Definitions
- the invention relates to a method for cooling a hydrocarbon-rich fraction, in particular natural gas, wherein
- the refrigerant comprises at least nitrogen and / or carbon dioxide and / or methane and / or C 2+ hydrocarbons
- the turbo-compressor as a primary sealing gas, a partial flow of the refrigerant and / or an external gas or gas mixture, comprising substantially nitrogen and / or methane, and are fed as a secondary barrier gas nitrogen.
- C 2+ hydrocarbons means the aforementioned components C 2 H 4 , C 2 H 6 , C 3 H 6 , C 3 H 8 , i / nC 4 H 10 and i / nC 5 H 12 to understand, etc.
- the inventory of the refrigeration cycle is kept constant in terms of quantity and molar composition.
- it inevitably leads to leakage of the refrigeration cycle or to the entry of additional material or component streams in the refrigeration cycle.
- the shaft seals of the compressor to be provided for the compression of the refrigerant compressor and their barrier gas supply.
- Gas seal is a mixture of refrigerant and nitrogen. This mixture is generally removed to the plant torch, resulting in a loss of refrigerant.
- Object of the present invention is to provide a generic method for cooling a hydrocarbon-rich fraction, which avoids the aforementioned disadvantages.
- a method for cooling a hydrocarbon-rich fraction is proposed, which is characterized in that
- Refrigerant circuit at least temporarily at least one nitrogen-rich stream is removed.
- the nitrogen-rich stream is preferably at the cold end of
- the removal of the nitrogen-rich stream takes place in particular when the nitrogen and / or methane content of the circulating in the refrigerant circuit refrigerant exceeds a predetermined threshold.
- Prevent refrigeration circuit with nitrogen and / or methane With nitrogen and / or methane.
- the desired ratio between these components and the C 2+ hydrocarbons thus remains essentially unchanged.
- the withdrawn nitrogen-rich stream has a proportion of C 2+ hydrocarbons of less than 2 mol%, preferably less than 0.5 mol%.
- the inventive method for cooling a hydrocarbon-rich fraction allows a reduction in losses of C 2+ hydrocarbons or C 2+
- a further advantageous embodiment of the method according to the invention for cooling a hydrocarbon-rich fraction is characterized in that, if the hydrocarbon-rich fraction liquefies, at least one Storage tank supplied and withdrawn from this boil-off gas fraction, the withdrawn nitrogen-rich stream is at least partially mixed with the boil-off gas fraction and / or flared.
- boil-off gas fraction is to be understood here as meaning the liquefied natural gas (LNG) evaporating due to the introduction of heat into a storage container and the displacement gas arising during the LNG introduction into the storage container.
- Raising the sealing gas pressure is supplied to the suction side.
- turbo compressor as the primary sealing gas, an external gas or
- Gas mixture comprising essentially nitrogen and / or methane, is supplied, this gas (mixture) advantageously from one within the
- Cooling incurred and / or existing fraction generated For example, a partial flow of the compressed boil-off gas fraction and / or a partial flow of the process nitrogen can be used.
- Embodiment which shows a natural gas liquefaction process, explained in more detail.
- the natural gas to be cooled and liquefied is a
- Heat exchanger E supplied in which it is cooled and liquefied against the refrigerant of a refrigeration cycle, which will be discussed in more detail below.
- a storage tank S is supplied.
- a resulting within the storage tank S Boil-off gas fraction is withdrawn via line 4, preferably warmed in the heat exchanger E against the natural gas to be cooled 1 and then via line 5 - if necessary after prior compression by a boil-off gas compressor C2 - as so-called.
- One Partial flow of this fraction can be supplied via the line sections 23 and 18 to be described later turbo compressor C1 as the primary sealing gas.
- the circulating refrigerant within the refrigeration cycle has, for example, the components nitrogen, methane and C 2+ hydrocarbons.
- the compression of this refrigerant takes place in a one-stage or multi-stage, one or more gas-lubricated sliding ring seals having turbo compressor C1.
- the compressed to the desired cycle pressure refrigerant is fed via line 10 to the heat exchanger E and cooled in this against itself. Via line 1 1, the cooled refrigerant is withdrawn from the heat exchanger E and relaxed in the expansion valve a karlteleistend.
- the expanded refrigerant is then fed via line 12 to a separator D1 and in this separated into a liquid C 2+ -hydrocarbon-rich fraction 13 and in a substantially exclusively nitrogen and methane-containing gaseous fraction 14.
- the two aforementioned fractions are reunited immediately before the heat exchanger E and countercurrent to the natural gas stream 1 to be cooled and the refrigerant stream 10 to be cooled by the
- Separator D1 separated into a liquid C 2 + -hydrocarbon-rich fraction 13 and in a substantially exclusively nitrogen and methane-containing gaseous fraction 14, wherein the liquid C 2+ -hydrocarbon-rich fraction 13 then in the dashed line valve a 'on the Evaporating pressure of the refrigerant is released.
- Components are enriched during the first relaxation in the gas phase. As a result, the process can be made more selective.
- a partial flow of the refrigerant circulating in the refrigeration cycle and / or an external gas or gas mixture, which essentially comprises nitrogen and / or methane, are fed to the turbocompressor C1 as the primary seal gas.
- This supply of a partial flow of the refrigerant via line 17, in which a control valve c

Furthermore, the turbo-compressor C is fed as a secondary barrier gas nitrogen or a nitrogen-rich fraction. For the sake of clarity, this is not shown in FIG.
- the components nitrogen and / or methane within the refrigeration cycle can be removed from the refrigeration cycle via line 21, in which a control valve b is arranged.
- a control valve b By providing the above-described separator D1 ensures that the withdrawn via line 21 from the refrigeration cycle nitrogen-rich stream 21 contains virtually no C 2 + - hydrocarbons. Their losses within the refrigeration cycle are therefore negligible.
- the nitrogen-rich stream 21 can also be flared.
- the removal of the nitrogen-rich stream 21 takes place at the cold end of the refrigeration cycle. Alternatively, however, other removal points are conceivable.
- the removal of the nitrogen-rich stream 21 may be continuous or discontinuous. The removal of the nitrogen-rich stream 21 takes place in particular as soon as the nitrogen and / or methane content of the circulating in the refrigerant circuit refrigerant a predetermined
- Threshold exceeds. For this it is necessary to know the composition of the
- the purge gas mixture withdrawn from the turbo-compressor C1 via the primary discharge of its gas seal may be the compressor or, in the case of a multi-stage compression, the first compressor stage suction side, preferably via the above-described container D2, are fed again; This is shown in the figure 1 by the line 20.
- the above-described recirculation of the purge gas mixture withdrawn via the primary discharge before the turbo-compressor C1 or its first compressor stage can directly by raising the primary
- Blocking gas mixture before the turbo compressor or its first compressor stage can also be realized using an ejector or other compressor.
- drive current for the ejector can this purpose refrigerant from the pressure side of the
