Abstract: A method for controlling gas separation of a gas mixture comprising a first component and a second component, the method comprising contacting a feed containing the gas mixture with an adsorbent in a bed in a column in a dual reflux swing adsorption process such that a first component of a gas mixture attains or exceeds a desired purity and a second component of the gas mixture attains or exceeds a desired purity, wherein the mathematical product of the cycle feed time and the sum of the molar feed flow rate and the molar reflux flow rate directed to the column does not exceed the maximum number of moles that can be treated per bed per cycle and wherein the ratio of the first product flow rate to the feed flow rate is less than or equal to the first component's fraction of the feed, and the ratio of the second product flow rate to the feed flow rate is less than or equal to the second component's fraction of the feed.

Abstract: Disclosed are processes and systems for preventing overpressurization of piping transporting fluid produced from a pressure source to a receiving facility in which the fluid passes through a high integrity pressure protection system (HIPPS). A relief device is provided in the piping in fluid communication with the HIPPS. In the event that fluid passing through the HIPPS during the valve closure time period has a property exceeding an activation property, the relief device is activated thereby allowing the fluid passing through the HIPPS during the valve closure time period to flow to a fluid containment volume. The fluid containment volume has sufficient volume such that upon the start of the closure of the valve in response to the pressure surge, a portion of the fluid passing through the HIPPS during the valve closure time period is absorbed by the fluid containment volume thereby lessening pressure increase in the piping.

Abstract: A process and system for separating CO2 from a flue gas stream is disclosed. The process involves (a) contacting a flue gas stream containing water vapor and CO2 with an ionic absorbent under absorption conditions to absorb at least a portion of the CO2 from the flue gas stream and form a CO2-absorbent complex; wherein the ionic absorbent comprises a cation and an anion comprising an amine moiety; and (b) recovering a gaseous product having a reduced CO2 content.

Abstract: Embodiments for deliquification of produced fluid being produced from a well are provided. In one embodiment, a system comprises a production tubing, a casing, or both that receive the produced fluid from a subterranean reservoir and provide a pathway for transmission of the produced fluid to a surface location. The system also comprises a nozzle disposed within the production tubing, the casing, or both. The nozzle includes a passageway extending between an intake and a diffuser such that the produced fluid received by the intake flows through the nozzle via the passageway. The passageway includes a region of decreased cross-sectional area at a throat that reduces the pressure of the produced fluid passing through the nozzle and the produced fluid is deliquefied as it flows through the passageway. The system also comprises a sealer, a stopper, or both coupled to the nozzle to form a nozzle assembly.

Abstract: Various embodiments of identifying a clathrate deposit in a subsurface from seismic data are provided. In one embodiment, a method includes using a computing system in generating a land surface or sea floor digital image from post-stack seismic data; determining a clathrate stability zone from the land surface or sea floor digital image; generating a laterally extensive subsurface digital image from the seismic data that is within or below the clathrate stability zone; filtering the laterally extensive subsurface digital image to generate a pull-up digital image; generating a coarse-grained sediment digital image from the seismic data within the clathrate stability zone; spatially superimposing the coarse-grained sediment digital image and the pull-up digital image to generate a combined digital image; and determining an overlap region from the combined digital image. The overlap region is indicative of a clathrate deposit. Also provided are embodiments of producing hydrocarbons.
