  • Patent number: 8926731
    Abstract: A system and method of controlling a flow of steam in a steam generator having a heater for heating fluid in a vessel is disclosed. The method includes: delivering the steam from the steam generator to a first side of a filtering membrane; receiving purified steam from a second side of the filtering membrane, the purified steam having a steam flow rate; determining at least one coefficient of a substantially linear mathematical relationship between the steam flow rate of the purified steam and duty cycle; and configuring the steam generator to control: the duty cycle of the heater based on the determined at least one coefficient and a target steam flow rate; and/or the target steam flow rate based on the at least one coefficient and a target duty cycle of the heater.

  • Patent number: 8518150
    Abstract: 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.

  • Publication number: 20110233069
    Abstract: An apparatus, a system and a method for electrochemical generation of hydrogen are disclosed. The apparatus may include a cathode, a polymer electrolyte membrane surrounding the cathode and a housing surrounding the polymer electrolyte membrane. The housing may include an anode electrically connected to the cathode. The system for electrochemical generation of hydrogen may include a water purifier in fluid communication with a hydrogen generating unit, an electrolyte source in fluid communication with the hydrogen generation unit and a power source electrically connected to the hydrogen generating unit. The method may include passing water and electrolyte into the hydrogen generation unit and applying a voltage between the anode and the cathode to generate hydrogen gas.
