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 and is thereafter expanded to the fractionation tower pressure and supplied to the fractionation tower at a lower mid-column feed position. A distillation stream is withdrawn from the column below the feed point of the stream and is then directed into heat exchange relation with the tower overhead vapor stream to cool the distillation stream and condense at least a part, of it, forming a condensed stream. At least a portion of the condensed stream is directed to the fractionation tower at an upper mid-column feed position. A recycle stream is withdrawn from the tower overhead after it has been warmed and compressed. The compressed recycle stream is cooled sufficiently to substantially condense it, and is then expanded to the pressure of the fractionation tower and supplied to the tower at a top column feed position. The quantities and temperatures of the feeds to the fractionation tower are effective to maintain the overhead temperature of the fractionation tower at a temperature whereby the major portion of the desired components is recovered.

摘要： Recovery of ethane, ethylene, propane, propylene, and heavier hydrocarbon components from a hydrocarbon gas stream. The stream is cooled and divided into first and second streams. The first stream is further cooled to condense it and is thereafter expanded to the fractionation tower pressure and supplied to the tower at mid-column. The second stream is expanded to the tower pressure and is supplied to the tower at mid-column. A distillation stream is withdrawn from the column below the feed point of the second stream and compressed, and is heat-exchanged with the tower overhead vapor stream to cool the distillation stream and condense it, forming a condensed stream which is the tower top feed. The system is effective to maintain the overhead temperature of the tower at an effective recovery temperature. The distillation stream can be withdrawn from the column above the feed point of the second stream.

摘要： A PROCESS FOR THE RECOVERY OF HEAVIER HYDROCARBONS FROM A LIQUEFIED NATURAL GAS (LNG) STREAM AND A HYDROCARBON GAS STREAM IS DISCLOSED. THE LNG FEED STREAM IS HEATED TO VAPORIZE AT LEAST PART OF IT, THEN EXPANDED AND SUPPLIED TO A FRACTIONATION COLUMN AT A FIRST MID-COLUMN FEED POSITION. THE GAS STREAM IS EXPANDED AND COOLED, THEN SUPPLIED TO THE COLUMN AT A SECOND MID-COLUMN FEED POSITION. A DISTILLATION VAPOR STREAM IS WITHDRAWN FROM THE FRACTIONATION COLUMN BELOW THE MID-COLUMN FEED POSITIONS AND DIRECTED IN HEAT EXCHANGE RELATION WITH THE LNG FEED STREAM, COOLING THE DISTILLATION VAPOR STREAM AS IT SUPPLIES AT LEAST PART OF THE HEATING OF THE LNG FEED STREAM. THE DISTILLATION VAPOR STREAM IS COOLED SUFFICIENTLY TO CONDENSE AT LEAST A PART OF IT, FORMING A FIRST CONDENSED STREAM. AT LEAST A PORTION OF THE FIRST CONDENSED STREAM IS DIRECTED TO THE FRACTIONATION COLUMN AT AN UPPER MID-COLUMN FEED POSITION. A PORTION OF THE COLUMN OVERHEAD STREAM IS ALSO DIRECTED IN HEAT EXCHANGE RELATION WITH THE LNG FEED STREAM, SO THAT IT ALSO SUPPLIES AT LEAST PART OF THE HEATING OF THE LNG FEED STREAM AS IT IS CONDENSED, FORMING A SECOND CONDENSED STREAM. THE SECOND CONDENSED STREAM IS DIVIDED INTO A “LEAN” LNG STREAM AND A REFLUX STREAM, WHEREUPON THE REFLUX STREAM IS SUPPLIED TO THE COLUMN AT A TOP 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 THE BOTTOM LIQUID PRODUCT FROM THE COLUMN.

摘要： Disclosed is a process for the separation of a gas stream containing methane, C2 components, C3 components, and heavier hydrocarbon components into a volatile residue gas fraction and a relatively less volatile fraction containing a major portion of said C2 components, C3 components, and heavier hydrocarbon components or said C3 components and heavier hydrocarbon components, in which process (a) said gas stream is cooled under pressure to provide a cooled stream; (b) said cooled stream is expanded to a lower pressure whereby it is further cooled; and (c) said further cooled stream is directed into a distillation column and fractionated at said lower pressure whereby the components of said relatively less volatile fraction are recovered; wherein following cooling, said cooled stream is divided into first and second streams; and (1) said first stream is cooled to condense substantially all of it and is thereafter expanded to said lower pressure whereby it is further cooled; (2) said expanded cooled first stream is thereafter supplied to said distillation column at an upper mid-column feed position; (3) said second stream is expanded to said lower pressure and is supplied to said distillation column at a mid-column feed position below said upper mid-column feed position; (4) an overhead vapor stream is withdrawn from an upper region of said distillation column and divided into at least a first portion and a second portion; (5) a distillation vapor stream is withdrawn from a region of said distillation column above said upper mid-column feed position and is combined with said first portion to form a combined vapor stream; (6) said combined vapor stream is compressed to higher pressure; (7) said compressed combined vapor stream is directed into heat exchange relation with said second portion, whereby said second portion is heated and said compressed combined vapor stream is cooled sufficiently to condense at least a part of it and thereby form a condensed stream, and thereafter discharging at least a portion of said heated second portion as said volatile residue gas fraction; (8) at least a portion of said condensed stream is expanded to said lower pressure and is thereafter supplied to said distillation column at a top feed position; and (9) the quantities and temperatures of said feed streams to said distillation column are effective to maintain the overhead temperature of said distillation column at a temperature whereby the major portions of the components in said relatively less volatile fraction are recovered.
