  • Publication number: 20140231313
    Abstract: A cascading processor is described which includes a processor body having an upper inlet and a lower outlet, such that materials pass by force of gravity from inlet to the outlet. The processor body has a plurality of processing levels Which are sequentially vertically spaced progressively downwardly from the inlet to the outlet, such that materials cascade by force of gravity from one processing level to another processing level as the materials pass through the processor body front the inlet to the outlet. This cascading processor was developed for recovery of bitumen front oil sands, but can be used to process oil shales or to process biomasses.

  • Patent number: 8640494
    Abstract: 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.

  • Patent number: 8585891
    Abstract: A method to extract and process bitumen from oil sands involves processing in a pulse enhanced fluidized 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.

  • Patent number: 8555671
    Abstract: A method of conditioning natural gas in preparation for storage, involves taking an existing stream of continuously flowing natural gas flowing through a gas line (12) on its way to end users and diverting a portion of the stream of continuously flowing natural gas to a storage facility through a storage diversion line (22). The pressure of the natural gas is lowered, as is the temperature by the Joule-Thompson effect. The natural gas is passed in a single pass through a series of heat exchangers (18, 28,30, 32) prior to resuming flow through the gas line (12) at the lowered pressure. The diverted natural gas is liquefied in preparation for storage by effecting a heat exchange with the natural gas.

  • Patent number: 8429932
    Abstract: A method for selective extraction of natural gas liquids from “rich” natural gas. The method involves interacting a rich natural gas stream with Liquid Natural Gas (LNG) by mixing Liquid Natural Gas into the rich natural gas stream to lower the temperature of the rich natural gas stream to a selected hydrocarbon dew point, whereby a selected hydrocarbon liquid carried in the rich natural gas stream is condensed.

  • Patent number: 8375717
    Abstract: 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.

  • Publication number: 20130001064
    Abstract: A method of upgrading heavy oil in which the heavy oil is preheated to above a boiling point of water to remove water as steam and lighter fractions as vapours. The heavy oil passes downwardly through a series of sequential horizontal heat gradients in a temperature gradient reactor. A temperature of each sequential heat gradient progressively increases so that lighter fractions of the heavy oil vaporize with minimal cracking and heavier heavy oil fractions continue to fall by force of gravity downwards. As they pass through further sequential heat gradients of progressively increasing temperature, they tend to crack into lighter fractions in the presence of nascent hydrogen. Coke, formed from heavier heavy oil fractions generated and deposited on a fluidized catalytic bed a bottom of the temperature gradient reactor, is fluidized with superheated steam.

  • Patent number: 8128317
    Abstract: 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 cavern. 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.

  • Patent number: 8088528
    Abstract: 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.

  • Publication number: 20100242499
    Abstract: A method for re-gasification of liquid natural gas involves positioning a storage vessel (22) for liquid natural gas at a facility (12) that has at least one refrigeration unit (48) with circulating fluid heat transfer medium. A second step involves providing at least one heat exchanger (24). A heat exchange takes place during circulation through the heat exchanger between the liquid natural gas and the circulating fluid heat transfer medium which raises the temperature of the liquid natural gas changing it from a liquid phase to a gaseous phase in preparation for consumption and which lowers the temperature of the circulating fluid heat transfer medium in preparation for use in the at least one refrigeration unit (48).
