Akermin Pilot Captures 90% CO2
Akermin says it has successfully tested its Biocatalyst Delivery System at the National Carbon Capture Center in Wilsonville, Ala. The pilot unit (pictured) has operated continuously for several weeks capturing close to 90 percent CO2 from flue gas with significant rate enhancement and no degradation in performance, the cleantech company says.
Akermin CEO Barry Blackwell says this marks the longest and largest demonstration of an enzyme-catalyzed process for CO2 capture.
The project was partially funded through a grant from the US Department of Energy. Project partners and suppliers include: Novozymes, EPIC Systems, Battelle and the Pacific Northwest National Laboratory, Blackwell says.
The pilot plant will continue operations for several months with no replenishment of enzyme. The operating data provide technical and economic validation for CO2 removal from target markets such as biogas upgrading, LNG and ammonia production and support larger-scale field pilot testing for natural gas and coal-fired power plants, the company says.
Akermin has developed a next-generation approach using an environmentally friendly salt solution and proprietary process scheme that enables on-line biocatalyst replacement. The company says this technology will be demonstrated in future projects and can be applied to further reduce the cost of CO2 emissions reduction for large-scale industrial operations and natural gas and coal-fired power plants.
The company says it is seeking partners to support commercialization of this technology.
Akermin’s CO2 capture test follows several projects in recent months aimed at managing CO2 emissions from industrial processes.
Last month, Aker Solutions won a contract to perform the world’s first tests for capturing carbon dioxide emissions from a cement production plant.
Also in May Air Products announced it was operating a Department of Energy demonstration project that will capture about 1 million tons of CO2 in an enhanced oil recovery project in Texas.
