A compact, economic scrubber to improve farm biogas upgrading systems

Farm-scale Biogas Plants

In Germany there are about fifteen years of experience in the planning and construction of farm-scale biogas plants. In the meantime, approximately 1,600 biogas plants are in operation on farms. This is primarily due to investment funding and payment for each kWh delivered to the public energy grid. In general, three different kinds of digester types are in use for anaerobically treating manure...

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 ...

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,...
