Definitions
- the invention relates to a method for separating a C 2+ -rich fraction from liquefied natural gas (LNG).
- LNG liquefied natural gas
- Generic methods are BSOW. provided that the calorific value of liquefied natural gas does not meet the desired specifications of the pipeline network into which the natural gas is to be fed. In such a case, either a calorific-lowering component, such as nitrogen, is added to the liquefied natural gas or components causing an increase in calorific value are removed from the liquefied natural gas.
- a calorific-lowering component such as nitrogen
- Object of the present invention is to provide a generic method for separating a C 2+ -rich fraction of liquefied natural gas (LNG), the an increase in the yield of C 2+ -rich fraction while reducing the investment and operating costs of the process, in particular the absence of compression of the methane-rich gas fraction allows.
- LNG liquefied natural gas
- the first Ci-rich gas fraction obtained in the separation of the partially vaporized natural gas is now reliquefied and at least partially led to the rectification separation as reflux.
- the cold required for the re-liquefaction of the first gas fraction can in this case only be provided by the liquid natural gas stream, which is subjected to heating up to at most the boiling point. Since the rectification separation discontinued as reflux Ci-rich gas fraction having a relatively low ethane content, a back washing of ethane and heavier components from the overhead product of the rectification separations and thus the desired increase in C is effected 2+ yield through it.
- the process according to the invention therefore makes it possible to realize ethane yields of more than 90% in an economically sensible procedure.
- This value is in the range of ethane yield, as can be achieved with the complex process according to L) SA 5,114,451, but significantly above the value in a process according to US-A 3,420,068.
- the method according to the invention as well as further embodiments thereof, which constitute subjects of the dependent claims, will be explained in more detail below with reference to the exemplary embodiment illustrated in FIGS. 1 and 2.
- the partially vaporized natural gas stream is fed via line 2 to a separator D1.
- a separation takes place of the partially vaporized natural gas stream into a first C r-rich gas fraction which is taken off at the top of the separator D1 via line 4 and a first liquid fraction rich C 2+.
- the latter is supplied via line 3, in which a pump P3 is provided to the separation column T and thus the rectification separation.
- Rectification are provided in which the separation of the partially vaporized natural gas 2 is realized.
- the feed of the partially evaporated natural gas stream 2 would take place in the bottom of the rectification column.
- the required column reflux can be realized either by means of a withdrawn from the still to be described line 6 stream or from the still to be described line 8 after the heat exchanger E2 and before the valve c withdrawn stream.
- a rectification separation of the above-C takes place 2+ -rich liquid fraction 3 in a second C r-rich gas fraction which is withdrawn at the head of the separating column T via line 8, and a second liquid fraction rich in C 2+.
- the separation column T may have bottoms and / or packings.
- the aforementioned second C 2+ -rich liquid fraction is taken off via the line 10, in which a control valve e is provided, from the bottom of the separation column T and discharged from the process as so-called NGL (N [atural gas liquids) fraction and, if necessary for further use.
- NGL Natural gas liquids
- a partial stream of this fraction is partially evaporated in the heat exchanger E3 and fed via line 11 as a reboiler stream of the separation column T.
- the rectification separation T is at a higher pressure than the separation D1 of the partially evaporated natural gas 2 into a first C 1 - rich gas fraction 4 and a first C 2+ liquid fraction rich 3.
- the separation or separator D1 preferably a pressure between 15 and 25 bar and in the rectificatory separation T preferably a pressure between 30 and 40 bar realized.
- a pump P3 is to be provided in line 3.
- the recovered in the rectification separation T second Ci-rich gas fraction is withdrawn at the top of the separation column T via line 8 and in the heat exchanger E2 against the natural gas to be heated 1 'at least partially, but preferably completely reliquefied and via line 8', in which a control valve c is arranged, fed to a pump reservoir D2. This is via line section 7, in which also a control valve b is arranged, the one Partial flow of the first reliquefied C r rich fraction fed, which is not the separation column T is given as reflux.
- the C 2+ -depleted LNG product fraction is pumped by means of the pump P 4 to the desired discharge or pipeline pressure - this is generally between 50 and 150 bar and via line 9, in which also a control valve a is discharged from the process.
- the second C 2+ -rich liquid fraction is subjected to a (second) rectification C 2 / C 3 separation in the separation column T '.
- a C 3+ -rich LPG product fraction is withdrawn via line 18, a C 3+ -rich LPG product fraction and possibly fed to further processing or use.
- a partial stream of this fraction is partially evaporated in the heat exchanger E5 and fed via line 19 as a reboiler stream of the separation column T '.
- a C 2 / C 3 -rich gas fraction is withdrawn via line 12, at least partially condensed in the side reboiler E 4, which is connected via lines 13 to the separation column T and then fed via line 14 to the pump reservoir D3.
- the condensed C 2 / C 3 -rich fraction via line 15 of the pump P 5 is supplied and pumped by this to the desired discharge pressure.
- a secondary stream of the pumped fraction is fed via line 16 and control valve f the head of the separation column T 1 as reflux, while the main flow of the pumped fraction via line 17 is discharged from the process and optionally fed to further use or processing.
- the heat exchanger required for this purpose can be provided for example between the pump P3 and the separation column T.
- a temperature of about -100 ° C is required.
- Ambient temperature - or - thermodynamically equivalent - compression can be dispensed with.
- the inventive method for separating a C 2+ -rich fraction of liquefied natural gas (LNG) allows the realization of high ethane exploit while dispensing with expensive compressors.
