Definitions

  • This invention relates to apparatus for, and a method of, separating a mixture of hydrocarbon liquid and aqueous liquid into discrete hydrocarbon liquid, and aqueous liquid phases.
  • the invention is primarily concerned with the three phase separation of a production flow from an oil well, and although strictly speaking the mixed phases within such a production flow are gas, hydrocarbon liquid, and aqueous liquid, it is conventional in the industry to refer to the phases as gas, oil and water. It must also be recognised that there are oil wells which have a production flow free, or substantially free, of gas, either because no gas is present or because gas is removed as a first operation, and thus the invention disclosed herein encompasses the processing of gas free oil and water mixtures.
  • a separation apparatus comprising a gravity separator vessel having, an inlet through which mixture to be separated enters the vessel, water and oil outlets spaced from the inlet of the vessel so as to afford a predetermined residence time within the vessel, a further liquid outlet from the vessel, and a further separator receiving liquid from the gravity separation vessel by way of said further liquid outlet, said further separator separating said liquid into oil rich and water rich flows.
  • said further separator is a centrifugal separator.
  • said furthor separator is a hydrocy clone.
  • the apparatus further includes a monitoring and control arrangement for controlling the flow rate of liquid to said further separator in accordance with the nature of the liquid flowing to the further separator.
  • said monitoring and control arrangement is responsive to whether said liquid is an oil continuous mixture or a water continuous mixture.
  • said monitoring and control arrangement is responsive to the oil/ water ratio of said liquid.
  • said monitoring and control arrangement includes a watercut meter.
  • each of said first and second further liquid outlets has its own monitoring and control arrangement for controlling the flow rate of liquid extracted by way of that outlet.
  • the invention nirther resides in a method of separating an oil and water mixture comprising the steps of supplying the mixture into the vessel of a gravity separator, the vessel having an inlet through which mixture to be separated enters the vessel, water and oil outlets spaced from the inlet of the vessel so as to afford a predetermined residence time within the vessel, and a further liquid outlet from the vessel, and supplying liquid from said vessel by way of said further liquid outlet to a further separator which separates said liquid into oil rich and water rich flows.
  • the method includes the further step of extracting further liquid from the vessel by way of a second further outlet.
  • said liquid extracted by way of said second further outlet is processed in a second further separator.
  • liquid extracted by way of said second further outlet is mixed with the liquid extracted by way of the first mentioned further outlet for processing by the further separator.
  • Figure 1 is a diagrammatic representation of a basic separation apparatus in accordance with a first example of the present invention.
  • Figures 2, 3, 4, 5 and 6 are, respectively, diagrammatic representations of separation apparatus in accordance with second, third, fourth fifth and sixth examples respectively of the present invention.
  • the separation apparatus includes a generally conventional three phase gravity separator 11 including a horizontally elongate separation vessel 12.
  • the vessel 12 has an inlet assembly 13 at one end thereof by way of which a production flow comprising a mixture of hydrocarbon gas, hydrocarbon liquid and aqueous liquid (conventionally referred to as gas, oil and water) enters the vessel 12.
  • a production flow comprising a mixture of hydrocarbon gas, hydrocarbon liquid and aqueous liquid (conventionally referred to as gas, oil and water) enters the vessel 12.
  • the inlet assembly 13 of the gravity separator 11 includes a gas/liquid cyclone separator 14 through which the whole of the inlet flow passes.
  • the cyclone separator 14 separates the inlet flow into a gas phase and a liquid phase, and discharges the gas phase into a head space 15 of the vessel 12.
  • the head space 15 has an outlet 16 by way of which separated gas can flow from the vessel 12 for collection and/or further processing.
  • the liquid phase discharged from the underflow outlet of the separator 14 occupies the volume of the vessel 12 below the head space 15 and immediately commences to separate under gravity into an oil phase floating on a water phase.
  • there is an intermediate phase comprising an oil/water dispersion the depth of which diminishes with distance from the inlet assembly 13 in accordance with the residence time of the liquid in the vessel 12. It will be understood that the majority of the gas in the inlet mixture is separated therefrom by the separator 14, although further dissolved gas may be evolved from the liquid phase while it remains resident in the vessel, this further evolved gas collecting in the head space.
