Atlas Copco unit bags biogas upgrade pilot project

| 18/06/2012 | 0 Comments

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.

Although biogas upgrading to green gas has already a high efficiency compared with the production of electricity from biogas, Atlas Copco believes that it is possible to improve this high efficiency.

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.

The goals of the pilot project include: 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 (LBG).

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 with Cirmac’s trade name ‘CO2 Absorber LP Cooab’.

Horst Wasel, President of Atlas Copco Quality Air Division, said: “I am convinced that the final results and findings of this project will cope with our high expectations. These technologies will not only strengthen our leading position but also enable us to grow – together with this future oriented market segment.”

Cirmac is working on the project with Royal Haskoning Consulting, which will look after project management, monitoring plan and market investigation, and  Waterschap Veluwe, a wastewater treatment company, which will provide  the location and biogas for the pilot project.
