Patent number: 9975079Abstract: A multi-stage process for recovering acid gas from natural gas having high acid gas contents utilizes two or more membrane absorption contactors arranged in series. The first membrane absorption contactor uses a physical solvent to remove a high volume of acid gas transferred across a membrane, and to reduce the acid gas content in the natural gas to a lower level that can be managed using chemical solvents. The second and, if needed, subsequent membrane absorption contactors can use a chemical solvent to remove acid gas transferred across the respective membranes and reduce the acid gas content in the natural gas to very low levels, if needed, depending on product specifications.Type: GrantFiled: April 25, 2017Date of Patent: May 22, 2018Assignee: GAS TECHNOLOGY INSTITUTEInventors: Shaojun Zhou, Howard S. Meyer

Patent number: 9901846Abstract: A process for removing carbon dioxide from a carbon dioxide-loaded solvent uses two stages of flash apparatus. Carbon dioxide is flashed from the solvent at a higher temperature and pressure in the first stage, and a lower temperature and pressure in the second stage, and is fed to a multi-stage compression train for high pressure liquefaction. Because some of the carbon dioxide fed to the compression train is already under pressure, less energy is required to further compress the carbon dioxide to a liquid state, compared to conventional processes.Type: GrantFiled: November 21, 2014Date of Patent: February 27, 2018Assignee: Gas Technology InstituteInventors: Shaojun Zhou, Howard S.

Publication number: 20160096732Abstract: A highly cost-efficient method and process for producing oxygen from a gaseous mixture such as air results in substantial energy savings compared to conventional methods. The gaseous mixture is fed to a membrane absorber in which oxygen from the gas is absorbed, through a first membrane by an oxygen-absorbing liquid that possesses suitable absorption and desorption properties. The resulting oxygen-rich carrier liquid is fed to a membrane desorber in which oxygen from the liquid is desorbed through a second membrane, suitably with the aid of a vacuum. The oxygen product suitably has greater than 95% purity, or greater than 99% purity.Type: ApplicationFiled: September 30, 2015Publication date: April 7, 2016Inventors: Shiguang LI, Shaojun Zhou, Howard S.

Patent number: 9249934Abstract: Adsorbent pellets coated with an outer nano-porous layer can be loaded with gas at loading pressures of 250 bar or greater, enabling a much higher loading than can be achieved at low pressures. The nano-porous layer provides nano-valves which can be sealed with an adsorbate such as ethanol or a hydrocarbon to close the nano-valves. The closed nano-valves maintain the high loading pressure inside the adsorbent pellets, and thus maintain the gas loading, during storage of the loaded nano-valved adsorbent pellets at much lower pressure. To release the gas, the nano-porous layer can be heated to a temperature sufficient to vaporize the adsorbate and open the nano-valves.Type: GrantFiled: April 25, 2014Date of Patent: February 2, 2016Assignees: Gas Technology Institute, University of Louisville Research Foundation, Inc., University of South CarolinaInventors: Shiguang Li, Shaojun Zhou, Howard S.

Patent number: 9243196Abstract: A method of processing synthesis gas improves the quality of the synthesis gas by using a water gas shift reaction to increase the molar ratio of hydrogen to carbon monoxide (H2:CO) in an efficient manner. A first steam of hot natural gas-based synthesis gas having a first higher molar ratio of H2:CO is combined with a second stream of quenched synthesis gas having a second lower molar ratio of H2:CO to provide a blend of synthesis gas having a third molar ratio of H2:CO that is between the first and second molar ratios. A non-catalytic water gas shift reaction increases the molar ratio of H2:CO to a fourth molar ratio that is higher than the third molar ratio, and can be about equal to or greater than the first molar ratio without supplying external heat.Type: GrantFiled: March 6, 2015Date of Patent: January 26, 2016Assignee: Gas Technology InstituteInventors: Bruce G. Bryan, Arunabha Basu, Howard S. Meyer

Patent number: 9227889Abstract: An exemplary embodiment can be a process for sweetening natural gas to liquefied natural gas specifications. The process can include providing a membrane contactor having a lumen side and a shell side. A feed natural gas is introduced to the lumen side of the membrane contactor. An absorption solvent is introduced to the shell side of the membrane contactor. CO2 and H2S are removed with the absorption solvent from the feed natural gas resulting in a sweetened natural gas containing less than 50 ppmv CO2 and less than 4 ppmv H2S. Corresponding or associated systems for such sweetening of natural gas are also provided.Type: GrantFiled: April 15, 2013Date of Patent: January 5, 2016Assignee: Gas Technology InstituteInventors: Shaojun Zhou, Howard S.
