Special Issue "Advances in Biogas Desulfurization"
A special issue of ChemEngineering (ISSN 2305-7084).
Deadline for manuscript submissions: closed (30 April 2019)
The use of biogas is increasing in an effort to reduce the consumption of non-renewable energies. Biogas is an interesting renewable energy sources produced by the biodegradation of organic matter under anaerobic conditions. Its composition depends on the feedstock type and digestion system. Biogas is a gas rich in methane and carbon dioxide, however, numerous other compounds are also found, such as hydrogen sulfide, ammonia, volatile organic compounds, etc. For all applications (heat and power production, injection into natural gas grid, fuel for solid oxide fuel cells, biogas reforming, vehicle fuel, etc.) the hydrogen sulfide concentration needs to be reduced because its produces corrosion, damages equipment and sulfur dioxide emissions in biogas combustion.
Biogas desulfurization methods can be classified into two generic categories: Those involving physicochemical phenomena and those involving biological processes. The physicochemical techniques can be divided into two types process: Wet processes (ion-based chelation processes, alkanolamine scrubbers, etc.) and dry processes (ion-sponge, impregnated active carbon, etc.). Biological processes, are mainly carried out by biotrickling filters and bioscrubbers. Although it also can be supplied with air or oxygen for the anaerobic digesters to produce elemental sulfur under microaerobic conditions.
This Special Issue is open for all contributors in the field of biogas desulfurization. This Special Issue aims to bring together scientific/technical advances on physicochemical and/or biological processes for biogas desulfurization. Biogas desulfurization is seen as essential by many stakeholders (biogas producers, suppliers of biogas upgrading devices, gas traders, researchers, etc.) around the world, who knows the importance of biogas desulfurization to allow its valorization. International contributions to this Special Issue will show the latest advances in desulfurization processes.
