Definitions
- the present invention relates to a process for purifying a gas containing hydrocarbons heavier than methane, for example natural gas or a gas associated with the production of oil or a flare gas or a gaseous refinery effluent.
- a gas containing hydrocarbons heavier than methane for example natural gas or a gas associated with the production of oil or a flare gas or a gaseous refinery effluent.
- NNLs Natural Gas Liquids
- LPGs liquefied petroleum gases
- Some alternative membrane technologies make it possible to concentrate the liquid derivatives of natural gas on the residue side (retentate) of a membrane.
- the applicant has, for example, developed a polymer fiber, resistant to liquid formation and selective towards methane with respect to hydrocarbons having more than two or more carbon atoms: light hydrocarbons (and hydrogen) while the partial pressure of heavier hydrocarbons increases on the high pressure side (residual side of the membrane) thus resulting in a partial or complete condensation of heavy hydrocarbons.
- the inventors of the present invention have developed a solution allowing the separation of a gas stream into a fraction enriched in methane and a fraction enriched in C2 hydrocarbons and higher by minimizing methane losses during this withdrawal and while minimizing the costs of deploying this type of process
- the present invention relates to a method for purifying a natural gas feed stream comprising methane, and hydrocarbons having at least two carbon atoms, comprising the following steps:
- the subject of the invention is also:
- step f A method as defined above, characterized in that the heated stream from step f) is recycled by mixing with the feed stream.
- step b) is mixed with said at least a portion of the liquid stream from step d) before step e ).
- step c) A process as defined above, characterized in that at least a portion of the permeate stream enriched in methane from step c) is heated by introduction into the heat exchanger implemented in step a) to against the current of the supply current to cool the latter.
- step d characterized in that at least a portion of the liquid stream from step d) is introduced into a third phase separator pot to produce at least two phases including a liquid stream and a current gaseous.
- feed stream refers to any composition containing hydrocarbons including at least methane.
- the heat exchanger may be any heat exchanger, unit or other arrangement adapted to allow the passage of a number of flows, and thus allow a direct or indirect heat exchange between one or more lines of refrigerant, and a or multiple feed streams.
- the purified stream (liquid fraction of the residue) comprises at least 50 mol% of hydrocarbons other than methane.
- the membrane separation unit implemented during step c) has a greater selectivity for methane than for hydrocarbons having at least two carbon atoms, preferably having at least three carbon atoms and functions in the presence of liquid .
- the methane or even the hydrogen are found in the permeate stream leaving the membrane unit while the heavier hydrocarbons than the methane are on the residue side (retentate), generating a partial or total condensation of the hydrocarbon-rich liquid residue stream comprising at least two carbon atoms.
- the present invention consists in the combination of a membrane unit with partial or total condensation on the residue side (retentate) and a heat exchanger between the feed gas cooled by the expanded gaseous fraction or the relaxed liquid fraction of said residue in order to perform an efficient separation between methane and heavier hydrocarbons.
- the lower temperature thus obtained for the feed stream makes it possible to increase the rate of formation of liquid hydrocarbons.
- a natural gas feed stream 1 is introduced into a heat exchanger 2 at a temperature T1.
- the feed stream 1 may contain methane, ethane, propane, hydrocarbons having at least four carbon atoms, CO2, aromatics, nitrogen, water, sulfur compounds ( H2S for example).
- the feed stream 1 can be compressed via a compressor 24 for example, so that the pressure is sufficient for the proper implementation of the method according to the invention.
- a partially condensed stream 3 exits the heat exchanger 2 at a temperature T2 less than T1.
- the stream 3 is introduced into a phase separator pot 4 from which there emerges a liquid stream 5 'rich in water, a hydrocarbon-rich liquid stream 5 having at least two carbon atoms and a gaseous stream 6 enriched in methane.
- the current 3 may have been expanded to a current 3 ', via a Thomson Joule valve 26 for example, prior to its entry into the separator pot 4.
- the gas stream 6 is then introduced into a membrane separation unit 7 having a greater methane selectivity than for hydrocarbons having more than two carbon atoms and operating in the presence of liquid formation on the residue side (retentate).
- the stream is separated into a gaseous permeate stream 8 enriched in methane and whose pressure is lower than the pressure of stream 6 and a residue stream 9 partially condensed and enriched in at least one hydrocarbon having more than two atoms. of carbons.
- the stream 9 is introduced into a phase separator pot 10. There emerges a liquid stream 1 1 rich in hydrocarbons having at least two carbon atoms and a gas stream 12.
- the gas stream 12 may then, at least in part, be reheated in the heat exchanger 2 to a temperature fairly close to T1 (that is, at a temperature T4 greater than T2 and at least between T2 and T1).
- the stream 12 heats up in the heat exchanger 2 against the direction of the feed stream 1, which in turn is cooled to the temperature T2.
- the stream 15 may then optionally be mixed with the feed stream 1 to be recycled. This recycling can take place after passage in a dedicated compressor according to the needs and operating conditions if a treated gas compressor 24 is not used.
- the stream 12 Prior to entering the heat exchanger 2, the stream 12 is expanded 14 by means of a Joule-Thomson valve 13.
- liquid streams 5 and 1 1, at least partly, independently or after having been mixed 17 and optionally expanded via a Joule Thomson valve 36, in the heat exchanger 2 in order to be reheated 27 and partially (or totally) vaporized and serve to cool the feed stream 1.
- Part of the liquid stream 1 1 can be introduced into a phase separator pot 21 after having been expanded via a Joule Thomson valve 28. It emerges from this phase separator pot 21, a liquid phase 22 enriched in heavy hydrocarbons and a phase gaseous 23.
- the gas phase 23 and / or at least a portion 18 of the permeate stream 8 enriched in methane leaving the membrane unit 7 can be introduced (after mixing or not), after optional expansion 19, in the heat exchanger 2 so serve as a source of cold for cooling the feed gas 1.
- At least one other portion 31 of this stream 29 could be again mixed with the portion 32 of the permeate stream 8 that would not have been sent to the heat exchanger 2.
