  • Patent number: 11977582
    Abstract: A global index with a repartitioning operator is provided. A method for executing a query includes receiving a query including a request to search a first table based on a first value in a first column. The method may include generating a second table by partitioning the second table based on the first column and including, in the second table, a partition identifier and a reference row identifier. The method may include pruning the second table such that a row corresponding to the first value remains in the second table. The method may include repartitioning the row to a stream based on the partition identifier. The method may include executing the query by at least searching the partition of the first table based on the stream and the row identifier of the row. Related systems and articles of manufacture are provided.

  • Patent number: 11969158
    Abstract: A catheter system includes a catheter, an introducer sheath, and a tubular plug. The catheter comprises an elongate body having an expandable medical device coupled with a distal end thereof. The introducer sheath comprises an elongate body defining a lumen therein. The introducer sheath is disposed over the catheter to form a gap therebetween. The tubular plug comprises an elongate body and extends through the lumen of the introducer sheath. The tubular plug is disposed between the catheter and the introducer sheath to occlude the gap. Further, the tubular plug is releasably fixed relative to the introducer sheath such that the tubular plug is removable from the lumen to allow the expandable medical device to pass therethrough.

  • Patent number: 10086326
    Abstract: 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.

  • Patent number: 10017434
    Abstract: 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.

  • Patent number: 9783467
    Abstract: 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.

  • Patent number: 9309171
    Abstract: 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.

  • Patent number: 9216931
    Abstract: 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.
