Linde LLC (Linde), along with BASF and the Electric Power Research Institute, will design, build, and operate a 1 megawatt electrical (MWe) equivalent slipstream pilot plant at the National Carbon Capture Center (NCCC) to further refine a post-combustion capture solvent technology developed by Linde and BASF. The technology incorporates BASF’s novel amine-based solvent, OASE® blue, along with Linde’s process and engineering innovations. The post-combustion capture technology offers significant benefits compared to other solvent-based processes with the capability to reduce regeneration energy requirements by using novel solvents that are stable under the coal-fired power plant feed gas conditions. The project objectives are to design and build the 1 MWe pilot plant; conduct parametric testing to confirm that the pilot plant meets the performance targets and to obtain appropriate design information; perform a detailed data analysis to assess and develop the design basis for scale-up; and operate the pilot plant continuously under stable conditions to confirm the solvent stability and key material compatibility. The long-term test results will be used to update a techno-economic analysis for a 550 MWe coal-fired power plant incorporating the novel amine-based post-combustion CO2 capture technology and confirm that it can meet the Department of Energy’s carbon capture performance goals.
This project focuses on process intensification along with BASF’s novel amine-based solvent. The solvent provides significant reduction in regeneration steam consumption, electrical power, and cooling water, and is readily scalable to large capacities with a single-train system, further reducing capital and operating costs. Specifically, this project will design and build a 1 MWe pilot plant and conduct long term testing to validate solvent stability.
