20090158660 | Process to Maximize Methane Content in Natural Gas Stream - The present invention relates to a hydrogenolysis process and catalyst for conversion of ethane to methane in a natural gas stream when such streams contain large quantities of ethane. Such natural gas streams include the product of the in situ treatment of oil shale to produce oil and gas. Hydrogenolysis catalysts have been identified that produce high yields of ethane at low light-off temperatures. | 06-25-2009 |
20110315010 | INTEGRATED MEMBRANE AND ADSORPTION SYSTEM FOR CARBON DIOXIDE REMOVAL FROM NATURAL GAS - The present invention relates to an integrated membrane/adsorbent process and system for removal of carbon dioxide from natural gas on a ship that houses natural gas purification equipment. Additional membrane units or adsorbent beds are used to reduce the amount of product gas that is lost in gas streams that are used to regenerate the adsorbent beds. These systems produce a product stream that meets the specifications of less than 50 parts per million carbon dioxide in natural gas for liquefaction. | 12-29-2011 |
20120000359 | NATURAL GAS PURIFICATION SYSTEM - The present invention relates to an integrated membrane/absorbent/adsorbent process and system for removal of mercury and sulfur compounds from natural gas on a ship that houses natural gas purification equipment. First mercury and most of the sulfur compounds are removed by an adsorbent bed and then the natural gas stream passes through a membrane unit to produce a partially purified natural gas residue stream to be dried and then liquefied and a carbon dioxide permeate stream that can be used as a fuel gas. | 01-05-2012 |
20130145931 | TETRAZOLE FUNCTIONALIZED POLYMER MEMBRANES - The present invention discloses a new type of high selectivity UV-cross-linked tetrazole group functionalized polymer nanosieve (TZPIM) membranes, their preparation, as well as their use for gas and liquid separations. The UV-cross-linked TZPIM membrane showed more than 50% improvement in CO | 06-13-2013 |
20130146538 | BLEND POLYMERIC MEMBRANES COMPRISING TETRAZOLE-FUNCTIONALIZED POLYMER OF INTRINSIC MICROPOROSITY AND POLYETHYLENE GLYCOL - The present invention is for high permeance and high selectivity blend polymeric membranes comprising poly(ethylene glycol) (PEG) and a highly permeable polymer selected from the group consisting of polymers of intrinsic microporosity (PIMs), tetrazole-functionalized polymers of intrinsic microporosity (TZPIMs), or mixtures thereof. The present invention also involves the use of such membranes for separations of liquids and gases. | 06-13-2013 |
20140020557 | METHODS AND APPARATUSES FOR GENERATING NITROGEN - Embodiments of methods and apparatuses for generating nitrogen are provided. In one example, a method comprises the steps of contacting at least a portion of a flue gas stream with a CO | 01-23-2014 |
