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 is against a consisting of three mixed refrigerant circuits refrigerant mixture cycle cascade, wherein the first of the three refrigerant mixture precooling, the second mixed refrigerant cycle of the liquefaction and the third refrigerant mixture cycle of the subcooling of the liquefied hydrocarbon-rich stream is used.
- first mixed refrigerant cycle 1 always means 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.
- liquefaction method basically serves the first ' mixture cycle of precooling, the second mixture circuit of the liquefaction and the third mixture cycle of supercooling of the hydrocarbon-rich stream or natural gas. Between the pre-cooling and the liquefaction takes place - if necessary - the separation of higher-boiling hydrocarbons instead. These are at least those components of the hydrocarbon-rich stream or natural gas to be liquefied which would freeze out on subsequent cooling - ie C 5 + hydrocarbons and aromatics. Often, in addition, those hydrocarbons, meaning propane and butane in particular, which would undesirably increase the calorific value of the liquefied natural gas, are separated off prior to liquefaction.
- compressor drives and in particular gas turbines are only available in discrete stages.
- gas turbines are only available in discrete stages.
- the use of three substantially identical or identical drives is often not appropriate.
- the process procedure according to the invention is large capacity advantage, in particular for single-stranded liquefaction plants.
- the inventive method for liquefying a hydrocarbon-rich stream further forming is proposed that the compressors of the first and second refrigerant mixture cycle and the compressor of the third
- Refrigerant mixture cycle can be driven by means of two substantially identical and / or equal power drives.
- This embodiment of the method according to the invention makes sense, in particular, when compressor drives are available that account for 50% of the required
- the hydrocarbon-rich stream to be liquefied is cooled in the heat exchanger E1 against the two evaporating refrigerant mixture partial streams 4b and 4d of the first mixture circuit 4a to 4e and the evaporating refrigerant partial stream 3d of the second mixture circuit 3a to 3e and then via line 1a a separation unit shown only as a black box S supplied.
- the partial stream drawn off via the lines 4d and 4e is dispensed with. Furthermore, the compressor V4 in this case, no side feed - as shown in the figure - on.
- the above-described C 3+ separation takes place, wherein the components separated from the hydrocarbon-rich stream to be liquefied are withdrawn from the separation unit S via the line 1 b.
- At least a partial flow of one of the two partial flows 3b and 3d of the second refrigerant mixture cycle 3a to 3e will normally be used for the provision of refrigeration in the separation unit S.
- the choice of which of the two Partial flows 3b and / or 3d, in turn, at least a partial flow is used for this refrigeration provision are determined by the required in the separation unit S temperature level (s).
- the hydrocarbon-rich stream to be liquefied is then fed via line 1c to a second heat exchanger E2 and liquefied therein against the evaporating refrigerant mixture substream 3b of the second refrigeration cycle 3a to 3b.
- the supercooled liquid product is then fed via line 1e to its further use and / or (intermediate) storage.
- the subcooling refrigeration cycle 2a to 2c now according to the invention two compressors V2 and V2 1 connected in series.
- the pre-cooling and the liquefaction refrigeration cycle have only one compressor V4 and V3 respectively.
- the compressors V2, V2 ⁇ V3 and V4 used are identical or identical in terms of their performance according to the invention
- each compressor V2, V2 ', V3 and V4 can be provided by an identical or substantially identical drive A2, A2', A3 and A4. ' .
- each must be 'compressors V2, V2 1, V3 and V4 and compressor drive A2, A2 1, A3 and A4 25%, to provide at least 23-27% of the total power.
- the drives A2, A2 ⁇ A3 and A4 for the compressors V2, V2 ', V3 and V4 are preferably gas, steam turbines and / or electric motors.
- compressors V2, V2 1 , V3 and V4 downstream cooler or heat exchangers in which the refrigerant mixture against a cooling medium - eg. Water - cooled and in the case of the first refrigerant (mixture) circuit 4a to 4e is condensed.
- the compressed in the compressor V4 refrigerant mixture of the first mixture cycle is supplied via the line 4a to the heat exchanger E1 and divided into this after cooling in two partial streams 4b and 4d.
- the refrigerant mixture in these partial streams 4b and 4d is evaporated after relaxation in the valves d and e or investigationssvprraumen at different pressure levels in the heat exchanger E1 and then via the line 4c and 4e the compressor V4 before the first stage (part stream 4c) or supplied at an intermediate pressure level (partial flow 4e).
- the compressed in the compressor V3 refrigerant mixture of the second refrigeration circuit 3a to 3e is passed through line 3a through the heat exchangers E1 and E2 and cooled in this.
- the partial stream 3b of this mixed refrigerant stream, which is passed through the heat exchanger E2, is vaporized after relaxation in the valve b in the heat exchanger E2 against the process streams to be cooled and then fed via line 3c to the input stage of the compressor V3.
- a partial stream 3d of the refrigerant mixture of the second mixed refrigerant cycle 3a to 3e is withdrawn after the heat exchanger E1, relaxed in the valve c and then evaporated in the heat exchanger E1 against cooled process streams before this refrigerant mixture partial stream is fed via line 3e at an intermediate pressure level to the cycle compressor V3.
- the mentioned mixed refrigerant partial stream 3d contributes to the precooling of the hydrocarbon-rich stream in the heat exchanger E1.
- the partial flow 3d of the refrigerant mixture of the second mixed refrigerant cycle 3a to 3e used for the precooling of the hydrocarbon rich stream must be evaporated to a pressure higher than the evaporating pressure of the mixed refrigerant partial stream 3b of the second mixed refrigerant cycle 3a to 3e.
- the distribution of the cooling capacity of the second mixture cycle to the heat exchangers E1 and E2 and thus the precooling and liquefaction of the hydrocarbon-rich stream to be liquefied can be set almost arbitrarily.
- the inventive method for further liquefying a hydrocarbon-rich stream is proposed that the compressors V4 and V3 of the first and second refrigerant mixture cycle and the compressor V2 and V2 1 of the third refrigerant mixture cycle are driven by two substantially identical or power-driven drives.
- This embodiment of the method according to the invention is particularly advantageous if the total output of the compressors V2, V2 ', V3 and V4 can be provided by two sufficiently powerful drives. Plant availability is typically higher when the number of drives required to operate is minimized, which is the case if only two drives are used instead of four.
- the inventive method for liquefying a hydrocarbon-rich stream, in particular a natural gas stream thus enabling even more economical utilization of available compressors and drives than is possible in the known liquefaction processes.
- large, single-stream liquefaction plants with a liquefaction capacity greater than 5 million tonnes LNG per year benefit from the procedure according to the invention.
