OASE® blue - Solutions for Flue gas/industrial CO2

OASE® blue

From the very beginning, OASE® blue was developed specifically as an optimized large-scale post-combustion capture (PCC) technology. BASF supplies customers with a customized technology package along with highly stable, low-maintenance innovative solvent solutions for specific applications. With low energy consumption, low solvent losses and an exceptionally flexible operating range OASE® blue is the paramount technology for use in flue gas carbon capture from sources such as fossil power generation plants or steam turbines.



The power plant site in Niederaussem, Germany: This is where the joint research program for CO2 scrubbing by BASF, Linde and RWE Power started. CO2 scrubbing is a key technology for carbon capture and storage (CCS). The results achieved are remarkable: significantly reduced energy consumption, high purity of the captured CO2, low detergent consumption and a plant availability of 97 percent.

CO2 Capture For Utilization

BASF Gas Treating Excellence provides CO2 capture solutions that support applications ranging from enhanced oil recovery (EOR), urea production and small food grade CO2 production facilities. Further, the OASE® technology portfolio is complementary in meeting customer-specific applications. As a consequence, the benefit of implementing OASE® technology is a CO2 product available for commercial utilization.

Improving CO2 Capture with OASE® blue

Although commercially available, BASF continues the innovative deve­lopment of the OASE® blue process in a joint project with Linde. Testing is aimed at process optimizations to further reduce the levelized costs of electricity by a cut in the costs of CO2 capture. In 2011, the U.S. Depart­ment of Energy awarded the cooperation with US­15 million in funding.

Non-Aqueous Solvents

Starting in 2010, BASF joined with U.S. research institute RTI International to develop a new, exceptionally cost-effective technology to capture CO2. The development project is sponsored by a $2 million cooperative agreement from the DOE. The two partners are developing novel non-aqueous solvent systems that can be recycled and potentially use 40% less energy than conventional processes.
