Use the dewater unit of the method recommend can be for for extract a part for the recombiner unit of carbon dioxide from gas.
In some cases, in order to reduce costs and operating cost, cyclone separator or vortex tube can be installed and to replace turbine expander.In these cases, in the process expanding at gas, can obtain lower pressure in the passage of cyclone separator or vortex tube, and can allow gas reach lower temperature, therefore improve the efficiency of gas dewatering process.
Fig. 4 has shown another the possible example having for the cyclone separator of gas expansion or the apparatus and method of vortex tube according to of the present invention.Position 20 represents cyclone separator or vortex tube.
In some cases, cannot in cyclone separator or vortex tube, gas arteries and veins stream be separated from liquid qualitatively.Therefore, from the two-phase arteries and veins stream 21 of cyclone separator or vortex tube, be directed to separator 9, at this, liquid 10 is separated and be directed to unstripped gas and mix, as shown in Figure 5.That is to say, in this embodiment, carried out the compound expansion of gas.
In order to control the parameter in dehydration in a big way, can within least two stages, carry out gas expansion.In the stage therein, expansion is carried out in cyclone separator and/or choke valve.
Fig. 6 has shown a variant embodiment that realizes two-stage gas expansion of the present invention.At this, the two-phase arteries and veins stream flowing out from cyclone separator or vortex tube is directed to extra separator, at this, occurred the separated of liquid and with the mixing of unstripped gas.In this variant embodiment, first gas expands in turbine expander 13, then in the passage of cyclone separator or vortex tube 20, carries out.
In Fig. 7, show method and apparatus, wherein, the biphase mixture obtaining after expanding is separated from dry gas.In extra separator, liquid is separated from two-phase arteries and veins stream.Compressed, cooling from the gas in this extra separator, then mix with unstripped gas.That is to say, the biphase mixture obtaining after expanding is separated from dry gas and two-phase arteries and veins stream, in described extra separator, liquid is extracted away from two-phase arteries and veins stream.Fig. 7 has shown the example of realizing this situation.
After gas expands in turbine expander 13, gas carries out extra expansion in the passage of vortex tube (or cyclone separator) 20.At gas, import vortex tube (such as cyclone separator) before, can be from gas separating and condensing thing 29.Two-phase from vortex tube is directed in extra separator 9, be directed in unstripped gas, and gas is further compressed in compressor 14 from the liquid in this extra separator, is cooled, and mixes with unstripped gas in air-cooling apparatus 18.
Cold by force for gas is carried out, and the dew point of the water of the gas that therefore reduction is discharged, can carry out cooling to unstripped gas and/or the mixture forming after unstripped gas is mixed with the liquid of the water that comprises dissolved form.
Fig. 8 has shown and has realized a this cooling example.At this, to the unstripped gas forming after unstripped gas is mixed with the liquid of the water that comprises dissolved form, carry out cooling.That is to say, the unstripped gas in given embodiment continues cooling in air-cooling apparatus 18 and in recuperative heat exchanger.
In all embodiment of the method according to this invention, before the expansion that realizes unstripped gas, the liquid that comprises Free water can be added in unstripped gas, wherein, liquid can be by additionally cooling.
Table 1 has below been shown the operation of the inventive method and the result obtaining, the result especially obtaining by the device shown in Fig. 2.