  • a perforated plate 17 is positioned within the vessel 12 adjacent the inlet assembly 13, 14 and divides at least the liquid containing part of the vessel 12 into an inlet section and a settling section, the plate 17 serving to minimise the effect on the liquid in the settling section of any turbulence which may arise in the region of the inlet assembly.
  • Adjacent its end remote from the inlet the vessel 12 has a vertically extending weir plate 18 occupying the full width of the vessel and extending upwardly from the base of the vessel to a height in excess of the maximum intended height of the top of the water and oil / water dispersion layers in that end region of the vessel.
  • the oil layer in use overflows the weir plate 18 so that the far end region of the vessel 12, downstream of the weir plate, defines an oil outlet region 19 communicating with an oil outlet line 21 containing a control valve 21a.
  • the oil flow from the vessel 12 by way of the line 21 is controlled by the valve 21a, and, as will be understood by experts in the art, the oil in the line 21 may still contain a small proportion of water, and dependent upon the quantity of retained water in the oil in the line 21 the oil may be classed as "export quality" in which case it may be transported from the production site for further processing elsewhere, or alternatively may be subject to a further water removal process, for example in a coalescer before being classed as "export quality". It follows therefore that the final destination of the line 21 will be determined by the quality of the oil in the line 21, but this is not of significance to the present invention.
  • the vessel 12 Upstream of the weir plate 18, that is to say on the side of the weir plate presented to the inlet assembly 13, 14, the vessel 12 has a water outiet line 22.
  • the water outlet line communicates with a low point in the vessel 12 adjacent the weir plate 18, so that the water extracted through the outlet line 22 is the purest water stratum within the vessel.
  • the water extracted from the line 22 will still contain some oil and so may require further processing to minimise its oil content before the produced water can be discharged into the environment.
  • the form of the vessel 12 and the construction of its oil outlet arrangement may vary widely from that shown in Figure 1.
  • the oil outlet arrangement could incorporate a known "bucket and pipe” weir arrangement rather than the weir plate 18 illustrated
  • the arrangement shown in Figure 1 differs from known arrangements in that its processing capacity is augmented by the addition of a liquid extraction line 26 through which part of the liquid phase in the vessel 12 is extracted for parallel processing.
  • the liquid phase in the vessel 12 will have been substantially degassed as it enters vessel 12, either externally or by an arrangement such as the gas/liquid cyclone 14.
  • the liquid phase extracted through the line 26 is a degassed liquid and so is suitable for further separation into the individual liquid phases by means of one or more hydrocyclones.
  • the line 26 is connected through a watercut meter 27 to the inlet of a pre- deoiler hydrocyclone 28 which separates the mixture flowing into it from the line 26 into an oil rich phase flowing from the overflow outlet of the hydrocyclone 28 into a line 29, and a water rich phase leaving the underflow of the hydrocyclone 28 into a line 31.
  • the line 26 communicates with the vessel 12 upstream of the perforated baffle plate 17 and so is closely proximate the discharge of the separator 14. Furthermore, the line 26 opens into the interior of the vessel close to the low point thereof so as to take liquid which has undergone partial separation, and so is a water continuous, oil / water mixture.
  • Control valves 29a, 31a are positioned in the lines 29, 31 respectively, and as mentioned previously, the ultimate destination of the various output lines is not of significance to the present invention.
  • the watercut meter 27 is preferably a microwave meter which can output a control signal representative of the oil-to-water ratio of the liquid mixture in the line 26 and this control signal can be used to control the settings of the valve 31a to control the rate of flow of liquid through the hydrocyclone 28, and thus the rate at which liquid is being extracted from the vessel 12 through the line 26.
  • the valve 31a is adjusted towards its closed condition to reduce the flow through the line 26. Conversely when the meter detects that the watercut of the mixture is too high the valve will be opened to increase the flow through line 26.
