Publication number: 20190184332Abstract: A multi-stage membrane system is provided to separate helium from a gas stream such as a natural gas stream. There are at least two permeate streams from a first membrane module. One of the permeate streams is compressed and sent to a second membrane module while one of the permeate streams bypasses the compressor. There are control means provided to determine the flow for these two permeate streams based on factors including the compressor capacity, the concentration of the target component in the combined permeate streams and the capacity of the second membrane module.Type: ApplicationFiled: October 18, 2018Publication date: June 20, 2019Inventors: Tom Cnop, Mark E. Schott, David W. Greer, David Farr, Simon E. Albo

Patent number: 8388732Abstract: The present invention relates to an integrated membrane/adsorbent process and system for removal of carbon dioxide from natural gas on a ship that houses natural gas purification equipment. Additional membrane units or adsorbent beds are used to reduce the amount of product gas that is lost in gas streams that are used to regenerate the adsorbent beds. These systems produce a product stream that meets the specifications of less than 50 parts per million carbon dioxide in natural gas for liquefaction.Type: GrantFiled: May 11, 2011Date of Patent: March 5, 2013Assignee: UOP LLCInventors: Shain-Jer Doong, Lubo Zhou, Dennis J.

Patent number: 7943543Abstract: New ionic liquid-solid-polymer mixed matrix membranes were proposed for gas separations such as CO2 removal from natural gas or N2. For the new mixed matrix membranes, the solids such as carbon molecular sieves, microporous molecular sieves, MCM-41 type of mesoporous molecular sieves, or polymer of intrinsic microporosity (PIM) are coated (or impregnated) with ionic liquids such as 1-butyl-3-methyl imidazolium bis[trifluoromethylsulfonyl]amide. The ionic liquids coated or impregnated solids are then dispersed in the continuous polymer matrix to form mixed matrix membranes. These hybrid mixed matrix membranes will combine the properties of the continuous polymer phase, the ionic liquids, and the dispersed ionic liquids coated or impregnated solids phase, which will possibly open up new opportunities for gas separation processes such as CO2 separation from natural gas or flue gas.Type: GrantFiled: September 29, 2006Date of Patent: May 17, 2011Assignee: UOP LLCInventors: Chunqing Liu, Santi Kulprathipanja, Mark E.

Patent number: 7799117Abstract: A thermal sink is used to recover heat from a product gas leaving an adsorption vessel in a thermal swing adsorption process. Heat that is recovered from the product gas is used to heat a regeneration gas during the subsequent regeneration of the adsorbent material within the adsorption vessel. The step in which the regenerated bed of adsorbent material is cooled prior to returning to adsorption mode is eliminated.Type: GrantFiled: September 27, 2006Date of Patent: September 21, 2010Assignee: UOP LLCInventors: Lin Li, Mark E.

Patent number: 7637983Abstract: Metal-organic framework (MOF)-polymer mixed matrix membranes (MOF-MMMs) have been prepared by dispersing high surface area MOFs (e.g. IRMOF-1) into a polymer matrix (e.g. Matrimid 5218). The MOFs allow the polymer to infiltrate the pores of the MOFs, which improves the interfacial and mechanical properties of the polymer and in turn affects permeability. Pure gas permeation tests show the incorporation of 20 wt-% of IRMOF-1 in Matrimid 5218 polyimide matrix results in 280% improvement in CO2 permeability without a loss of CO2/CH4 selectivity compared to those of the pure Matrimid 5218 membrane. This type of MOF-MMMs has significantly improved gas separation performance with dramatically high CO2 permeability (>35 barrer) and higher than 29 CO2/CH4 selectivity at 50° C. under 100 psig pressure, which are attractive candidates for practical gas separation applications such as CO2 removal from natural gas.Type: GrantFiled: June 30, 2006Date of Patent: December 29, 2009Assignee: UOP LLCInventors: Chunqing Liu, Beth McCulloch, Stephen T.
