Definitions
- the invention relates to a method for liquefying a hydrocarbon-rich stream, in particular a stream of natural gas, where the liquefaction of the hydrocarbon-rich stream takes place countercurrent to a refrigerant mixture cascade consisting of two refrigerant mixture cycles and where the first refrigerant mixture cycle is used for precooling and the second refrigerant mixture cycle is used for liquefying and supercooling the hydrocarbon-rich stream to be liquefied.
- the invention further relates to a method for liquefying a hydrocarbon-rich stream, in particular a stream of natural gas, where the liquefaction of the hydrocarbon-rich stream takes place countercurrent to a refrigerant mixture cycle cascade consisting of three refrigerant mixture cycles and where the first of the three refrigerant mixture cycles is used for precooling, the second refrigerant mixture cycle is used for the actual liquefaction and the third refrigerant mixture cycle for supercooling the liquefied hydrocarbon-rich stream.
- precooling should be understood to mean the cooling of the hydrocarbon-rich stream down to a temperature at which the separation of heavy, or higher-boiling, hydrocarbons takes place.
- the subsequent further cooling of the hydrocarbon-rich stream to be liquefied hereinafter comes under the term “liquefaction”.
- the object of the present invention is to specify generic methods for liquefying a hydrocarbon-rich stream in which the aforementioned problems can be avoided.
- the number of heat exchangers, or heat exchanger blocks, for the same process task can be reduced substantially.
- the required expenditure for pipelines can be reduced.
- the number of blocks per heat exchanger type can be kept below 16 at a liquefaction capacity up to 10 mtpa, preferably between 2 and 8 blocks. This allows symmetrical pipelines at an appropriate expenditure.
- FIG. 1 shows a natural gas liquefaction method in which the liquefaction takes place countercurrent to a refrigerant mixture cycle consisting of two refrigerant mixture cycles;
- FIG. 2 shows a natural gas liquefaction method in which the liquefaction takes place countercurrent to a refrigerant mixture cycle consisting of three refrigerant mixture cycles;
- FIG. 3 shows a natural gas liquefaction method as explained using FIG. 2 and in which at least one refrigerant mixture partial stream from the second refrigerant mixture cycle is used for the precooling of the natural gas;
- FIGS. 4 / 5 show natural gas liquefaction methods as explained using FIG. 2 in which the cooling of the refrigerant mixture of the second and ternary refrigerant mixture cycles takes place in dual-stream exchangers.
- the natural gas stream to be cooled and liquefied is taken over line 1 to a first heat exchanger E 1 .
- the natural gas stream is cooled countercurrent to a partial stream P 3 of the refrigerant mixture of the first refrigerant mixture cycle.
- the natural gas stream is taken over line 2 to a second heat exchanger E 2 in which it is cooled in succession countercurrent to two partial streams P 5 and P 7 of the refrigerant mixture of the first refrigerant mixture cycle.
- the natural gas stream cooled in this way is subsequently taken over line 3 to a further heat exchanger E 5 and liquefied in the exchanger countercurrent to the refrigerant mixture L 2 of the second refrigerant mixture cycle and supercooled as necessary. Subsequently to this the liquefied natural gas stream (LNG) is taken over line 4 to its further use and/or to storage.
- LNG liquefied natural gas stream
- the last described liquefaction and supercooling of the precooled natural gas stream takes place in the case of the embodiment shown in FIG. 1 countercurrent to the second refrigerant mixture cycle L 1 to L 4 of the refrigerant mixture circuit cascade, where the refrigerant mixture compressed by means of single- or multi-stage compression LV is first taken to an aftercooler LK and subsequently over line 4 to a heat exchanger E 3 .
- a cooling and liquefaction of the refrigerant mixture of the second refrigerant mixture cycle takes place in the exchanger countercurrent to partial streams P 9 , P 11 and P 13 of the refrigerant mixture of the first refrigerant mixture cycle, which are available at suitable temperature levels.
- the thus cooled and liquefied refrigerant mixture of the second refrigerant mixture cycle is subsequently taken over line L 1 to heat exchanger E 5 already mentioned, supercooled countercurrent to itself, drawn off over line L 2 from heat exchanger E 5 , expanded and again taken through heat exchanger E 5 countercurrent to the natural gas stream to be liquefied and if necessary supercooled. Subsequently the refrigerant mixture is drawn off over line L 3 and taken to the single- or multi-stage circuit compressor LV already mentioned.
- the refrigerant mixture stream compressed in compression PV is taken over line P 1 to a condenser PK and subsequently over line P 2 to the first of three heat exchangers E 4 A, E 4 B and E 4 C.
- partial streams of the refrigerant mixture at suitable temperature levels are drawn off through the lines P 3 , P 5 or P 7 , expanded and subsequently—as already described—taken through heat exchangers E 1 and E 2 for the purpose of precooling the natural gas stream 1 or 2 which is to be liquefied.
- partial streams P 15 , P 17 and P 19 are drawn off from them in turn, expanded and taken countercurrent through the three aforementioned heat exchangers E 4 A, E 4 B or E 4 C. These partial streams are subsequently in turn admixed to the particular streams from which they were drawn off over lines P 16 , P 18 and P 20 before compression PV.
