- Methods for liquefying hydrocarbon-rich fractions or gas mixtures, in particular natural gas make use, inter alia, of closed refrigerant blend circuits in which the multicomponent refrigerant is at least partially condensed under elevated pressure at around ambient temperature and is vaporized at low pressure at below ambient temperature with a refrigerating action.
- closed refrigerant blend circuits in which the refrigerant fractions arising during compression are mixed before the indirect heat exchange with the hydrocarbon-rich fraction to be liquefied and jointly used in the heat exchanger.
- the hydrocarbon-rich fraction to be cooled and liquefied which is for example natural gas, is supplied via line 100 to the heat exchanger E 3 ′.
- the feed fraction is cooled against the refrigerant blend circuit which is yet to be described and supplied via line 101 to a separation unit T.
- This separation unit T which is simply shown as a black box, serves for example to separate nitrogen and/or higher hydrocarbons from the feed fraction 100 / 101 to be liquefied.
- the separation process performed in the separation unit T determines the temperature to which the feed fraction 100 / 101 must at least be cooled in the heat exchanger E 3 ′.
- the component(s) separated from the feed fraction is/are drawn off from the separation unit T via line 104 , while the remaining feed fraction to be liquefied is supplied again via line 102 to the heat exchanger E 3 ′ and is further cooled, liquefied and optionally supercooled therein.
- the feed fraction 103 treated in this manner is then sent for further use or to a storage tank.
- the refrigerant blend circuit required for cooling and liquefying the hydrocarbon-rich feed fraction 100 / 102 comprises an at least two-stage compressor unit C, a separator D 1 upstream of the compressor unit C and two separators D 2 and D 3 downstream of the compressor stages.
- Two post-coolers E 1 and E 2 which serve to dissipate the heat of compression and partially condense the refrigerant blend, and a pump or pump unit P are furthermore provided.
- the refrigerant blend vaporized in the heat exchanger E 3 ′ against the feed fraction 100 / 102 to be cooled and liquefied is supplied via line 1 to the above-stated separator D 1 .
- the gas phase drawn off from the top of this separator via line 1 ′ is supplied to the first compressor stage of the compressor unit C and compressed to a desired intermediate pressure.
- the compressed refrigerant blend is supplied via line 2 to the separator D 2 .
- a liquid phase which is rich in higher-boiling components of the refrigerant (HMR) is drawn off via line 3 from the bottom of the separator and pumped by means of the pump or pump unit P to the pressure of the gas phase which is yet to be described of the refrigerant blend.
- the gas phase drawn off via line 4 from the separator D 2 is supplied to the second stage of the compressor C and compressed to the desired final pressure of the refrigerant blend circuit. After passing through the post-cooler E 2 , the compressed refrigerant blend is supplied via line 5 to the separator D 3 .
- the liquid fraction 7 arising in the bottom of the separator D 3 is recirculated via the control valve V 1 before the input of the separator D 2 .
- a gas phase which is rich in lower-boiling components of the refrigerant blend (LMR) is drawn off at the top of the separator D 3 via line 6 and, after mixing with the above-described liquid phase 3 , is supplied via line 8 to the heat exchanger E 3 ′.
- the liquid phase 3 and the gas phase 6 are combined before the heat exchanger or immediately at the start of the heat exchange which proceeds in the heat exchanger E 3 ′ and supplied as a two-phase stream.
- the refrigerant blend is cooled in the heat exchanger E 3 ′ and completely liquefied.
- the refrigerant blend 9 is expanded with a refrigerating action in the valve V 2 and then completely vaporized on passing again through the heat exchanger E 3 ′.
- the available, fluctuating variables of the refrigerant blend circuit such as pressure profile, mass flow rate and composition, are used to control system capacity and the temperature of the feed fraction at the cold end of the heat exchanger E 3 ′ and to optimize energy consumption.
- the intermediate temperature in the heat exchanger E 3 ′ is not controllable independently of the load and temperature of the fraction to be liquefied at the cold end of the heat exchanger E 3 ′.
