Low Cost High-H2 Syngas Projection for Power and Liquid Fuels
Project No: FE0011958
Performer: Gas Technology Institute
Proof-of-concept of a metal-polymeric membrane for hydrogen separation will be experimentally shown, along with identification of critical design data for integration of the membrane in a multi-contaminant removal process including a Pratt & Whitney Rocketdyne gasifier. Techno-economic analyses, assuming co-fed coal and natural gas for power, hydrogen and liquid fuels production will be used to evaluate advantages of this process.
Program Background and Project Benefits
Gasification is used to convert a solid feedstock, such as coal, petcoke, or biomass, into a gaseous form, referred to as synthesis gas or syngas, which is primarily hydrogen and carbon monoxide. With gasification-based technologies, pollutants can be captured and disposed of or converted to useful products. Gasification can generate clean power by adding steam to the syngas in a WGS reactor to convert the carbon monoxide to carbon dioxide (CO2) and to produce additional hydrogen. The hydrogen and CO2 are separated—the hydrogen is used to make power and the CO2 is sent to storage, converted to useful products or used for enhanced oil recovery. In addition to efficiently producing electric power, a wide range of transportation fuels and chemicals can be produced from the cleaned syngas, thereby providing the flexibility needed to capitalize on the changing economic market. As a result, gasification provides a flexible technology option for using domestically available resources while meeting future environmental emission standards. Polygeneration plants that produce multiple products are uniquely possible with gasification technologies. The Gasification Systems program is developing technologies in three key areas to reduce the cost and increase the efficiency of producing syngas: (1) Feed Systems, (2) Gasifier Optimization and Plant Supporting Systems, and (3) Syngas Processing Systems.
Syngas processing research and development underway emphasizes technologies that can be efficiently integrated into the plant, optimized with the temperature and pressure requirements of other systems, and meet product delivery specifications. A major cost element in gasification plants is converting raw syngas into a pure and specific gas used to create the plant’s target product suite. High-hydrogen, low-methane, ultraclean syngas is versatile and can be used for power production with CO2 capture, fuels or chemicals production, and for many polygeneration applications. The technologies being developed are focused on high-efficiency processes that operate at moderate to high temperatures and clean syngas of all contaminants to the extremely low levels needed for chemical production—often significantly lower than the U.S. Environmental Protection Agency (EPA) required levels for power plants.
Gas Technology Institute will conduct laboratory studies to establish the proof-of-concept of a metal-polymeric membrane, obtain additional critical design data for an integrated multi-contaminant removal process, and perform techno-economic analyses to integrate these technologies with a Pratt & Whitney Rocketdyne gasifier. The team will use coal co-fed with natural gas for power, hydrogen, and liquid fuels production cases and compare the systems with current hydrogen-from-coal technologies. Benefits of the technology include significant reductions in the cost of producing power with 90% carbon capture, and of producing diesel fuel, from coal.
The study Advanced Gasifier Pilot Plant Concept Definition prepared by Pratt Whitney Rocketdyne developed a concept for a gasification pilot plant incorporating advanced technologies. The current project builds upon that former work, in further assessing the potential of incorporation the metal-polymeric membrane technology in improving performance of gasification systems.