  • the nature of the oil/water mixture is such that its oil/water inversion point (the point at which the mixture becomes water continuous) occurs at a watercut of 70%, and thus 70% watercut would be an ideal setting for the meter 27.
  • a setting in the range 75% - 85%, conveniently 80% is selected so that the valve 31a_is caused to open should the meter 27 detect that the watercut of the liquid in the line 26 exceeds 80% , and the valve 31a is caused to close when the detected watercut falls below 80%.
  • the signal from the meter 27 is used in conjunction with differential pressure monitors sensing respectively the pressure differential Dpi between the input of the cyclone 28 and its overflow output into the line 29, and the pressure differential Dp2 between the input of the cyclone 28 and its underflow output into the line 31.
  • PDR measured pressure ratio
  • F the flow split F across the hydrocyclone
  • the required PDR giving this split ratio of 20% is known from experimental data and valve 29a is then regulated to achieve this PDR value.
  • the PDR ratio would then be fixed as for a de-oiling cyclone regulating routine.
  • the line 26 is positioned to receive a water continuous mixture resulting from partial separation of the inlet mixture in the inlet zone of the vessel 12.
  • the line 26 could be positioned to receive an oil continuous mixture with the hydrocyclone processing of the flow along the line 26 being arranged in a number of hydrocyclone stages to de-water oil continuous flows.
  • the gravity separation may be augmented by extraction of both water continuous and oil continuous phases separately from the vessel 12. Where a hydrocyclone processes an oil continuous phase extracted from the vessel 12 the oil rich overflow of the hydrocyclone may be pumped back into the vessel 12 while the underflow is routed for further processing before the water is discharged.
  • the overflow can be fed, without the need to pump, into the oil layer in a downstream vessel.
  • the underflow can be fed to a pre- deoiler or deoiler hydrocyclone, or to the water layer of a downstream vessel dependent upon its oil/water ratio.
  • the perforated baffle plate 17 is omitted, and thus there is not a readily defined inlet zone with which the line 26 communicates.
  • the line 26 takes liquid from the vessel 12 proximate the inlet, but advantages can be obtained by extracting liquid phase anywhere along the vessel upstream of the weir plate 18 or its equivalent, but desirably between the inlet assembly and midway between the inlet assembly and the weir plate 18.
  • the positioning both longitudinally of the vessel, and vertically within the vessel, of the intake end of the line 26 will be determined by experience in relation to the geometric configuration of the vessel 12 itself, and the constituents of the production flow entering the inlet 13 and their gravity separation characteristics.
  • the intake end of the line 26 can be vertical or horizontal and can be located in any of the water, oil, and oil/water dispersion zones.
  • inlet assembly 13, 14 can be utilized in a gravity separator. It is, for example, not essential that the inlet assembly includes a gas/liquid separator in the form of a cyclone separator.
  • a well known form of gravity separation vessel has an inlet assembly in which a nozzle directs the inlet flow onto a splash plate which deflects the flow downwardly into one end region of the vessel. The effect of the splash plate is to promote evolution of gas from solution, and so acts to de-gas the inlet flow.
  • the turbulence generated by the splash plate also can emulsify the oil and liquid mixture rendering it more difficult to separate under gravity. Nevertheless it is to be understood that the invention can be utilized in relation to gravity separators having splash plate type inlet assemblies or other types of inlet distributor.
  • the assembly of Figure 2 represents a convenient separation system.
  • the line 22 feeds the inlet of a deoiler hydrocyclone 23.
  • the hydrocyclone 23 has an overflow outlet and an underflow outlet, the overflow outlet communicating with a line 24 through a control valve 24a and the underflow outlet communicating with a line 25 through a control valve 25a.
  • the function of the deoiler hydrocyclone 23 is to separate substantially the whole of the oil content of its inlet flow and thus the liquid flow from the underflow outlet of the hydrocyclone 23 into the line 25 is clean water, the purity of which is such that it is suitable for discharge into the environment if so desired.
  • the line 31 carrying the underflow of the hydrocyclone 28 supplies the inlet of a deoiler hydrocyclone 32.
