Groot Zevert Vergisting
Frames designed and supplied a biogas upgrading installation which can effectively remove H2S from the biogas to below 3 ppm level. The installation thereby protects compressors and other critical parts of the biogas upgrading plant from corrosion. Furthermore it enables Groot Zevert Vergisting to inject the upgraded biogas into the pipeline to transport the gas to the world’s largest dairy co-operative FrieslandCampina.
The biogas upgrading installation will facilitate the delivery of 8 million cubic meters of biogas a year to the FrieslandCampina establishment in Borculo, The Netherlands. FrieslandCampina will use the gas for the production of steam.
Small ecological footprint
This project fits the climate-neutral growth objectives of both the Agricultural Sector and the Paris Agreement. Frames is therefore very proud of their contribution to this project. “We develop innovative technologies and feel it is our responsibility to offer sustainable solutions for energy production with a small ecological footprint,” says Nick Ten Asbroek, Sales Manager at Frames Renewable Energy Solutions. “This project and the Frames LAMINOL® technology we integrated in the installation, proofs our know-how and ability to successfully innovate the energy and biogas market with smart and cost-efficient solutions.”
H2S removal required
Hydrogen sulfide (H2S) is a very toxic and corrosive gas that causes problems in both the upstream and downstream oil and gas industry as well as biogas plants, like Groot Zevert Vergisting. Completely eliminating H2S upfront of further biogas handling reduces corrosion, safety and operational expenditures significantly in the rest of the biogas utilization installation. Frames uses a new solution for this H2S removal, which is one of a kind in the energy and biogas market.
“The Frames LAMINOL® H2S technology that is used at the Groot Zevert Vergisting installation is a cost-effective alternative to conventional biogas sweetening processes such as impregnated active carbon or solid dry bed processes to prevent hydrogen sulfide corrosion,” explains Ten Asbroek. “The LAMINOL® technology is capable of selectively removing H2S from CO2 rich gas streams to a few ppm level even at near atmospheric gas pressure.”
The regenerative LAMINOL® version Frames delivered at Groot Zevert Vergisting employs a biodegradable and safe scrubbing fluid that selectively react with H2S. By regeneration of the fluid with air in a regeneration reactor elementary sulfur is produced which is separated concentrated and can be employed as sulfur fertilizer.
