Definitions
- the invention provides a method for removing contaminating gaseous components, such as carbon dioxide (CO2) and hydrogen sulphide (H2S) , from a natural gas stream.
- contaminating gaseous components such as carbon dioxide (CO2) and hydrogen sulphide (H2S)
- Various processes are known to remove contaminating gaseous components from a natural gas stream.
- the processes may be based on physical and/or chemical separation techniques.
- the physical separation techniques use differences in boiling, condensation and/or freezing points of the various contaminating components to selectively remove one or more of these components in a fractionating column, or differences in density to separate components with different densities in a centrifugal or cyclonic separator.
- the chemical techniques may employ selective absorption or catalytic reactions to convert a contaminating component into a composition that can be easily separated.
- the standard technique for removing hydrogen sulphide and carbon dioxide from natural gas is amine treatment, which is based on solvent absorption. In this process the contaminating components are bound on a molecule such as diethanol amine in an aqueous solution.
- the clean hydrocarbon gas is not absorbed and emerges in the product gas stream.
- the solution with the absorbed contaminant is recycled and heated by approximately 100 0 C to drive off the gases, which then are collected in a waste stream.
- the major cost factors in this process are the energy requirement for waste gas regeneration, solvent losses and the fact that the waste gases are regenerated at near atmospheric pressure - any process such as reinjection requires compression.
- Known gas separation centrifuges rotate at about 50,000 revolutions per minute (RPM) to separate gaseous fractions with only minor differences in density. These fast rotating centrifuges are known as ultracentrifuges and have limited separation efficiency and can only handle a limited flux of gas. If a large natural gas stream containing a large fraction of contaminants is to be purified by means of centrifuges then a large amount of centrifuges or ultracentrifuges are required, which renders centrifugal separation uneconomical.
- RPM revolutions per minute
- the method according to the invention for removing contaminating gaseous components, such as CO2 and/or H2S, from a contaminated natural gas stream comprises:
- centrifugal separator which comprises a bundle of parallel channels that are arranged within a spinning tube parallel to an axis of rotation of the spinning tube .
- the contaminants depleted gas stream is recompressed in a compressor.
- the expander is a turbine expander and the compressor is a turbine compressor
- the turbine expander and the turbine compressor may comprise rotors that are mounted on a common shaft.
- Figure 1 illustrates a cooling and separation assembly comprising two channelled centrifugal separators in series for use in the method according to the invention.
- Figure 2 illustrates at a larger scale one of the channelled centrifugal separators of Figure 1.
- Figures 2A-2D illustrate various shapes of the channels in the separator of Figure 2.
- the invention relates to the use of one or more channelled centrifugal separators 2,3 for the separation of contaminating gaseous components, such as CO2 and/or
- H2S from a natural gas stream, that comprises methane (CH4), ethane, propane, butane and/or condensates, in an efficient manner even if a large natural gas stream with a large fraction of contaminants (25-75% by weight) is to be purified.
- CH4 methane
- ethane propane
- butane butane
- Figure 1 illustrates that in accordance with the invention the contaminated natural gas stream is cooled in a turbine expander 1 to obtain an expanded gas stream having a temperature and pressure at which the dewpointing conditions of the phases containing a preponderance of contaminating components, such as CO2 and/or H2S, are achieved.
- a turbine expander any other type of expander may be used to expand the contaminated natural gas stream, for example a converging-diverging nozzle, a valve, an orifice or a porous plug.
- the expanded gas stream from expander 1 is supplied to segmented centrifugal separator 2.
- the residence time of the expanded gas stream between the outlet of expander 1 and the inlet of separator 2 is such that at least part of the contaminants will liquefy by a combination of nucleation and coagulation.
- a dispersion of a contaminants-enriched liquid phase in a contaminants- depleted gaseous phase is formed upstream of centrifugal separator 2.
