Desulfurization | Biogas-Consult
Desulfurization. Anaerobic microbial degradation of organic substances in biogas facilities produces not only the principal components methane CH 4 and carbon dioxide CO 2, but also hydrogen sulfide H 2 S. Among other things, the hydrogen sulfide concentration in the biogas is dependent on the substrates used, and can range from a few ppm in facilities processing renewable resources to ...

Review of desulfurization process for biogas
Hydrogen sulfide H 2 S is a toxic and odorous compound present in biogas produced by the anaerobic digestion of biosolids and other organic materials. Elimination of H 2 S is necessary as it is extremely hazardous to human health, poisonous to process catalysts and corrosive to equipment. The desulfurization technology is an important part for efficient utilization of biogas.

Desulfurization of Coal
2017-1-16In coal combustion, to generate electric power and process heat, the sulfur is emitted as SO2, which is seen as one of the main causes of acid rain. This effect has led to an interest in the three main methods of removing coal sulfur coal cleaning, in-bed desulfurization, and flue gas desulfurization. Coal cleaning includes physical, chemical,
Wet flue gas desulfurization principle
2015-1-92 process Wet flue gas desulfurization process is varied, but they also have similar things in common the pretreatment of the flue gas sulfur e.g., cooling, humidifying, dust, absorption and oxidation, rich fluid handling grey water treatment, mist gas water
MDEA desulfurization process was adopted in a high sulfur natural gas purification plant in Sichuan and Chongqing gas field. Serious corrosion and liquid blocking foaming problems occurred in the daily production and operation of the plant, which eventually led to the shutdown of the unit.
Biogas desulfurization using autotrophic
The aim of this study was to evaluate the performance of an autotrophic denitrification process for desulfurization of biogas produced from a chicken manure digester. A laboratory scale upflow fixed bed reactor UFBR was operated for 105 days and fed with sodium sulfide or H2S scrubbed from the biogas and nitrate as electron donor and acceptor, respectively.

What is Desulfurization with pictures
2020-6-26Jeri Sullivan Last Modified Date 26 June 2020 . Desulfurization is the process of removing sulfur from something to prevent contamination. Also known as hydrodesulfurization or HDS, this chemical process reduces the sulfur dioxide emissions and converts them to sulfuric acid. The sulfuric acid is then used in car batteries and fertilizer.
