Oregon Plans To Open Biogas Plant On Dairy Farm

Plans have been revealed to construct a biogas upgrading plant, which will need a lot of tank blanketing valves to function effectively, on a dairy farm in the US.

Wartsila’s Puregas Solutions will develop the biogas upgrading plant in Oregon, and has signed a contract to update an anaerobic digester that already exists on the site so that it can produce biomethane.

It is thought the plant will help the dairy facility reduce its methane emissions significantly once it is running, processing 3,100 cubic feet per minute of biogas from the anaerobic digestion of manure as there are more than 50,000 dairy cows on the farm.

Around 81 mmBTU of biomethane will be produced from the site per annum, which is enough to provide energy for more than 15,000 households for an entire year.

A pipeline will be installed at the facility so the fuel can be transported to California and used in the neighbouring state.

Managing director of Puregas Solutions Jan Molin said: “This project, which essentially converts the methane gas from animal manure into a sustainable transportation fuel, is environmentally significant and an indicator perhaps of a future trend in biogas upgrading in the agricultural industry.”

She added the company managed to secure the contract thanks to its technological advancements in turnkey solutions.

This comes after Wessex Water handed in its proposals to construct a biogas plant on an existing sewage treatment site just outside Bournemouth.

The Bouremouth Echo reported the water company wants to input the gas into the national grid so the energy can be used by the public.