- the residence time between expander and centrifugal separator is in the range of from 0.5 to 5 seconds, in order to allow for sufficient nucleation of the contaminants-enriched phase followed by sufficient coagulation of droplets to form droplets with a diameter in the micrometer range.
- the formation of the dispersion suitably takes place in an insulated conduit connecting expander 1 with centrifugal separator 2.
- centrifugal separator 2 At least part of the contaminants-enriched liquid phase is separated from the contaminants-depleted gaseous phase.
- a purified natural gas stream (CH4) and a liquefied contaminants stream (CO2 and/or H2S) are obtained.
- further contaminants are removed from the purified natural gas stream in a second segmented centrifugal separator 3.
- each segmented centrifugal separator 2,3 comprises a spinning tube 4,5.
- the tubes 4,5 are mounted on a common shaft 6 that rotates about a central axis of rotation 7.
- Each centrifugal separator 2,3 comprises an outer liquefied contaminants outlet 8,9 and a central purified natural gas outlet 10,11.
- the outlets may be arranged near the downstream end and/or near the upstream end of each spinning tube 4,5. In the embodiment of Figure 1, the outlets are near the downstream end of each spinning tube 4,5.
- the central purified natural gas outlet 10 of the first centrifugal separator 2 feeds a stream of partially purified natural gas with a reduced CO2 and/or H2S content via a recompression turbine 12, optionally an interstage cooler (not shown) , and a turbine expander 14 into the inlet of the second centrifugal separator 3.
- Figure 1 also shows that a recompression turbine 15 and a cooler 16 are connected to the central purified natural gas outlet 11 of the second centrifugal separator 3 and that the expansion and recompression turbines 1, 12, 14 and 15 are mounted on a common shaft 17.
- the shaft 6 and tubes 4 and 5 of the first and second centrifugal separators 2 and 3 rotate about the central axis of rotation 7, typically at a rotation speed in the range of from 500 to 5,000 revolutions per minute (RPM) , preferably of from 500 to 1,500 RPM. This speed is typically less than 10% of the speed of an ultracentrifuge.
- An electrical or other motor may rotate the shaft 6.
- the gas stream fed into the centrifugal separators 2 and 3 may be induced to swirl by one or more swirl imparting vanes, such that the swirling gas that enters the centrifugal separators 2 and 3 induces the separators 2 and 3 to rotate about the central axis of rotation 7 at the desired speed of rotation of in the range of from 500 to 5,000 RPM.
- FIGS 2 and 2A-2D illustrate in more detail the construction of the first centrifugal separator 2, which is identical to the construction of the second centrifugal separator 3.
- FIG 2 shows schematically that an annular space 18 is present between central shaft 6 and the inner surface of the spinning tube 4.
- This annular space 18 is filled with an assembly of substantially axial flow channels 19 that may have various shapes that are shown in more detail in Figures 2A-2D.
- Figures 2A-2D show at an enlarged scale the shaded segment A-D of Figure 2 and illustrate that the flow channels 19A-19D may have a tubular, rectangular or corrugated shape and are arranged substantially co-axial to the axis of rotation 7 of the tube 4.
- the flow channels 19A-19D effectively decouple the axial turbulence associated with high throughput from the preserved radial laminarity.
- the width in radial direction of the channels 19A-19D is typically between 0.5 and 5 mm depending on flow conditions.
- the condensed nucleated waste is typically in the range 5-50% of the volume of the channels 19A-19D and is directed by the centrifugal force to the outer channel walls where a slower flowing film forms which can be collected radially from the downstream and the upstream end of the spinning tube 4 via the liquefied contaminants outlet 8 while the at least partly purified natural gas stream CH4 is discharged via the central gas outlet 10 of the centrifugal separator 1 shown in Figure 1.
- the purified CH4 ⁇ enriched natural gas stream discharged via the central purified natural gas outlet 10 is further separated in the second centrifugal separator 3 in the manner as described with reference to Figure 1.
