Patent number: 10259711Abstract: Systems and methods are provided for separating oxygen from air using a sorption/desorption cycle that includes a reduced or minimized difference between the maximum and minimum pressures involved in the sorption/desorption cycle. The reduced or minimized difference in pressures can be achieved in part by using valves that can allow for commercial scale flow rates while avoiding large pressure drops for flows passing through the valves. A rotary wheel adsorbent is an example of a system that can allow for a sorption/desorption cycle with reduced and/or minimized pressure drops across valves associated with the process. Stationary adsorbent beds can also be used in combination with commercially available valves that have reduced and/or minimized pressure drops.Type: GrantFiled: March 22, 2017Date of Patent: April 16, 2019Assignee: ExxonMobil Research and Engineering CompanyInventors: Ramesh Gupta, Robert A. Johnson, Thomas N. Anderson, Harry W. Deckman, Peter I. Ravikovitch

Patent number: 9034079Abstract: A pressure swing adsorption process for removal of CO2 from natural gas streams through a combination of a selective adsorbent material containing an effective amount of a non-adsorbent filler, adsorbent contactor design, and adsorption cycle design. The removal of contaminants from gas streams, preferably natural gas streams, using rapid-cycle swing adsorption processes, such as rapid-cycle pressure swing adsorption (RC-PSA). Separations at high pressure with high product recovery and/or high product purity are provided through a combination of judicious choices of adsorbent material, gas-solid contactor, system configuration, and cycle designs. For example, cycle designs that include steps of purge and staged blow-down as well as the inclusion of a mesopore filler in the adsorbent material significantly improves product (e.g., methane) recovery. An RC-PSA product with less than 10 ppm H2S can be produced from a natural gas feed stream that contains less than 1 mole percent H2S.Type: GrantFiled: February 27, 2012Date of Patent: May 19, 2015Assignee: ExxonMobil Upstream Research CompanyInventors: Harry W. Deckman, Robert A. Johnson, Bruce T. Kelley, Peter I. Ravikovitch, Thomas N. Anderson

Patent number: 8784534Abstract: A pressure-temperature swing adsorption process for the removal of a target species, such as an acid gas, from a gas mixture, such as a natural gas stream. Herein, a novel multi-step temperature swing/pressure swing adsorption is utilized to operate while maintaining very high purity levels of contaminant removal from a product stream. The present process is particularly effective and beneficial in removing contaminants such as CO2 and/or H2S from a natural gas at high adsorption pressures (e.g., at least 500 psig) to create product streams of very high purity (i.e., very low contaminant levels).Type: GrantFiled: February 27, 2012Date of Patent: July 22, 2014Assignee: Exxonmobil Research and Engineering CompanyInventors: Preeti Kamakoti, Daniel P.

Patent number: 8784535Abstract: The present invention relates to a pressure-temperature swing adsorption process wherein gaseous components that have been adsorbed can be recovered from the adsorbent bed at elevated pressures. In particular, the present invention relates to a pressure-temperature swing adsorption process for the separation of C2+ hydrocarbons (hydrocarbons with at least 2 carbon atoms) from natural gas streams to obtain a high purity methane product stream. In more preferred embodiments of the present processes, the processes may be used to obtain multiple, high purity hydrocarbon product streams from natural gas stream feeds resulting in a chromatographic-like fractionation with recovery of high purity individual gaseous component streams.Type: GrantFiled: February 27, 2012Date of Patent: July 22, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Peter I.

Herein, a novel multi-step temperature swing/pressure swing adsorption is utilized to operate while maintaining very high purity levels of contaminant removal from a product stream. The present process is particularly effective and beneficial in removing contaminants such as CO2 and/or H2S from a natural gas at relatively high adsorption pressures (e.g., at least 500 psig) to create product streams of very high purity (i.e., very low contaminant levels).Type: GrantFiled: February 27, 2012Date of Patent: July 22, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Daniel P.

Patent number: 6982426Abstract: A nitric oxide sensor and method is disclosed. The sensor is based on sum-frequency mixing of a tunable, 395-nm external cavity diode laser with a 532-nm diode-pumped intracavity-frequency-doubled Nd:YAG laser in a beta-barium-borate crystal. The output from the BBO crystal is ultraviolet radiation at 227 nm and is split using a 50—50 beam splitter. Half of the radiation is directed into a reference photomultiplier tube, and the other half of the UV radiation is directed through the medium of interest and then directed into a signal photomultiplier tube. The output from the photomultiplier tubes is compared and the difference utilized to indicate the level of nitric oxide by absorption-based spectrosocpic techniques.Type: GrantFiled: August 6, 2004Date of Patent: January 3, 2006Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Robert P.
