| 20090071190 | CLOSED CYCLE MIXED REFRIGERANT SYSTEMS - The present invention provides for a process for providing cooling and controlling the refrigeration in a cooling loop used in the production of liquefied natural gas. A cooling loop in contact with a heat exchanger contains a refrigerant composition and by controlling the amount of a component in the refrigerant composition, the necessary level of cooling provided to the heat exchanger can be maintained. | 03-19-2009 |
| 20120058045 | GAS FROM LANDFILL FOR USE IN HYDROGEN PRODUCTION - Methane collected from a landfill is used as a feedstock for the production of hydrogen in a steam methane reformer. This invention provides a green energy feed stock for the hydrogen production that benefits the environment. | 03-08-2012 |
| 20120067079 | NITROGEN REJECTION AND LIQUIFIER SYSTEM FOR LIQUIFIED NATURAL GAS PRODUCTION - A method for recovering liquefied natural gas from a gas mixture containing natural gas and impurities by subjecting the natural gas to a series of steps beginning with feeding a natural gas stream containing impurities to a nitrogen rejection unit; feeding the purified natural gas stream to a liquefier heat exchanger; expanding the liquefied natural gas and feeding the expanded liquefied natural gas to a flash vessel; flashing the liquid natural gas and separating the liquefied natural gas from the flash gas; and feeding the liquefied natural gas to storage and the flash gas to the nitrogen rejection unit. | 03-22-2012 |
| 20120085232 | METHODS FOR REMOVING CONTAMINANTS FROM NATURAL GAS - A method for removing contaminants from natural gas streams. The natural gas stream is fed to a dryer, then a membrane module and a multibed, multilayer vacuum swing adsorption process for removal of oxygen, nitrogen and carbon dioxide from the natural gas stream. Alternatively when carbon dioxide is in relatively low concentration in the natural gas stream, the membrane module step is not employed. | 04-12-2012 |
| 20120231127 | FOAMING BEVERAGES CONTAINING LIPIDS - A method for making a foaming beverage includes providing a beverage having at least one lipid-based ingredient therein and mixing nitrous oxide with said beverage. A beverage having a foam composition includes a liquid having at least one lipid-based ingredient therein and nitrous oxide mixed into the liquid. The nitrous oxide may be in gas phase. | 09-13-2012 |
| 20130205828 | INTEGRATION OF A LIQUEFIED NATURAL GAS LIQUEFIER WITH THE PRODUCTION OF LIQUEFIED NATURAL GAS - A method for integrating a liquefied natural gas liquefier system with production of liquefied natural gas from a methane-containing gas stream. The liquefied natural gas is produced by feeding a methane-containing gas stream through a heat exchanger to a distillation column and liquefying the natural gas while capturing the gaseous nitrogen. The liquefied natural gas is captured and the nitrogen gas is recovered, fed through the heat exchanger to recover cold and purified. | 08-15-2013 |
| 20140262285 | METHODS FOR FRACCING OIL AND GAS WELLS - A method for stimulating or fraccing an oil or a natural gas well by adding a liquefied hydrocarbon such as liquid petroleum gas and liquefied natural gas, a proppant and a diluent such as carbon dioxide, nitrogen or mixtures thereof to the well. The order of addition is typically liquefied hydrocarbon then diluent but this order can be reversed and in other circumstances the liquefied hydrocarbon and diluent can be mixed together and fed to the well as a mixture. | 09-18-2014 |
| 20140318177 | INTEGRATION OF A LIQUEFIED NATURAL GAS LIQUEFIER WITH THE PRODUCTION OF LIQUEFIED NATURAL GAS - A method for integrating a liquefied natural gas liquefier system with production of liquefied natural gas from a methane-containing gas stream. The liquefied natural gas is produced by feeding a methane-containing gas stream through a heat exchanger to a distillation column and liquefying the natural gas while capturing the gaseous nitrogen. The liquefied natural gas is captured and the nitrogen gas is recovered, fed through the heat exchanger to recover cold. | 10-30-2014 |
| 20140338393 | METHODS FOR BLENDING LIQUEFIED NATURAL GAS - A method for producing a blended mixture of liquefied natural gases to meet the particular requirements of an operator at a production facility, application site or a fueling station by blending together a lean liquefied natural gas and a rich liquefied natural gas. The operator can control through a device such as a heat exchange blending system the composition of the end product mixed liquefied natural gas for its intended end use. | 11-20-2014 |
