摘要： A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is divided into first and second streams, and the second stream is cooled and expanded to a lower pressure and supplied to a contacting device. The first stream is cooled to condense substantially all of it, expanded to the lower pressure, and then used to cool a warmer distillation stream from a distillation column to at least partially condense the distillation stream. At least a portion of the partially condensed distillation stream is directed to the contacting device to intimately contact the expanded second stream, the resulting vapors and liquids are separated from the contacting device, and these liquids are supplied to the distillation column. The quantities and temperatures of the feeds to the contacting device and the distillation column are effective to maintain the overhead temperatures of the contacting device and the distillation column at temperatures whereby the major portion of the desired components is recovered.

摘要： A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbons from a liquefied natural gas (LNG) stream is disclosed. At least a portion of the LNG feed stream is directed in heat exchange relation with a compressed recycle portion of the fractionation tower overhead, with the warmed LNG stream thereafter supplied to the fractionation tower at a mid-column feed position. The recycle stream is cooled by the LNG stream sufficiently to substantially condense it, and the substantially condensed recycle stream is then supplied to the column at a top column feed position to serve as reflux for the tower. The pressure of the recycle stream and the quantities and temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of said desired components is recovered in the bottom liquid product from the column.

摘要： A process and an apparatus are disclosed for recovering ethane, ethylene, and heavier hydrocarbon components from a hydrocarbon gas stream. The stream is cooled, expanded to lower pressure, and supplied to a first fractionation tower at a mid-column feed position. A distillation liquid stream is withdrawn from the first fractionation tower below the feed position of the expanded stream, heated, and directed into a second fractionation tower that produces an overhead vapor stream and a bottom liquid stream. The overhead vapor stream is cooled to condense it, with a portion of the condensed stream directed to the second fractionation tower as its top feed and the remainder directed to the first fractionation tower at a lower column feed position. The bottom liquid stream from the second fractionation tower is cooled and directed to the first fractionation tower as its top feed.

摘要： A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is cooled to partially condense it, then separated to provide a first vapor stream and a first condensed stream. The first vapor stream is divided into first and second streams, then the first stream is combined with the first condensed stream. The combined stream is cooled and expanded to an intermediate pressure to partially condense it, then separated to provide a second vapor stream and a second condensed stream. The second vapor stream is cooled at the intermediate pressure to condense substantially all of it and is thereafter expanded to the fractionation tower pressure and supplied to the fractionation tower at a top feed position. The second condensed stream is subcooled at the intermediate pressure, expanded to the tower pressure, and is supplied to the column at a first mid-column feed position. The second stream is expanded to the tower pressure and is then supplied to the column at a second mid-column feed position. The quantities and temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the desired components is recovered. In an alternative embodiment, the combined stream is cooled at essentially inlet pressure to partially condense it, then separated at pressure to provide the second vapor stream and the second condensed stream.

摘要： A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. In recent years, the preferred method of separating a hydrocarbon gas stream generally includes supplying at least portions of the gas stream to a fractionation tower having at least one reboiler, and often one or more side reboilers, to supply heat to the column by withdrawing and heating some of the tower liquids to produce stripping vapors that separate the more volatile components from the desired components. The reboiler and side reboilers (if any) are typically integrated into the feed stream cooling scheme to provide at least a portion of the refrigeration needed to condense the desired components for subsequent fractionation in the distillation column. In the process disclosed, the tower reboiling scheme is modified to use one or more tower liquid distillation streams from a point higher in the column than is used in the conventional reboiling scheme, providing colder stream(s) for the reboiler(s) that allow more effective cooling of the feed streams and thereby improve the efficiency with which the desired components are recovered. In addition, the tower liquid streams withdrawn from a higher point in the column contain larger quantities of the more volatile components, which when vaporized provide better stripping of undesirable components like carbon dioxide without reducing the recovery of the desired components. The heated distillation stream is returned to a lower point on the fractionation tower that is separated from the withdrawal point by at least one theoretical stage.

摘要： A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. In recent years, the preferred method of separating a hydrocarbon gas stream generally includes supplying at least a portion of the gas stream to a work expansion device, then directing the work expanded stream to a distillation column at a mid-column feed point below an upper rectification section. The top column feed above the upper rectification section is typically a condensed and subcooled gaseous stream, frequently comprised of a gas stream that would otherwise feed the work expansion device. In the process disclosed, the work expanded stream is further cooled prior to feeding the distillation column at the mid-column feed point, so that a lesser volume of top column feed is required to maintain the column overhead temperature at a temperature whereby the major portion of the desired components is recovered.

摘要： A process and an apparatus are disclosed for a compact processing assembly to remove carbon dioxide from a hydrocarbon gas stream. The gas stream is cooled, expanded to intermediate pressure, and fed to the top of a mass transfer means. A distillation liquid stream from the mass transfer means is heated in a first heat and mass transfer means to strip out its volatile components and form a bottom liquid product. A distillation vapor stream from the mass transfer means is combined with any vapor in the expanded cooled gas stream, and the combined vapor stream is cooled in a second heat and mass transfer means to partially condense it, forming a condensed stream that is fed to the top of the mass transfer means. A portion of the bottom liquid product is subcooled, expanded to lower pressure, and used to cool the combined vapor stream.

摘要： A process and an apparatus are disclosed for a compact processing assembly to recover C2 (or C3) components and heavier hydrocarbon components from a hydrocarbon gas stream. The gas stream is cooled and divided into first and second streams. The first stream is further cooled, expanded to lower pressure, and supplied as a feed between two absorbing means. The second stream is expanded to lower pressure and supplied as a bottom feed to the lower absorbing means. A distillation liquid stream from the bottom of the lower absorbing means is heated in a heat and mass transfer means to strip out its volatile components. A distillation vapor stream from the top of the heat and mass transfer means is cooled by a distillation vapor stream from the top of the upper absorbing means, thereby forming a condensed stream that is supplied as a top feed to the upper absorbing means.
