ENGINEERINGNET.EU -- Cirmac International bv, part of Atlas Copco Group, was recently awarded for the project "High efficiency Low Pressure CO2 Absorber LP Cooab". The presented solutions will offer environmental friendly and cost efficient upgrading of biogas to higher qualities.
One of the ambitions of the Dutch government is to achieve 20% of the energy supply being sustainable in 2020. In this framework the department Energy and Climate of Agentschap.nl, invited companies to propose projects to make the fermentation chain more effective and efficient.
The goals of the pilot project were clearly defined: reduction of the green gas cost price, lower environmental impact by reducing CO2 emission, reduction of the system energy consumption and efficient biogas upgrading to higher qualities in order to gain Liquified Bio Gas.
The LP Cooab technology is based on low pressure reversible chemical absorption, specifically designed to remove CO2 from biogas. An essential element in this process is the absorption liquid, in this case a special amine composition.
Cirmac is realizing the project together with Royal Haskoning Consulting, responsible for project management, monitoring plan and market investigation, and with Waterschap Veluwe, a waste water treatment company which supplies the location and biogas for the pilot project.
BACKGROUND
Biogas upgrading is the starting point to bring biomethane to end users. Anaerobic digesters typically produce the raw gas from organic materials and waste. CO2 is extracted from the raw gas to obtain Methane. During this process, undesired inert and corrosive substances are removed. Biogas upgrading equipment is specifically designed to cope with the raw gas composition at your site.
