The Linde Group (formerly BOC Group, Inc.) will conduct pilot-scale
testing of their Ceramic Autothermal Recovery (CAR) oxygen (O2) generation process integrated with a coal-fired combustor to produce a carbon dioxide (CO2) rich flue gas. The CAR process uses the O2 storage properties of perovskites to adsorb O2 from air in a fixed bed and then release the adsorbed O2
into a sweep gas, such as recycled flue gas, that can be sent to the
furnace. As shown in the figure below, the process is made continuous
by operating multiple beds in a cycle.
The project includes integrated testing of a 0.7-ton O2 per day unit at Western Research Institute (WRI) and scale-up to a 10-ton O2
per day unit and integrated testing at Alstom. Linde will complete
integration of the CAR unit dual bed system with the Combustion Test
Facility at WRI to conduct integrated oxy-combustion testing; design and
construct 10-ton O2 per day CAR unit; integrate 10-ton O2
per day CAR unit with Alstom’s Multi-use Test Facility (MTF) in
Windsor, Connecticut; and test integrated CAR-MTF system in both
pulverized coal and circulating fluidized bed combustion
configurations.