- An object of the present invention is to provide a method for liquefying a hydrocarbon-rich fraction, in particular natural gas, which makes it possible to achieve sufficiently accurate control of a further temperature in addition to the temperature at the cold end of the heat exchanger used for indirect heat exchange. This should be taken to mean control to at least 3° C., preferably to at least 1° C.
- the liquid phase and the gas phase of the refrigerant blend are in each case mixed in their entirety and jointly used for cooling and liquefying the feed fraction.
- indirect heat exchange between the hydrocarbon-rich fraction and the refrigerant blend now proceeds in at least two heat exchangers, wherein the first heat exchanger serves to precool and the second heat exchanger to cool and liquefy the hydrocarbon-rich fraction.
- the first or precooling heat exchanger is here predominantly cooled with the liquid phase of the refrigerant blend, while the second heat exchanger or liquefier is predominantly cooled with the gas phase of the refrigerant blend.
- the first heat exchanger is therefore supplied with a refrigerant blend which comprises 5 to 50% of the liquid phase which is rich in higher-boiling components (HMR) of the refrigerant blend.
- This liquid phase is mixed with the gas phase which is rich in lower-boiling components (LMR) of the refrigerant blend in such a way that an HMR/LMR mixing ratio of between 1.2 and 10 is established.
- the remaining proportions of the liquid phase and gas phase are used to cool the second heat exchanger.
- the refrigerant blend used for the first heat exchanger is now concentrated by a multiple in higher-boiling components and is accordingly higher-boiling.
- the refrigerant blend of the second heat exchanger is consequently concentrated in lower-boiling components of the refrigerant blend and accordingly lower-boiling.
- the refrigeration capacities and temperature profiles of the two heat exchangers may now be influenced via the mixtures and quantities of the respective refrigerant fractions in such a way that the temperature at the cold end of the first heat exchanger, and likewise the temperature at the cold end of the second heat exchanger, can be accurately controlled to at least 3° C., preferably to at least 1° C.
- FIG. 1 shows a prior art system for cooling and liquefying a hydrocarbon-rich fraction (discussed in detail above);
- FIG. 2 depicts an exemplary embodiment of the invention.
- the hydrocarbon-rich fraction 200 to be cooled and liquefied is now supplied to a first heat exchanger or precooler E 4 .
- the feed fraction is cooled against the refrigerant blend circuit which is yet to be described and supplied via line 201 to a separation unit T.
- the component(s) separated from the feed fraction is/are drawn off from the separation unit T via line 204 , while the remaining feed fraction to be liquefied is supplied again via line 202 to the second heat exchanger or liquefier E 3 and is further cooled, liquefied and optionally supercooled therein.
- the feed fraction 203 treated in this manner is then sent for further use or to a storage tank.
- the refrigerant blend circuit required for cooling and liquefying the hydrocarbon-rich feed fraction 200 / 202 corresponds to the refrigerant blend circuit explained with reference to FIG. 1 . Therefore only the differences relative to the refrigerant blend circuit explained with reference to FIG. 1 will now be addressed below.
- the liquid phase 3 drawn off from the bottom of the separator D 2 is distributed by means of the control valves V 6 and V 7 via the line portions 11 and 15 between the heat exchangers E 3 and E 4 .
- the heat exchanger E 4 is here supplied with a refrigerant blend which comprises 5 to 50%, preferably 10 to 30%, of the liquid phase which is rich in higher-boiling components (HMR) of the refrigerant blend.
- the distribution of the gas phase 6 which is drawn off at top of the separator D 3 and is rich in lower-boiling components (LMR) of the refrigerant blend via the line portions 10 and 14 between the heat exchangers E 3 and E 4 is determined by the mass balance of the combined refrigerant blend streams 12 and 16 via the valves V 2 and V 4 .
- LMR lower-boiling components
- Sub-streams of the gas phase 6 may be supplied via the line portions 13 and 17 to the refrigerant blend 12 or 16 respectively at the cold end of the first and/or the second heat exchanger E 4 or E 3 respectively.
- the control valves V 3 and V 5 provide a further possibility for temperature control at the cold end of the heat exchangers E 3 and E 4 .
