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 |
20130081426 | LOW TEMPERATURE HEAT EXCHANGER SYSTEM AND METHOD - A device for capturing carbon dioxide includes a supply source for supplying a compressed flue gas; a multi-stream heat exchanger for pre-cooling the compressed flue gas and a gas expansion device located downstream of the multi-stream heat exchanger. The multi-stream heat exchanger is configured to separate the compressed flue gas into a first compressed stream and a second compressed stream. The gas expansion device is configured to expand the compressed flue gas into a first sub-stream of carbon dioxide depleted gas and a second sub-stream of carbon dioxide. The device includes a first recirculation channel that recirculates a portion of the first sub-stream into the multi-stream heat exchanger and a second recirculation channel that recirculates at least a portion of the second sub-stream into the multi-stream heat exchanger, wherein the multi-stream heat exchanger is configured to pre-cool the compressed flue gas using the first sub-stream and the second sub-stream. | 04-04-2013 |
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 |

20140059930 | METHOD OF OPERATING A GASIFIER - A coal gasifier is retrofitted to achieve multiple advantages such as reduced oxygen consumption, reduced CO2 and NOx emissions, better H:C ratio, better carbon conversion etc. This is achieved by dividing the coal into at least two zones and modifying the gasifier and operating it as described. The coal is injected into a first zone, configured to devolatilize a substantial portion of the injected coal to produce coal char and volatiles. The operation is tuned to substantially consume the oxidant injected in the first zone. A low-calorific-value, high oxidant feedstock is injected in second zone of the gasifier. The devolatilization of the low-calorific-value, high oxidant content feedstock provides the oxygen containing compounds which gasify at least a portion of the coal char generated in the first zone. | 03-06-2014 |
20140148520 | CARBON TO LIQUIDS SYSTEM AND METHOD OF OPERATION - A method of operating a carbon to liquids system is provided. The method includes receiving a flow of syngas and reacting, in a reactor, the syngas and a catalyst in a Fischer-Tropsch reaction to produce a product including steam, wherein the reactor includes a polymeric material that is configured to permit the permeation of the steam therethrough. The method also includes recycling the permeated steam to a vessel positioned upstream from the reactor. | 05-29-2014 |
20140151051 | CO2 FRACTURING SYSTEM AND METHOD OF USE - An apparatus and method for delivering a thickened fluid mixture, including a CO | 06-05-2014 |
20150033792 | SYSTEM AND INTEGRATED PROCESS FOR LIQUID NATURAL GAS PRODUCTION - A system and method for producing liquid natural gas (LNG) from a natural gas stream is presented. The system includes a moisture removal device and compressor for removing moisture from and compressing the natural gas stream. The low moisture compressed natural gas stream is cooled in a heat exchanger to discharge a cooled compressed discharge stream. A multi-phase turbo expander provides for further cooling and expansion of the cooled compressed discharge stream, generating an expanded exhaust stream comprising a mixture of a vapor comprised substantially of CH | 02-05-2015 |
