Simulation of Fixed-Bed Adsorption for Biogas Upgrading

Biogas Upgrading by Pressure Swing Adsorption

Operational Study and Simulation of a Biogas Upgrading Plant

Samson O. Masebinu, Akinwale O. Aboyade, Edison Muzenda Abstract-The drive for finding alternative energy to supplement fossil based fuel within the South African energy sector has led to research on waste to energy in particular biomethane as vehicular fuels. Biogas is produced from the anaerobic decomposition of organic matter with 40-70% vol. of methane. Biogas if upgraded, by removing the n...

Modeling and Simulation of Fixed Bed Adsorption Column: Effect of Operating Variables

The kinetics in a fixed-bed adsorption system is explained using a mathematical model that takes into account of external and internal mass-transfer resistances with a nonideal plug flow behavior. The variation of fluid velocity along the column is an important aspect, which has not been accounted so far in these models. In the present study, a mathematical model is proposed for explaining the ...

Selected Methods of Advanced Biogas Upgrading

The upgrading of biogas for the production of biomethane to be injected to the natural gas grid has gained significant importance in recent years. It is often considered to be superior to the production of electricity and district heat with internal combustion engines mainly because of better energy utilisation, higher flexibility and beneficial economic prospects. Biogas upgrading is commonly ...

Elimination of siloxanes by adsorption process as a way of upgrading biogas

Biogas is increasingly being investigated as a source of renewable energy, however its utilisation requires an improvement of its quality. Certain biogases contain compounds called siloxanes; these compounds are the origin of some problems when using biogas. At high temperatures siloxanes are transformed to silicate oxides which can damage equipment (i.e. engines corrosion, the clogging of fuel...
