20120251898 | RECIRCULATION COMPLEX FOR INCREASING YIELD FROM FUEL CELL WITH CO2 CAPTURE - A system and method are provided for boosting overall performance of a fuel cell while simultaneously separating a nearly pure stream of CO | 10-04-2012 |
20130084794 | SYSTEMS AND METHODS FOR PROVIDING UTILITIES AND CARBON DIOXIDE - A system for producing at least one of solid or liquid carbon dioxide includes a combustor configured to produce an exhaust gas containing carbon dioxide, a compressor configured to compress the exhaust gas and a heat exchanger configured to cool the exhaust gas. An expansion chamber is configured to allow the compressed exhaust gas to expand and form the solid or liquid carbon dioxide and to separate the solid or liquid carbon dioxide from a substantially CO2 depleted gas. A supply passage supplies the CO2 depleted gas to said heat exchanger and a storage chamber stores the solid carbon dioxide. | 04-04-2013 |
20140174083 | CRYOGENIC FUEL SYSTEM WITH AUXILIARY POWER PROVIDED BY BOIL-OFF GAS - A system in one embodiment includes a detection unit, a boil-off auxiliary power unit, and a controller. The detection unit is configured to detect a characteristic of a boil-off gas stream from a cryotank configured to hold a cryogenic fluid. The boil-off auxiliary power unit is configured to receive the boil-off gas stream and use the boil-off gas stream to provide auxiliary power to a vehicle system. The controller is configured to acquire information from the detection unit corresponding to the characteristic; determine, using the information acquired from the detection unit, an available boil-off auxiliary energy that is available from the boil-off auxiliary power unit; determine a mode of operation of the vehicle system; determine a required auxiliary energy for the vehicle system; and to operate the auxiliary power unit based on the available boil-off auxiliary energy, the mode of operation, and the required auxiliary energy. | 06-26-2014 |
20140174103 | SYSTEMS AND METHODS FOR OXIDATION OF BOIL-OFF GAS - A system in one embodiment includes a mixing module, an oxidation module, and a heat exchanger. The mixing module is configured to receive and mix a boil-off gas stream from a cryotank. The oxidation module is configured to receive the mixed stream, and to oxidize the boil-off gas in the mixed stream to produce an exhaust stream. The heat exchanger is configured to exchange heat between streams passing through a first passage configured to receive at least a portion of the exhaust stream, and a second passage configured to receive a fluid including the boil-off gas. The heat exchanger is configured to heat the fluid including the boil-off gas and cool the at least a portion of the exhaust stream. The fluid including the boil-off gas is heated by the heat exchanger upstream of the oxidation module. | 06-26-2014 |
20140174105 | SYSTEMS AND METHODS FOR RE-CONDENSATION OF BOIL-OFF GAS - A system in one embodiment includes a heat exchanger, a detection unit, and a controller. The heat exchanger includes a first passage and a second passage configured for exchange of heat therebetween. The first passage is configured to receive a boil-off gas stream of a first cryogenic fluid. The second passage is configured to receive a liquid stream of a second cryogenic fluid. The detection unit is configured to detect a characteristic of the boil-off gas stream. The controller is configured to, responsive to information acquired from the detection unit corresponding to the characteristic, control the flow of the second cryogenic fluid to provide sufficient exchange of heat from the boil-off gas stream via the heat exchanger to condense at least a portion of the boil-off gas stream. A liquid stream of the first cryogenic fluid is output from the first passage and returned to a first tank. | 06-26-2014 |
20140318792 | SYSTEM AND METHOD FOR ENHANCED RECOVERY OF OIL FROM AN OIL FIELD - An oil recovery system and method is disclosed. The system includes a solar power tower for receiving a first portion of water from a water treatment device. The solar power tower heats the first portion of water directly using solar radiation and generates a first steam. Further, the system includes a boiler for receiving a second portion of water from the water treatment device. The boiler heats the second portion of water and generates a second steam. Further, the system includes a flow control device coupled to the solar power tower and the boiler to receive at least one of the first steam and the second steam. The flow control device injects at least one of the first steam and the second steam to an oil field. | 10-30-2014 |

20130239608 | SYSTEM AND METHOD FOR SEPARATING COMPONENTS IN A GAS STREAM - An incoming compressed gas, such as natural gas, is pre-cooled and the gas separated from any included liquid. The pre-cooled and separated gas is expanded using an expander to rapidly reduce pressure and corresponding temperature, as well as remove any components solidified by the temperature drop. An output stream from the expander, combined with other streams, is again gas/liquid separated. The output separated gas stream is sent through another expansion and gas/liquid separation, separating one or more other components, such that a final output gas is achieved. In the case of natural gas, the final output is, for example, methane, which may be fed back to cool the incoming gas prior to end use of the methane. | 09-19-2013 |
20140174106 | CRYOGENIC TANK ASSEMBLY - A cryogenic tank assembly includes a cryogenic tank having an internal volume that is configured to contain liquefied natural gas (LNG). The cryogenic tank includes an inlet and an outlet that are each fluidly connected to the internal volume. The assembly includes a recirculation conduit coupled in fluid communication between the inlet and the outlet. The recirculation conduit extends along a path between the inlet and outlet external to the internal volume of the cryogenic tank such that the path is configured to be exposed to an ambient environment of the cryogenic tank. The recirculation conduit is configured to: receive a flow of LNG from the internal volume through the outlet; transfer heat from the ambient environment to the LNG flow to change the LNG flow to a flow of natural gas; and inject the natural gas flow into the internal volume of the cryogenic tank through the inlet. | 06-26-2014 |
