摘要： Un proceso y un aparato para un conjunto de procesamiento compacto para mejorar la recuperación de componentes C₂ (o C₃) y componentes hidrocarburos más pesados de una corriente gaseosa de hidrocarburos. El método preferido para separar un corriente gaseosa de hidrocarburos incluye en general producir por lo menos una primera corriente condensada sustancialmente y una segunda corriente enfriada, expandir ambas corrientes a menor presión, y suministrar las corrientes a una torre de fraccionamiento. En el proceso y el aparato que se divulgan, el vapor de cabeza de la torre se dirige a un medio de absorción y un medio de transferencia térmica y de masa en el interior de un conjunto de procesamiento. El vapor que sale del conjunto de procesamiento se comprime a una presión mayor y se enfría, luego se condensa sustancialmente una parte en un medio de intercambio térmico en el interior del conjunto de procesamiento, se expande a una presión menor, y se suministra al medio de transferencia térmica y de masa para proveer enfriamiento. El líquido condensado proveniente del medio de absorción se alimenta a la torre.

摘要： Un proceso y un aparato para recuperar etano, etileno, y componentes hidrocarburos más pesados de una corriente de gas de hidrocarburos. La corriente se enfría, se expande a una menor presión, y se suministra a una primera torre de fraccionamiento por una posición de alimentación en la parte media de la columna. De la primera torre de fraccionamiento se extrae una corriente del líquido de destilación por debajo de la posición de alimentación de la corriente expandida, se calienta, y se la dirige hacia el interior de una segunda torre de fraccionamiento que produce una corriente de vapor de cabeza y una corriente de líquido del fondo. El vapor de la corriente de cabeza se enfría para condensarlo, y una parte de la corriente de condensado se dirige hacia la segunda torre de fraccionamiento alimentándola por su posición de alimentación superior y donde el resto se dirige hacia la primera torre de fraccionamiento por una posición de alimentación en la parte inferior de la columna. La corriente de líquido del fondo proveniente de la segunda torre de fraccionamiento se enfría y se dirige hacia la primera torre de fraccionamiento como su alimentación superior.

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 (50) HAVING AT LEAST ONE REBOILER (57), AND OFTEN ONE OR MORE SIDE REBOILERS, TO SUPPLY HEAT TO THE COLUMN (19) 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 (57) 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 (17). 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 (45,40, 61) 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 (19,17,50) THAT IS SEPARATED FROM THE WITHDRAWAL POINT BY AT LEAST ONE THEORETICAL STAGE.(FIGURE 3)

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 and an apparatus are disclosed for a compact processing assembly to improve the recovery of C2 (or C3) and heavier hydrocarbon components from a hydrocarbon gas stream. The preferred method of separating a hydrocarbon gas stream generally includes producing at least a substantially condensed first stream and a cooled second stream, expanding both streams to lower pressure, and supplying the streams to a fractionation tower. In the process and apparatus disclosed, the tower overhead vapor is directed to an absorbing means and a heat and mass transfer means inside a processing assembly. The outlet vapor from the processing assembly is compressed to higher pressure and cooled, then a portion is substantially condensed in a heat exchange means inside the processing assembly, expanded to lower pressure, and supplied to the heat and mass transfer means to provide cooling. Condensed liquid from the absorbing means is fed to the tower.

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. (FIG. 1)

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.
