Definitions
- the invention relates to a method for liquefying a hydrocarbon-rich stream, in particular a natural gas stream, wherein the liquefaction of the hydrocarbon-rich stream takes place against a consisting of three refrigerant mixture cycles refrigerant mixed cycle cascade.
- first mixed refrigerant cycle should always be understood as meaning a carbon dioxide refrigerant circuit.
- German Patent Application 197 16 415 A generic method for liquefying a hydrocarbon-rich stream is known from German Patent Application 197 16 415. With the citation of German Patent Application 197 16 415 whose disclosure content is included in the disclosure of the present patent application.
- Natural gas liquefaction plants are designed either as so-called LNG baseload plants, ie plants for the liquefaction of natural gas to supply natural gas as primary energy, or as peak shaving plants, ie plants for the liquefaction of natural gas to cover the peak demand.
- LNG baseload plants are operated with refrigeration circuits consisting of hydrocarbon mixtures. These mixture cycles are more energy efficient than expander circuits and allow for the large liquefaction of baseload plants accordingly relatively low energy consumption.
- the first mixture cycle of the precooling, the second mixture cycle of the liquefaction and the third mixture cycle of the supercooling of the hydrocarbon-rich stream or natural gas have basically been used.
- the refrigerant mixture of the first refrigerant mixture cycle used for precooling is usually evaporated to two or more different pressure levels in the above-described generic liquefaction. This achieves a good adaptation of the cooling supply to the cooling requirement of the warm process streams and thus reduces energy consumption. Therefore, in particular for so-called base-load systems or processes, a single-stage precooling is unusual due to the increased energy consumption associated with it.
- Object of the present invention is to provide a generic method which avoids the aforementioned disadvantages.
- a generic method for liquefying a hydrocarbon-rich stream is proposed, which is characterized in that the first and the second mixed refrigerant cycle precooling and the third refrigerant mixture cycle of liquefaction and supercooling of the hydrocarbon-rich stream is used.
- the third refrigerant mixture cycle is designed as a two-stage refrigerant mixture cycle
- the power consumption of the compressor of the first and second refrigerant mixture circuit is identical or substantially identical is the two-stage, third refrigerant mixture circuit to the power consumption of the compressor, 'wherein preferably all the compressors of the refrigerant mixture circuits have an identical or substantially identical power consumption,
- pre-cooling is to be understood as cooling the liquefied hydrocarbon-rich stream to a temperature of at least -30 0 C to -70 0 C, preferably -40 0 C to -60 0 C.
- the suction pressure of the two precooling circuits in the liquefaction process according to the invention can be significantly increased, namely typically to 5 bara and higher.
- the suction pressure of the low-pressure stage of a two-stage precooling circuit is typically 2 to 3 bara.
- the method according to the invention makes it possible to realize more compact systems or processes. Compared with liquefaction processes in which only two mixture cycles are used, the inventive method with three mixture cycles also has a lower specific energy consumption.
- the hydrocarbon-rich stream to be liquefied is in the heat exchanger E1 against the evaporating mixed refrigerant stream 2b of the first mixture cycle 2a to 2c cooled. Subsequently, the hydrocarbon-rich stream is fed via line 1a to the heat exchanger E2 and further cooled in this against the evaporating refrigerant mixture stream 3b of the second mixture circuit 3a to 3c.
- the cooled hydrocarbon-rich stream At the outlet of the heat exchanger E2 is the cooled hydrocarbon-rich stream at a temperature of -30 0 C to -70 0 C, preferably -40 0 C to -60 0 C before. It is now fed via line 1b to a separating unit S shown only as a black box.
- the hydrocarbon-rich stream to be liquefied is then fed via line 1d to a third heat exchanger E3 and in this liquefied and undercooled against the evaporating refrigerant mixture stream 4b of the third refrigeration cycle 4a to 4c.
- the supercooled liquid product is then fed via line 1e to its further use and / or (intermediate) storage.
- the two refrigerant mixture circuits 2a to 2c and 3a to 3c used for pre-cooling the hydrocarbon-rich stream are in each case single-stage refrigerant mixture cycles.
- the refrigerant mixtures compressed in the respective cycle compressor V2 or V3 are conducted via the line 2a or 3a through the heat exchanger E1 - in the case of the first refrigerant mixture cycle - or through both heat exchangers E1 and E2 - in the case of the second refrigerant mixture cycle.
- the mixed refrigerant stream is evaporated in the heat exchanger E1 or E2 against cooled process streams and then fed via line 2c and 3c again to the cycle compressors V2 and V3.
- the third refrigerant mixture cycle in which the compressed refrigerant mixture 4a is supplied after cooling in the heat exchangers E1, E ⁇ 2 and E3 via line 4b a relaxation device c, relaxed in this, then evaporated in the heat exchanger E3 against cooling process streams and then via line 4c the Input of the low-pressure compressor stage V4, which is connected downstream of the high-pressure compressor stage V4 1 , is supplied.
- compressors V2, V3, V4 and V4 'downstream cooler or heat exchangers in which the refrigerant mixture against a cooling medium -.
- the refrigerant mixture of the second refrigerant mixture cycle is usually partially condensed after compression at least against a cooling medium - for example. Water or air.
- the power consumption of the compressors V2 and V3 of the first and second refrigerant mixture circuits 2a-2b and 3a-3b may be identical or substantially identical to the power consumption of the compressors V4 and V4 'of the two-stage, third refrigerant mixture cycle 4a-4b be designed.
- Mixed refrigerant circuits 2a-2b, 3a-3b and 4a-4b have an identical or substantially identical power consumption.
- the power consumption of the compressors V2 and V3 of the first and second refrigerant mixture circuits 2a-2b and 3a-3b may be identical or substantially identical to the power consumption of each of the two
- this embodiment of the method according to the invention preferably three identical drives A2 / 3, A4 and A4 1 are used, the drive A2 / 3 the Verêtm V2 and V3 and the drives A4 and A4 'the compressors V4 and V4' are assigned.
