HYDROGEN SULFIDE REMOVAL FROM BIOGAS BY SULFUR OXIDIZING BACTERIA UNDER MICROAEROPHILIC ENVIRONMENT IN THE ANAEROBIC DIGESTER

Modeling and Removal of Hydrogen Sulfide from Biogas Produced by Anaerobic Digestion

Anaerobic digestion can be used to convert organic waste into energy not only to provide renewable energy, but also reduce greenhouse gases. During the anaerobic digestion process, biogas is produced, which can be used for heating and electricity generation. The produced biogas contains methane and some other gases, the most destructive of which is hydrogen sulfide gas. If hydrogen sulfide gas ...

Selection of sulfur oxidizing bacterium for sulfide removal in sulfate rich wastewater to enhance biogas production

Removal of Hydrogen Sulfide from Biogas Using Cow-manure Compost

The two-part objective of this study was to determine currently available H2S removal technologies suitable for use with farm biogas systems, and to test the feasibility of utilizing on-farm cow-manure compost as an H2S adsorption medium. Integrated farm energy systems utilize anaerobic digesters to provide a waste treatment solution, improved nutrient recovery, and energy generation potential ...

Hydrogen sulfide removal from biogas using chemical absorption technique in packed column reactors

The toxicity and corrosion potential of hydrogen sulfide in raw biogas underlines the need for biogas purification. Several techniques available for removal of hydrogen sulfide from biogas are out of the reach for common end users due to lack of knowledge, higher running costs, and insufficient operational skills. The present experimental study aims to propagate hydrogen sulfide removal techniq...
