In-situ biogas upgrading process: Modeling and simulations aspects

Biogas upgrading technologies – developments and innovations

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 ...

Biogas Upgrading by Pressure Swing Adsorption

3. Upgrading Dairy Biogas to Biomethane and Other Fuels

Dairy biogas can be combusted to generate electricity and/or heat. This report, however, focuses on alternate uses of biogas including the upgrading of biogas to biomethane, a product equivalent to natural gas or other higher-grade fuels. Biomethane, which typically contains more than 95% CH (with the remainder as CO 4 2), has no technical barrier to being used interchangeably with natural gas,...

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...
