Patent number: 10086326Abstract: A gas separation module and assembly for housing ceramic tubular membranes. The module includes a plurality of tubes containing the ceramic tubular membranes. The tubes are arranged parallel to one another and are supported by tube sheet plates at each end. Gas-tight seals surround each membrane, preventing a feed gas and a residue gas within the inner lumen of the membrane from mixing with a permeate gas in the tube interior. The module also contains a gas distribution pipe for withdrawing the permeate gas out of, or introducing a sweep gas into, the module. This configuration allows for ceramic tubular membranes to be modularized for use in an assembly that carries out many types of gas separations.Type: GrantFiled: January 18, 2017Date of Patent: October 2, 2018Assignee: Membrane Technology and Research, Inc.Inventors: Paul Su, Moyeen Mohammed, Alicia Breen, Mamoon Rashid Khan, Nicholas P Wynn

Patent number: 10017434Abstract: Gas separation processes are provided for separating dehydrogenation reaction products from a raw gas stream to recover hydrocarbons, specifically olefins, such as propylene and iso-butene, as well as unreacted feedstock. The processes employ a sequence of partial condensation steps, interspersed with membrane separation steps to raise the hydrocarbon dewpoint of the uncondensed gas, thereby avoiding the use of low-temperature or cryogenic conditions.Type: GrantFiled: September 21, 2016Date of Patent: July 10, 2018Assignee: Membrane Technology and Research, Inc.Inventors: Nicholas P Wynn, Alvin Ng, Douglas Gottschlich, Paul Su, Meijuan Zhou, Sylvie Thomas-Droz

Patent number: 9783467Abstract: A process for treating an effluent gas stream arising from a manufacturing operation that produces an olefin or an olefin derivative to recover unreacted olefin. The process involves compressing the effluent gas stream, which comprises an olefin, a paraffin, and a third gas, to produce a first compressed stream, then directing the first compressed stream to a membrane separation pretreatment step. The permeate stream withdrawn from this step is enriched in olefin and is sent to a second compressor, which produces a second compressed stream that is then cooled and condensed. The condensation step produces a liquid condensate and an uncondensed gas stream. The uncondensed gas stream undergoes a second membrane separation step to produce another olefin-enriched permeate stream, which is recirculated within the process prior to the second compression step, and an olefin-depleted residue stream, which may be purged from the process.Type: GrantFiled: November 2, 2016Date of Patent: October 10, 2017Assignee: Membrane Technology and Research, Inc.Inventor: Paul Su

Patent number: 9309171Abstract: A process for treating an effluent gas stream arising from a manufacturing operation that produces an olefin or a non-polymeric olefin derivative. The process involves cooling and condensing the effluent gas stream, which comprises an olefin, a paraffin, and a third gas, to produce a liquid condensate and an uncondensed (residual) gas stream. Both streams are then passed through membrane separation steps. The membrane separation of the uncondensed gas stream results in an olefin-enriched stream and an olefin-depleted stream. The olefin-enriched stream is recirculated within the process prior to the condensation step. The membrane separation of the condensate also results in an olefin-enriched stream, which may be recycled for use within the manufacturing operation, and an olefin-depleted stream, which may be purged from the process.Type: GrantFiled: July 1, 2015Date of Patent: April 12, 2016Assignee: Membrane Technology and Research, Inc.Inventor: Paul Su

Patent number: 9216931Abstract: A process for recovering unreacted olefin in a polyolefin manufacturing process comprising the treatment of a purge bin vent gas. The process involves cooling and condensing the vent gas (purge stream), which contains at least an olefin, a paraffin, and hydrogen, to produce a liquid condensate and an uncondensed (residual) gas stream. Both streams are then passed through membrane separation steps. The membrane separation of the uncondensed gas stream results in a residue stream containing mostly nitrogen and/or paraffin and a permeate stream enriched in either C2+ hydrocarbons or olefin, depending on the type of separation. The permeate from this step is recirculated within the process prior to the condensation step. The membrane separation of the condensate results in a residue stream containing paraffin and a permeate stream enriched in olefin, which may be recycled to the polymerization reactor.Type: GrantFiled: May 27, 2015Date of Patent: December 22, 2015Assignee: Membrane Technology and Research, Inc.Inventor: Paul Su

Patent number: 8397098Abstract: A method for countervailing clock skew between a first clock signal and a second clock signal in a core logic circuit. The second clock signal is sampled based on the first clock signal in a sampling cycle to obtain a sampling result. When the sampling result indicates a non-compliant pattern, the phase of at least one of the first clock signal and the second clock signal is adjusted. Desirably, the core logic circuit keeps on working with the current first and second clock signals while continuing the sampling procedure of the second clock signal based on the first clock signal when the sampling result indicates a compliant pattern.Type: GrantFiled: October 24, 2007Date of Patent: March 12, 2013Assignee: Via Technologies, Inc.Inventor: Paul Su
