Low-Cost, Large-Membrane-Area Modules for Gas Separation

65043 Although U.S. refineries are short of hydrogen, many untapped sources exist, including off-gas and fuel gas streams that are generated on site. Membranes have been used to separate hydrogen from these gases, but many membrane modules are needed; therefore, the footprint and complexity of the membrane plants are excessive. This project will develop a new type of membrane module that will be 10 times larger than the current industry standard. These large modules will allow large refining gas streams to be treated with compact equipment. In Phase I, prototypes of the large modules will be prepared to determine the appropriate dimensions of the module components and to identify any necessary modifications to current module rolling protocols and equipment. Once these parameters are established, large modules will be prepared and tested. Commercial Applications and Other Benefits as described by awardee: Much larger membrane modules should allow membrane processes to be more widely used in hydrogen separation, as well as in other gas and liquid separations