- partial streams are similarly drawn off from the three refrigerant mixture partial streams P 3 , P 5 and P 7 over lines P 9 , P 11 and P 13 , expanded and taken through the heat exchanger E 3 countercurrent to the refrigerant mixture L 4 of the second refrigerant mixture cycle.
- These refrigerant mixture partial streams are also subsequently admixed over lines P 10 , P 12 and P 14 to the refrigerant mixture partial streams in the lines P 4 , P 6 and P 8 before compression PV.
- FIG. 2 differs from the one shown in FIG. 1 in that an additional refrigerant mixture stream is now provided for the supercooling of the liquefied natural gas stream. Consequently, in what follows only the differences between the embodiments shown in FIGS. 1 and 2 will be discussed.
- the liquefaction of the natural gas stream precooled in heat exchangers E 1 and E 2 takes place in heat exchanger E 5 countercurrent to the refrigerant mixture stream of the second refrigerant mixture cycle. Subsequently the liquefied natural gas stream is taken over line 4 to a further heat exchanger E 6 , supercooled in the heat exchanger countercurrent to the refrigerant mixture stream S 3 of the third refrigerant mixture cycle and subsequently taken over line 5 to its further use and/or storage.
- the refrigerant mixture of the third refrigerant mixture cycle is also initially compressed in a single- or multi-stage compression SV and taken to an aftercooler SK and subsequently to heat exchanger E 3 over line S 1 .
- the cooled refrigerant mixture of the third refrigerant mixture cycle is taken to heat exchanger E 5 over line S 2 , cooled further here, completely condensed and subsequently supercooled in heat exchanger E 6 .
- the supercooled refrigerant mixture is drawn off from the latter over line S 3 , expanded and again taken through heater exchanger E 6 countercurrent to the natural gas stream to be supercooled.
- the heated refrigerant mixture of the third refrigerant mixture cycle is again taken over line S 4 to compression SV, which has already been described.
- FIG. 3 shows an embodiment of the method in accordance with the invention in which a partial stream of the refrigerant mixture of the second refrigerant mixture cycle—in addition to the refrigerant mixture from the first refrigerant mixture cycle—is used for precooling the natural gas stream to be liquefied.
- a refrigerant mixture partial stream from the refrigerant mixture stream cooled in heat exchanger E 3 is drawn off over line L 5 , expanded and taken at a suitable temperature level through heat exchanger E 2 in counterflow to the natural gas stream 2 which is to be cooled.
- the heated refrigerant mixture partial stream is subsequently taken to compression LV over line L 6 .
- a further partial stream of refrigerant mixture L 1 of the second refrigerant mixture cycle cooled in heat exchanger E 3 is drawn off over line L 7 , expanded and taken to heat exchanger E 3 for the purpose of preparing refrigerant.
- This refrigerant mixture partial stream is taken over line L 8 to the compressor unit LV after passing through heat exchanger E 3 .
- FIGS. 4 and 5 show embodiments of the method in accordance with the invention in which the cooling of refrigerant mixture L 4 of the second refrigerant mixture cycle takes place countercurrent to refrigerant mixture partial streams from the first refrigerant mixture cycle Pa, Pa′, Pb or Pb′ and the cooling of refrigerant mixture S 1 from the third refrigerant mixture cycle takes place countercurrent to refrigerant mixture partial streams from the first refrigerant mixture cycle Pc, Pc′, Pd or Pd′ in dual-stream exchangers E 3 A, E 3 B, E 3 C or E 3 D.
- the dual-stream exchangers E 3 A, E 3 B, E 3 C or E 3 D are preferably configured as plate exchangers.
- This embodiment of the method in accordance with the invention for liquefying a hydrocarbon-rich stream has the advantage that all refrigerant mixture partial streams of the first refrigerant mixture circuit Pa, Pb, Pc and Pd are carried in separate flow passages of dual-stream exchangers E 3 A, E 3 B, E 3 C and E 3 D which are optimized for the particular task and thereby substantially improve performance, in particular at startup and at part load. Against this, there is the disadvantage that the greater number of heat exchanger models causes increased engineering expense.
- the embodiment shown in accordance with the invention of the method in FIG. 5 for liquefying a hydrocarbon-rich stream differs from the one shown in FIG. 4 only in that the refrigerant mixture of the second refrigerant mixture cycle is evaporated at two different temperature levels.
- the heat exchanger E 5 shown in FIG. 4 is divided into two heat exchangers E 5 A and E 5 B.
- inventive methods for liquefying a hydrocarbon-rich stream, in particular a natural gas stream in contrast to the known collective pipelines which in the event of different pressure drops cause faulty distribution because of the non-symmetrical pipelines, allow the realization of sufficiently symmetrical pipelines and thus appropriate equal distribution by avoiding different pressure drops.
- inventive methods reduce complexity with respect to the necessary heat exchangers since predominantly only two-stream exchangers are used; as a result a thermal imbalance can largely be avoided in the event of the failure of individual circuits.
