Definitions
- the present invention relates first of all to a process for producing impure helium from a feed gas mixture containing helium and other heavier components, of the type in which:
- the invention applies for example to the production of helium from a waste gas from a natural gas liquefier, this waste gas containing, in addition to helium, methane and nitrogen.
- the invention aims to meet this need in a particularly effective way.
- the invention relates to a process of the aforementioned type, characterized in that, in addition, at least one of said components in the form of a liquid product by implementing a closed refrigerating cycle with variable flow rate, the flow rate of which is a function of the flow rate of said liquid product.
- This process can include one or more of the following characteristics:
- the refrigeration cycle is a nitrogen cycle
- the liquid phase obtained by the second partial condensation is enriched with one of said components, and the resulting fluid is recovered as a second product;
- distillation pressure is substantially equal to the pressure for producing impure helium.
- the invention also relates to a unit for implementing the method defined above.
- This unit of the type comprising:
- a heat exchanger adapted to cool and partially condense the vapor phase coming from the condenser passages of the head condenser, - a phase separator connected to the cold end of the heat exchanger,
- a process for producing pure helium characterized in that a process for producing impure helium as defined above is implemented, and impure helium and said liquid product are sent a unit for purifying, and optionally liquefying, helium comprising a cryogenic part; and - on the other hand, an installation for producing pure helium, characterized in that it comprises a unit for producing impure helium as defined above, and a unit for purifying, and optionally liquefying, helium comprising a cryogenic part, this unit being supplied by the impure helium produced by the unit and by said liquid product.
- the installation shown in the drawing comprises a unit A for the production of impure helium, and a unit B for the purification of impure helium.
- This unit B has a cryogenic part, which can be a cryogenic helium purification device and / or a device for liquefying pure helium.
- Unit A essentially comprises a two-stage supply compressor 1, a heat exchange line 2, a distillation column 3 provided with a head condenser 4, a heat exchanger 5, two phase separators 6 and 1, and a closed refrigeration cycle 8 with nitrogen.
- Unit A produces impure helium at 25 bars (line 9), gaseous nitrogen at 7 bars (line 10), liquid nitrogen at 8 bars (line 11), a first waste l rich in methane (line 12), a second methane-rich waste W2 (line 13), 'and a waste nitrogen-rich W3 (line 14). All the cold parts of this unit A are contained in the same cold box 15 suitably thermally insulated.
- a low pressure feed mixture at 3.9 bars, brought through a line 16 is compressed to 8 bars by the first stage of the compressor 1, then it is compressed to 26 bars, that is to say slightly above the pressure producing impure helium, together with a high pressure feed mixture passed in line '17.
- the compressed mixture is cooled and partially condensed in the exchange line 2 and is introduced into the tank of the column 3.
- the tank liquid of this column is expanded in an expansion valve 18 to around 4 bars and introduced into the calender 19 condenser 4 to refrigerate it.
- This refrigeration causes in the condenser 4 the partial condensation of the top gas of the column.
- the non-condensed fraction is an intermediate gas containing approximately 25% helium and 75% nitrogen, and traces of methane. This intermediate gas is cooled and partially condensed in the exchanger 5, then separated into two phases in the separator 6.
- the vapor from this separator contains about 70% helium. After heating in 5 and 2, this vapor constitutes the impure helium produced by unit A, recovered after heating in 5 and then in 2, via line 9. This gas will then be treated in unit B for the purification, and possibly liquefaction, of helium.
- the gas rich in methane which results from the vaporization in the calender 19, still containing helium, is reheated in 2. A majority of this gas is recycled via a line 20 to the suction of the first stage of the compressor 1, and the remainder is discharged via line 12 as a methane-rich waste Wl.
- a flow of the liquid contained in the calender 19 is withdrawn by a pump 21, vaporized and heated in the exchange line 2 then constitutes the other residual W2 rich in methane, which is evacuated via line 13.
- the two Methane-rich fluxes can be valued, in particular for their calorific value.
- the liquid phase of separator 6 contains approximately 99% nitrogen. After expansion to 8 bars in an expansion valve 22, this liquid is introduced into the separator 7.
- the liquid phase constitutes a production of liquid nitrogen from unit A, conveyed via line 11, while the gas phase constitutes a waste W3 rich in nitrogen, at around 95% nitrogen, which is evacuated via line 14.
- part of the liquid nitrogen is vaporized in exchanger 5 to cool it, then, after reheating in 2, forms the flow of production nitrogen gas recovered via line 10.
- the nitrogen refrigeration cycle 8 is a closed cycle with variable flow independent of the rest of the installation. It comprises a cycle compressor 23 and a turbine 24-booster assembly 25 coupled to one another.
- the cycle nitrogen compressed in 23 to 15 bars and boosted in 25 to 23 bars, is cooled in the line exchange 2 up to an intermediate temperature level and relaxed in 24 to 1.6 bar.
- the nitrogen thus cooled is used to cool the exchanger 5, then continues to heat up in 2 and returns to the suction of the compressor 23.
- the refrigeration cycle is only necessary when liquid nitrogen is produced, and the cycle nitrogen flow is adjusted according to the liquid nitrogen flow produced.
- This liquid nitrogen is at least partly sent via line 11 to the purification / liquefaction unit B, and optionally partially exited from the installation via a production line 26 tapped on line 11.
- Unit B supplied with impure helium through line 9 and liquid nitrogen through line 11, produces pure helium, possibly liquid, via line 27, and a residual gas W4 via line 28.
- liquid nitrogen is integrated into unit A and in particular in the cold box 15 thereof.
