Abstract

A method is described of liquefying a hydrocarbon-rich fraction 1, in particular natural gas, where the hydrocarbon-rich fraction which is to be liquefied is cooled and liquefied against a coolant mixture. The coolant mixture, before its cooling, is separated 'D' into a gas phase 5 and a liquid phase 6. The gas and the liquid phases are cooled 'E' separately, and not until after cooling has been performed, are they expanded 'a', 'b' and recombined 8. Preferably, the coolant mixture comprises the components nitrogen, methane, ethane, ethylene, propane, butane and/or pentane. Parts of the gaseous or liquefied hydrocarbon-rich fraction may be added to the coolant mixture to replace selected components, such as methane or nitrogen.

Description

Description
Method of liquefying a hydrocarbon-rich fraction The invention relates to a method of liquefying a hydrocarbon-rich fraction, in particular natural gas, wherein the hydrocarbon-rich fraction which is to be liquefied is merely cooled and liquefied against a coolant mixture, and the coolant mixture, before its cooling, is separated into a gas phase and a liquid phase.
Methods of the type in question for liquefying a hydro-carbon-rich fraction are used, in particular, in the implementation of natural gas liquefaction processes having a liquefaction power of 200 kW to greater than MW.
In Figure 1 a method of the type in question which is comparatively of little complexity in engineering for liquefying a hydrocarbon-rich fraction is shown.
The hydrocarbon-rich fraction which is to be liquefied is fed via line 1' to a heat exchanger E' and in this is cooled against a coolant mixture which is conducted via line 8' in countercurrent through the heat exchanger E' and liquefied. If necessary, a fraction of heavy hydrocarbons is separated off from the hydrocarbon-rich fraction which is to be liquefied in order to adjust the heating value of the liquefied hydrocarbon-rich fraction, in the case of natural gas liquefaction of the LNG, and/or to prevent these components from freezing out on further lowering of temperature. The liquefied hydrocarbon-rich fraction is subsequently fed via line 2' to its further use.
The coolant mixture which is completely vaporized in the cooling and liquefaction of the hydrocarbon-rich fraction is fed via line 3' to a compressor unit V1 which is designed as a single stage or multistage compressor unit and in this is compressed to the desired cycle pressure which is customarily in the range between 10 and 80 bar. Subsequently thereto the compressed coolant mixture is fed via line 4' to a separator D' and in this is separated into a gas phase and also a liquid phase.
The gas phase is taken off via the line 5' from the top of the separator D' and fed to the heat exchanger E'.
The liquid phase which is taken off from the bottom of the separator D' via line 6' is likewise fed upstream of the heat exchanger E' by means of the pump F' and mixed directly in the inlet to the heat exchanger E' with the gas phase which is fed via line 5'.
The gas and liquid phases which are mixed with one another are passed via line 7' through the heat exchanger E' and cooled. In the expansion valve a' a cold-producing expansion is then performed, before the expanded coolant mixture is again passed through the heat exchanger E' via the abovementioned line 8'.
This mixing of gas and liquid phases immediately before entry into the heat exchanger E' is thus useful since it enables the use of a structurally simple and thereby inexpensive heat exchanger. However, it is disadvantageous in this case that the mixing of the gas and liquid phases is comparatively complex, since at least one pump F' must be provided. Pumps in turn, however, are relatively high in costs and also maintenance.
It is an object of the present invention to specify a method of the type in question for liquefying a hydro-carbon-rich fraction, in particular natural gas, which avoids the abovementioned problems, and in particular, enables a cheaper and less maintenance-intensive liquefaction process to be implemented.
A method of liquefying a hydrocarbon-rich fraction, in particular natural gas, of the type in question is proposed for achieving this object, which method is characterized in that the gas and the liquid phases are cooled separately and not until after cooling has been performed are they expanded and recombined.
According to the invention the gas and also the liquid phases are then separately cooled to the desired temperature and not combined until subsequently, after expansion to the desired pressure. In this procedure according to the invention the use of a liquid pump can be omitted. The disadvantages associated with such a pump are therefore avoided. Instead of the pump, however, a further expansion valve is required.
The omission of the relatively fault-susceptible pump leads to higher operational reliability and also to longer running time of the liquefaction process. In addition, the operating personnel are relieved, since there is no monitoring of the pumps which were hitherto required. In addition, the method according to the invention leads to a saving of operating costs, in particular maintenance, power and personnel costs.
Further advantageous embodiments of the method according to the invention of liquefying a hydrocarbon-rich fraction, in particular natural gas, which are subjects of the dependent patent claims are characterized in that -the gas and liquid phases are recombined before or after warming thereof against the hydrocarbon-rich fraction which is to be liquefied, -a fraction which is rich in relatively heavy hydrocarbons is separated off from the hydrocarbon-rich fraction which is to be cooled, -the coolant mixture comprises the components nitrogen, methane, ethane, ethylene, propane, butane and/or pentane, -at least some of the hydrocarbon-rich fraction which is to be cooled, the fraction which is rich in relatively heavy hydrocarbons and has been separated off and/or the liquefied hydrocarbon-rich fraction is added to the coolant mixture, wherein these fractions preferably replace the component methane, -if the liquefied hydrocarbon-rich fraction is stored (temporarily) in a storage vessel, the return gas which arises in the storage vessel is at least in part added to the coolant mixture, wherein this return gas preferably replaces the component nitrogen and -if the coolant mixture is compressed in at least two stages, the liquid fraction(s) arising at the or an intermediate pressure after the cooling of the compressed coolant mixture is or are pumped to the final pressure of compression and fed to the separation of the coolant mixture.
The method according to the invention of liquefying a hydrocarbon-rich fraction, in particular natural gas, and also other embodiments of the same may be described in more detail hereinafter with reference to the exemplary embodiment shown in Figure 2.
As already described with reference to Figure 1, the hydrocarbon-rich fraction which is to be liquefied is fed via line 1 to a heat exchanger E and in this is cooled and liquefied against a mixed coolant stream -5-.
which is to be warmed and vaporized. *Via line 2, the liquefied hydrocarbon-rich fraction is subsequently taken off from the heat exchanger E. Via line 3, the coolant mixture which is taken off from the heat exchanger E is fed to a compressor unit V which is designed as a single stage or multistage compressor unit and in this is compressed to the desired final pressure. In correspondence to the selected design of the compressor unit V, liquid can arise at one or more intermediate stages after the cooling of the compressed coolant mixture, which liquid is pumped to the final pressure of the compressor unit V and is fed to the separator 0. The compressed coolant mixture is fed via line 4 to a separator D and in this is separated into a gas phase and also a liquid phase.
The gas fraction is taken off via line 5 from the top of the separator D and fed through the heat exchanger E for the purpose of cooling. At the cold end of the heat exchanger E there then proceeds a cold-producing expansion a of this fraction.
The liquid fraction which is taken off via line 6 from the bottom of the separator D is likewise cooled in the heat exchanger E and subsequently thereto is cold-producingly expanded in the valve b. According to the invention, the two fractions are then not combined until after the expansion has been performed in expansion valves a and b and are then jointly fed via line 8 through the heat exchanger E in countercurrent to the hydrocabon-rich fraction which is to be cooled and liquefied.
Alternatively to the procedure shown in Figure 2, the fractions which are passed through the heat exchanger E via lines 5 and 6 can also only be combined after their repeated passage through the heat exchanger E.
