| 20080276800 | METHOD TO CONDENSE AND RECOVER CARBON DIOXIDE (CO2) FROM CO2 CONTAINING GAS STREAMS - A method to condense and recover CO | 11-13-2008 |
| 20090028644 | METHOD TO INCREASE STORAGE CAPACITY OF NATURAL GAS STORAGE CAVERNS WITH A REFRIGERATION SYSTEM - A method to increase the storage capacity of a natural gas storage cavern includes effecting a heat exchange in a heat exchanger between a stream of coolant from a refrigeration or cooling plant and a natural gas stream to cool the natural gas stream prior to injecting the natural gas stream into the natural gas storage cavern. | 01-29-2009 |
| 20090282863 | METHOD TO PRODUCE NATURAL GAS LIQUIDS (NGL'S) AT GAS PRESSURE REDUCTION STATIONS - A method to recover NGL's at gas Pressure Reducing Stations. A first step involve providing at least one heat exchanger having a flow path for passage of high pressure natural gas with a counter current depressurized lean cold gas. A second step involves passing the high pressure natural gas stream in a counter current flow with the lean cold gas and cooling it before de-pressurization. A third step involves the expansion of the high pressure cooled gas in a gas expander. The expansion of the gas generates shaft work which is converted into electrical power by the power generator and the expanded low pressure and cold gas enters a separator where NGL's are recovered. This process results in the recovery NGL's, electricity and the displacement of a slipstream of natural that is presently used to pre-heat gas at Pressure Reduction Stations. | 11-19-2009 |
| 20100043439 | METHOD TO PRE-HEAT NATURAL GAS AT GAS PRESSURE REDUCTION STATIONS - A method to pre-heat gas at gas Pressure Reducing Stations. A first step involve providing at least one electrical line heater having a flow path for passage of natural gas through electrical heating elements. A second step involves passing the high pressure cold natural gas stream along electrical heating elements and heating it up before de-pressurization. A third step involves the expansion of the high pressure heated gas in a enclosed vessel that houses a gas expander and power generator. The expansion of the gas generates shaft work which is converted into electrical power by the power generator and the expanded low pressure gas cools the power generator. This process results in the recovery of energy to replace the slipstream of natural that is presently used to pre-heat gas at Pressure Reduction Stations. | 02-25-2010 |
| 20100189508 | METHOD OF INCREASING STORAGE CAPACITY OF NATURAL GAS STORAGE CAVERNS - A method of increasing the storage capacity of a natural gas storage cavern, involves the step of adding liquefied natural gas to gaseous natural gas in the natural gas storage caverns. The addition of liquefied natural gas serves to reduce the temperature and associated pressure of gaseous natural gas in the natural gas storage cavern, thereby increasing the capacity of the natural gas storage cavern. | 07-29-2010 |
| 20100215566 | METHOD TO CONDENSE AND RECOVER CARBON DIOXIDE FROM FUEL CELLS - A method to condense and recover carbon dioxide. A first step involve providing at more than one heat exchanger, with each heat exchanger having a first flow path for passage of a first fluid and a second flow path for passage of a second fluid. A second step involves passing a stream of very cold natural gas sequentially along the first flow path of each heat exchanger until it is heated for distribution and concurrently passing a gaseous stream rich in carbon dioxide sequentially along the second flow path of each heat exchanger, allowing a gaseous portion of the gaseous stream rich in carbon dioxide to pass to a next sequential heat exchanger and capturing in a collection vessel the condensed carbon dioxide. This processes results in a cryogenic heat exchange in which natural gas at Metering and Pressure Reduction | 08-26-2010 |
| 20100242499 | METHOD FOR RE-GASIFICATION OF LIQUID NATURAL GAS - A method for re-gasification of liquid natural gas involves positioning a storage vessel ( | 09-30-2010 |
| 20110089084 | EXTRACTION AND UPGRADING OF BITUMEN FROM OIL SANDS - A method to extract and process bitumen from oil sands involves processing in a pulse enhanced fluidised bed steam reactor, cracking the heavy hydrocarbon fractions, producing hydrogen in situ within the reactor and hydrogenating the cracked fractions using the natural bifunctional catalyst present in the oil sands. This method produces inert oil sands for soil rehabilitation and an upgraded oil stream. | 04-21-2011 |
