Abstract:
A CO 2 energy storage system includes a storage tank that stores a CO 2 slurry, including dry ice and liquid CO 2 , at CO 2 triple point temperature and pressure conditions. The storage system also includes a first pump coupled in flow communication with the storage tank. The first pump is configured to receive the CO 2 slurry from the storage tank and to increase a pressure of the CO 2 slurry to a pressure above the CO 2 triple point pressure. The energy storage system further includes a contactor coupled in flow communication with the first pump. The contactor is configured to receive the high pressure CO 2 slurry from the pump and to receive a first flow of gaseous CO 2 at a pressure above the CO 2 triple point pressure. The gaseous CO 2 is contacted and then condensed by the melting dry ice in the slurry to generate liquid CO 2
Abstract:
A method for separating carbon dioxide (CO 2 ) from a fluid stream comprising CO 2 and a liquid solvent is provided. The method includes receiving the fluid stream at a first flashing means to obtain a first CO 2 stream and a first CO 2 lean fluid stream enriched in the liquid solvent in comparison with the fluid stream. Further, the method also includes receiving the first CO 2 lean fluid stream at a second flashing means to obtain a second CO 2 stream and a second CO 2 lean fluid stream that is enriched in the liquid solvent in comparison with the first CO 2 lean fluid stream.
Abstract:
A cooling system and a related method is presented. The cooling system includes a reservoir configured to selectively supply a cooling fluid; a circulation loop fluidly coupled to the reservoir, and configured to circulate the cooling fluid to and from the reservoir; and a heat exchanger thermally coupled to the circulation loop and configured to exchange heat with the cooling fluid. The reservoir includes a refrigerant and an anti-freeze additive. The anti-freeze additive is characterized by a lower critical solution temperature (LCST) such that when an operating temperature of the reservoir is greater than the LCST, the reservoir is configured to supply a cooling fluid including the refrigerant to the circulation loop; and when the operating temperature of the reservoir is lower than the LCST, the reservoir is configured to supply a cooling fluid including the refrigerant and the anti-freeze additive to the circulation loop.
Abstract:
A method for processing a flowback composition stream from a well head (104) is provided. The flowback composition stream has a first flow rate (F1) and a first pressure (P1). Method also includes controlling the first flow rate to a second flow rate (F2) by regulating the flowback composition stream to a second pressure (P2). The method also includes separating the flowback composition stream into a first gas stream (166) and a condensed stream (165). The method includes discharging the condensed stream to a degasser (160) and degassing a carbon dioxide rich gas from the condensed stream. The method also includes mixing the carbon dioxide rich gas stream with the first gas stream to produce a second gas stream. The method includes controlling the third flow rate (F3) of the second gas stream by regulating the third pressure (P3) of the second gas stream to a fourth pressure (P4) that is different than the third pressure.

Abstract:
A fuel gas delivery system is provided. The fuel gas delivery system includes a feed line configured to provide a natural gas stream and a cryocooler fluidly coupled to the feed line. The cryocooler is configured to condense the natural gas to provide a liquefied natural gas (LNG) stream and to freeze impurities contained in the natural gas stream. The frozen impurities are separated from said LNG stream. A first heat exchanger is fluidly coupled to the cryocooler and the first heat exchanger is configured to vaporize at least a portion of the LNG stream to provide compressed natural gas. A delivery line is configured to supply the compressed natural gas to an end user and a removal line is configured to remove the impurities from the fuel gas delivery system.
