Recovery Act: Scale-Up of Hydrogen Transport Membranes for IGCC and FutureGen Plants
Performer: Eltron Research & Development Inc.
Project No: FC26-05NT42469
Eltron hydrogen transport membrane (HTM) technology uses composite metal alloy materials for separating hydrogen (H2) at practical rates from coal-derived synthesis gas (syngas), which is a mixture of H2, carbon monoxide (CO), carbon dioxide (CO2), and steam. Carbon dioxide on the feed side of the membrane remains at high pressure and in a concentrated form suitable for capture and re-use or storage. The Eltron HTM system is an enabling module for the production of high purity H2 and the capture of CO2 at high pressure, which is applicable to future integrated gasification combined cycle (IGCC) and central station H2 production plants. These novel membranes have an operating temperature of 280 to 440 degrees Celsius (°C), which is well-matched with emerging coal gas cleaning technologies and can significantly improve the overall efficiency and process economics for future gasification-based power, fuels, and chemical production plants. Eltron’s membranes can withstand high differential pressures of up to 1,000 pounds per square inch gauge (psig) without structural failure, allowing for successful integration into advanced high-pressure coal gasification plants.
