Definitions
- the invention relates to a method for separating a helium-rich fraction from a liquefied natural gas stream.
- Helium is usually obtained in large quantities from natural gas or from natural gas fractions, such as those found in the so-called LNG baseload plants, ie from a gas mixture consisting essentially of methane, a high proportion of nitrogen and hydrocarbons.
- Flash gas of the LNG storage tank is concentrated.
- 1 "cold end" of LNG baseload plants
- the high pressure liquefied natural gas whose temperature is almost fixed due to the refrigerant of the LNG baseload plant, initially throttled to a mean pressure between 3 and 10 bar
- the resulting helium-rich flash gas typically a helium content between 5% and 20% - warmed up and fed to a helium recovery plant as a feed fraction.
- the helium-rich flash gas z. B. against a purified, high pressure natural gas stream - which is withdrawn before the actual liquefaction part of the liquefaction process and thus from the so-called.
- the amount of this additional natural gas flow is in such a way that no noticeable change in the liquefaction capacity of the LNG baseload plant takes place, which is the case in a wide volume flow range.
- Object of the present invention is to provide a generic method for separating a helium-rich fraction from a liquefied natural gas stream, which avoids the aforementioned disadvantages.
- a generic method which comprises the following method steps: a) decompression of the liquefied natural gas stream and separation of a helium-rich fraction, b) heating of the helium-rich fraction against a natural gas stream to be cooled and liquefied and c) feeding in heat exchange against the helium-rich fraction to be liquefied liquefied natural gas stream to the liquefied liquefied
- the flow rate of the aforementioned natural gas stream to be cooled and liquefied is preferably adjusted so that there is no significant change in the liquefaction capacity of the LNG baseload plant.
- the inventive method now makes it possible to meet a wide variety of helium and nitrogen contents in the liquefied natural gas stream and the liquefied natural gas stream.
- the helium-rich fraction as well as the natural gas stream to be cooled and liquefied, which are brought into heat exchange with each other, can now be heated or cooled against each other in a targeted temperature-controlled manner. This allows the conditions for the relaxation of the liquefied
- the mass flow of the helium-rich fraction fed to the heat exchange and / or the mass flow of the natural gas flow supplied, cooled and liquefied be varied such that the helium yield is increased .
- the helium-rich fraction remains substantially constant and / or maximized.
- the fuel gas fraction obtained in the fuel gas separation is heated against the natural gas stream to be cooled and liquefied
- the heat exchange between the helium-rich fraction to be heated and the natural gas stream to be cooled and liquefied takes place in at least one wound heat exchanger and / or at least one TEMA heat exchanger,
- Via line 1 is - as shown in Figure 1 - a liquefied natural gas stream, which was obtained in any natural gas liquefaction process, introduced, relaxed in the valve a to a pressure between 3 and 10 bar and then fed via line 2 to a separator D. At the top of this separator D, a helium-rich gas fraction is withdrawn via line 3.
- the helium-rich gas fraction is heated in the heat exchanger E, which is preferably a wound heat exchanger or a TEMA heat exchanger, against a natural gas stream to be cooled and liquefied, which will be discussed in more detail below and then fed via line 4 for further use, such as a process in which a pure-helium fraction is recovered.
- the heat exchanger E which is preferably a wound heat exchanger or a TEMA heat exchanger
- a helium-depleted liquid fraction is withdrawn via line 5, expanded in the valve b to a pressure between 1 and 5 bar and via line 6 their further use - possibly after prior promotion by means of pump and caching in a storage tank at Atmospheric pressure - fed.
- the heat exchanger E is supplied with the mentioned natural gas flow to be cooled and liquefied.
- This gaseous natural gas stream is withdrawn from the natural gas liquefaction process, for example after the separation of heavy hydrocarbon which is normally required.
- the amount of this natural gas stream is preferably adjusted so that the helium separation D does not result in a noticeable change in the liquefaction capacity of the LNG baseload plant.
- bypass lines 7 and 11 are shown in each of which a control valve d and e is arranged.
- the guided in the lines 3 and 9 fractions can be passed completely or at least partially to the heat exchanger E.
- the mass flow of the natural gas stream supplied to the heat exchanger E via line 9 can now be varied by means of the expansion valve c and / or the bypass line 11.
- maximum helium yields or quantities in the helium-rich fraction 3 withdrawn at the top of the separator D can be set or achieved for different compositions of the liquefied natural gas stream.
- the subcooling temperature of the latter stream is adjusted after the heat exchange E to maximize the helium yield in the helium-rich fraction 3.
- the aim of this procedure is to adjust the conditions in the separator D, so the total enthalpy of the mixture so that even with different compositions of the natural gas streams 1 and 9, a maximum helium yield in the helium-rich flash gas 3 and 4 is achieved and simultaneously the production of LNG Baseload process is not or only insignificantly affected. In this way an optimal feed fraction can be provided for a downstream process for pure helium 'recovery.
- the heat exchanger E If comparatively small temperature differences between 5 and 30 K occur in the heat exchanger E, then this will preferably be designed as a plate exchanger. In the case of larger temperature differences, it is advantageous to realize the heat exchanger E as a wound heat exchanger and / or TEMA heat exchanger.
- the bypass line 11 can be used for a maximum helium flow rate.
- Yield required subcooling temperature of the guided over the line sections 9 and 10 natural gas stream at the output of the heat exchanger E can be adjusted and regulated.
- more than 97% can be the win 'in the present to be liquefied natural gas stream helium.
- the inventive method for separating a helium-rich fraction from a liquefied natural gas stream thus makes it possible to maximize the helium yields of even the most varied liquefied natural gas streams.
- the required regulatory effort is limited, so that the realization of the method according to the invention leads only to insignificant additional costs.
