Definitions
- the invention relates to a process for liquefying a hydrocarbon-rich fraction, in particular natural gas, wherein
- the natural gas Before liquefaction, the natural gas is usually purified by means of a chemical wash, for example an amine wash, of sour gas components such as C0 2 and H 2 S. This saturates the natural gas with water (steam).

- sour gas components such as C0 2 and H 2 S. This saturates the natural gas with water (steam).

- DE 10 2006 021 620 therefore proposes a development of the process disclosed in DE 197 22 490 for liquefying a hydrocarbon-rich fraction, in which a partial flow of the liquid fraction of the refrigerant
- Pre-cooling of the hydrocarbon-rich fraction to be liquefied prior to their introduction into the water separation is used.
- the object of the present invention is to provide a generic process for liquefying a hydrocarbon-rich fraction, which makes it possible to pre-cool the hydrocarbon-rich fraction to be liquefied without using a complete precooling, ie without an additional compressor prior to drying.
- the hydrocarbon-rich fraction should be pre-cooled to a temperature of at most 10 ° C, preferably at most 5 ° C above the hydrate temperature, without the wet hydrocarbon-rich fraction comes into thermal contact with temperatures below the hydrate point.
- a generic method for liquefying a hydrocarbon-rich fraction is proposed, which is characterized in that the heat exchange between the liquid fraction and the hydrocarbon-rich fraction to be liquefied takes place via at least one heat exchange system.
- the inventive method for liquefying a hydrocarbon-rich fraction further forming is proposed that a partial flow of the liquid fraction of the refrigerant to a pressure of at least 0.3 bar, preferably at least 0.7 bar above the suction pressure of the second or last stage compressor relaxed and only the case accumulating liquid fraction is used for the precooling of the hydrocarbon-rich fraction to be liquefied prior to its introduction into the water separation.
- the pre-cooling of the hydrocarbon-rich fraction to be liquefied before it is fed into the water separation takes place against a partial flow of the liquid fraction resulting from the partial condensation of the compressed refrigerant.
- the heat exchange between this liquid fraction and the hydrocarbon-rich fraction to be liquefied via a
- Heat exchange system realized.
- the heat exchange system is used for the indirect heat transfer between the hydrocarbon-rich fraction to be liquefied and the sliding evaporating refrigerant.
- the term "heat exchange system” is to be understood as any system in which an indirect heat transfer between at least two media takes place by means of a heat transfer fluid. Such a heat exchange system is known for example from US Patent 2,119,091.
- Such heat exchange systems preferably use a boiling, in the temperature range between 0 and 30 ° C liquid present as heat transfer fluid, which may be, for example, ethane, ethylene, propane, propylene, butane, carbon dioxide or ammonia.
- the heat exchange system is preferably composed of two straight tube bundles, two coiled heat exchangers, two plate exchangers or any one of them
- Hydrocarbon-rich fraction the desired heat conversion.
- the heat transfer fluid operates at a constant boiling temperature and thus at the same temperature. Even if the condensation of the
- the hydrocarbon-rich fraction 2 to be liquefied is fed to a heat exchange system E4 and pre-cooled therein to a temperature of at most 10 ° C, preferably at most 5 ° C above its hydrate temperature.
- the so pre-cooled is fed to a heat exchange system E4 and pre-cooled therein to a temperature of at most 10 ° C, preferably at most 5 ° C above its hydrate temperature.
- Hydrocarbon-rich fraction 3 is fed to a separator D4, in whose sump the condensed water 4 is obtained.
- the hydrocarbon-rich fraction 5 withdrawn at the top of the precipitator D4 will now be referred to only as
- a zeolitic molecular sieve is usually used as the adsorbent.
- the thus pretreated to be liquefied hydrocarbon-rich fraction 6 is then in
- Heat exchanger E is cooled against the still to be explained refrigerant circuit, liquefied and possibly supercooled, so that via line 7 in the case of natural gas liquefaction, an LNG product stream can be withdrawn.
- Mixture refrigerant circuit Such mixture refrigerant cycles usually have nitrogen and at least one C 1+ hydrocarbon as refrigerant.
- the refrigerant to be compressed 10 is in the first compressor stage C1 to a
- the cold-expanded refrigerant 16 is then completely evaporated in the heat exchanger E against the hydrocarbon-rich fraction to be liquefied 6 and again fed to the separator D1 upstream of the first compressor stage C1; this serves to protect the compressor stage C1, since liquid components entrained in it are possibly separated off.
- the aforementioned gas fraction 40 is partially condensed and im Separator D6 separated into a further gas fraction 41 and another liquid fraction 42.
- the gas fraction 41 is cooled in the liquefaction and subcooling b and c of the heat exchanger E 'and partially condensed. Subsequently, it is depressurized in the expansion valve V7 and fully evaporated in countercurrent to the hydrocarbon-rich fraction 6 to be liquefied and possibly to be supercooled.
- the liquid fraction 42 obtained in the separator D6 is further cooled in the liquefaction zone b of the heat exchanger E ', cooled in a high-performance manner in the expansion valve V6 and countercurrently to be liquefied
