Project Description

TDA Research Inc. (TDA) will develop an integrated water-gas shift (WGS) pre-combustion CO2 capture technology to eliminate CO2 emissions from integrated gasification combined cycle (IGCC) power plants and coal-to-liquid plants. The project team includes the Gas Technology Institute (GTI); the University of California, Irvine (UCI); Indigo Power Systems LLC (Indigo); the National Carbon Capture Center (NCCC); and CB&I Lummus Technology (CB&I). The team will design a gasification reactor using computational fluid dynamics and kinetic modeling to achieve optimum CO2 removal and hydrogen recovery. TDA will be the lead and perform the system design and sorbent production. TDA will work with GTI in the design and fabrication of a slipstream test unit. UCI and Indigo will conduct the process modeling and design and carry out the system and economic analyses. NCCC and CB&I will support the field tests at the NCCC in Wilsonville, AL, and at the Wabash River IGCC plant in Terre Haute, IN.

Project Benefits

TDA will develop a new carbon capture technology that can be used in IGCC and coal-to-liquid plants that run on a wide range of coals (bituminous to low-rank) and petcoke. TDA’s integrated WGS pre-combustion CO2 control system achieves a high CO2 capacity and removal efficiency (greater than 90 percent) at temperatures well above the syngas dew point for all commercial gasifiers. This high-temperature CO2 removal capability eliminates the need to condense the steam in the gas and maximizes the mass flow through the gas turbine, thereby increasing the efficiency of the power cycle. This technology will provide U.S. developers with an effective carbon capture system that is much more efficient than conventional low temperature scrubbers.
