  • Patent number: 7901486
    Abstract: A process is disclosed for removing heavy metals from a hydrocarbon gas stream by contacting the hydrocarbon gas stream, which contains a heavy metal and less than 10 ppm oxidizing compounds, with a composition containing a molecular sieve and sulfur resulting in a treated stream containing less heavy metal than the hydrocarbon gas stream; wherein the molecular sieve contains alumina, silica, and iron, and optionally copper and zinc. Optionally, the hydrocarbon gas stream can also contain a sulfur compound.
    Type: Grant
    Filed: October 2, 2008
    Date of Patent: March 8, 2011
    Assignee: ConocoPhillips Company

  • Publication number: 20080250795
    Abstract: A system and method for production of gas from a cryogenic fluid using an improved air vaporizer in cyclic production/regeneration modes with a forced air draft and an intermittent heating of ambient air entering the air vaporizer during regeneration mode and/or optionally during the production mode. The system and method may be used in geographical areas where the ambient air temperature can be below freezing. Particularly, the system and method may employ a plurality of these improved air vaporizers for regasification of liquefied natural gas (LNG), particularly for continuous production of natural gas in a base-load LNG regasification plant.