- the purified natural gas stream discharged via the central outlet 11 of the second centrifugal separator 3 may be further treated (not shown) in a small scale amine treater, a selective absorption system, or a membrane separation system with associated additional deep cut purification processes to make the purified natural gas stream suitable for distribution or liquefaction in a LNG plant.
- a third and optionally a fourth centrifugal separator (not shown) to purify the natural gas stream such that it has a sufficiently low CO2 and/or H2S content.
- the condensed CO2 and/or H2S streams discharged via the outer outlets 8 and 9 of the centrifugal separators 2 and 3 are collected and then heated (optionally by integration of the heater with the cooler 16) so that a re-pressurized waste gas stream with a large content of re-evaporated CO2 and/or H2S is available for re-injection into a subsurface formation, such as the gas bearing reservoir formation, thus saving on compressor requirements.
- the liquefied contaminants in the channels 19A-19D may contain a small fraction of natural gas (CH4).
- CH4 natural gas
- some CO2 necessarily ends up in the purified natural gas stream in the central outlet 11.
- the estimated energy costs of cleaning contaminated gas containing in the range of from 25 to 75% by weight of CO2 and/or H2S by amine technology are prohibitive, ranging from 45%-200% of the produced clean gas value, whereas the estimated energy costs of the centrifugal separator assembly according to the invention are more than an order of magnitude below this at 0.5%-2% of the produced clean gas value.
- H2S has a lower dewpoint pressure than CO2, H2S can be separated easier with the centrifugal separator assembly according to the present invention than CO2 from a contaminated natural gas stream.
- the method according to the present invention is much more energy efficient than conventional amine treatment separation techniques and ultracentrifuge separation techniques in which gaseous phases with different densities are separated from each other .
- the method according to the invention may also be used to remove other contaminants than CO2 and H2S from a natural gas stream.
- Such other contaminants may be water, solids, such as dust and sandy particles, and hydrocarbons other than methane, for example ethane, propane and butane. Examples
- the centrifugal separator was mounted vertically in a sealed housing.
- the height was 262 mm and the diameter 130 mm.
- the rotating element was machined from an integral cylinder of Duplex steel of length 250 mm and diameter 83 mm. For this relatively low gas throughput, a single annulus of channels on the rotating element was sufficient. However, for higher throughputs, the entire radial range of the rotating element is larger and will be completely used with a construction based on successive wrappings of corrugated thin layers of steel so that, when wound around an axis, a channelled filter- like structure results with dimensions similar to those described in this example.
- a number of slotted channels were milled each of 2 mm height and 2 mm width with a centre-to-centre spacing of 5 mm.
- a hollow cylinder of similar material was machined to form a sleeve having the same axial length but an inner diameter of 83 mm and an outer diameter of 85 mm.
- This hollow cylinder was shrink-wrapped around the slotted cylinder by the following procedure: the channeled material was cooled to 243 K and the sleeve heated to 573 K. The latter was then placed over the former and the two were quenched in a water bath at room temperature .
- the gas stream containing droplets of a liquid carbon dioxide-rich contaminant phase that was formed in the insulated conduit was fed via a radial entry to the inlet of the housing and entered the separator which was rotated by use of a magnetic coupling system driven by an electric motor.
- the rotation rate was 500 RPM.
- a liquid carbon dioxide-rich contaminant phase was formed on the walls.
- the droplets so generated were at least one order of magnitude larger than those in the inlet gas and were centrifugally spun out to exit channels on the walls where the collected liquid was discharged from the centrifuge to a waste collection vessel. Ingress of the gas was prevented by the use of liquid level seals on the outlets at the downstream and the upstream end of the rotating element.
- a waste stream of 34 kg/hr comprising 90 wt% carbon dioxide and 10 wt% methane and a purified natural gas stream of 46 kg/hr comprising 67 wt% methane and 33 wt% carbon dioxide were recovered from the centrifugal separator.
- the recovery of methane was 95 wt, based on the amount of methane in the input stream of natural gas
