and high H2S concentrations in the biogas (0.33 and 3.38% v/v) and to determine the optimal O2 rate that achieved a concentration of H2S of 150 mg/Nm3 or lower. ...
