Patent number: 8518150Abstract: Methods for the purification of steam, systems for purifying steam, methods for measuring and/or controlling steam flow rates, and uses for purified steam are provide. Also provided are substantially gas-impermeable membranes, such as perfluorinated ionomers (e.g., perfluoroethylene-sulfonic-acid/tetrafluoroethylene membranes), having a high ratio of water vapor permeation relative to gas permeation through the membrane. Also provided are methods of operation of such membranes at relatively high operating temperatures for the purification of steam and for operation of such membranes at relatively low temperature and sub-atmospheric pressures for the purification of steam. In a preferred embodiment, the system 400 for purifying steam comprises heater 404 for creating a source of a steam feed, and a purification device 416 for housing a substantially gas-impermeable membrane 424. In the operation of system 400, water, such as deionized water, is added to vessel 402 to provide a source of the steam feed.Type: GrantFiled: August 28, 2012Date of Patent: August 27, 2013Assignee: RasircInventors: Jeffrey J.