  • the output of the deoiler hydrocyclone 32 is similar to the output of the deoiler cyclone 23, the oil leaving the hydrocyclone 32 by way of the overflow outlet and a line 33 as an oil and water mixture, and the clean water leaving the underflow outlet of the hydrocyclone 32 by way of a line 34.
  • the lines 33 and 34 contain control valves 33a, 34a and the line 33 communicates with the overflow line 24 of the hydrocyclone 23 while the line 34 communicates with the underflow line
  • valve in the line 31 is omitted, its control function under the action of the meter 27, being performed by the valve 34a_
  • control valves in the output lines of the hydrocyclones 23, 32, and in the line 21 will be controlled in known manner in accordance with other parameters of the system, such for example as fluid levels in the vessel 12, to achieve given operating characteristics of the system. It is however within the ambit of the present invention to provide a control system which provides control signals for all of the control valves, or to have all of the valves manually controlled in accordance with analysis in use of the liquid mixtures in the various output lines.
  • Figures 1 and 2 illustrate the line 26 extending through the lower wall region of the vessel 12 at the inlet end of the vessel. It is to be understood however that there will be occasions in which it is desirable to retrofit the line 26 and its associated equipment to an existing gravity separator vessel 12.
  • the line 26 may be desirable for the line 26 to penetrate the wall adjacent the lines 21, 22 in which case the line 26 will extend within the vessel 12 to the point at which it is desired to extract liquid from the vessel.
  • the line 26 extends into the vessel 12 through the union defining the line 22, the line 26 extending physically, coaxially within the line 22 through a common union into the interior of the vessel 12.
  • the line 26 extends axially to the point at which it is desired to extract liquid whereas of course the line 22 extracts water from a point adjacent the weir plate 18.
  • the line 26 is led through the wall of the line 22 so that the line 22 feeds the hydrocyclone 23 while the line 26 feeds the hydrocyclone 28 through the intermediary of the watercut meter 27.
  • FIG 3 illustrates an embodiment of the invention in which the vessel 12 has an inlet assembly 13, 14 disposed midway along the length of the vessel 12 with the liquid discharged from the inlet assembly 13, 14 flowing outwardly in opposite directions to duplicated oil and water outlet lines 21, 22 at opposite ends respectively of the vessel.
  • the gravity separator system of Figure 3 is a pair of gravity separators of the kind shown in Figure 1 positioned back-to-back and sharing a common inlet assembly 13, 14.
  • Figure 4 illustrates an adaptation of the gravity separator construction of Figure 3 in which the vessel 12 is divided horizontally into upper and lower chambers which communicate with one another at opposite axial ends of the vessel. Parts common the arrangement in Figure 3 carry the same reference numerals, and it can be seen that the horizontal dividing wall 36 has a centrally disposed well 37 into which the inlet assembly extends. The line 26 extends upwardly through the bottom wall of the vessel 12 and through the dividing wall 36 to extract liquid from the lower region of the well 37 beneath the inlet assembly 13, 14.
  • the dividing wall 36 in effect extends the flow path of liquid between the inlet and outlets, liquid flowing outwardly above the wall from the inlet assembly 14 towards the opposite axial ends of the vessel, and then subsequently flowing beneath the wall 36 inwardly from the axial ends towards the central region.
  • the two weir plates 18 are positioned adjacent the central section of the vessel 12 and the vessel can therefore have a single oil outlet line 22 disposed beneath the well 37 of the plate 36.
  • Variants described above in relation to Figures 1 and 2 can generally be utilised in the embodiments illustrated in Figures 3 and 4.
  • an additional line 26a can be provided so that there are two (or more) extraction lines. It is suggested that the additional line or lines 26a supply respective hydrocyclones, but in a modification ( Figure 5) the flow in the lines 26, 26a is mixed for supply to a single hydrocylone or chain of hydrocylones.
  • Each line 26, 26a could be provided with a respective watercut meter 27 or the like and an associated control valve arrangement 27a for controlling the flow in the respective line 26 in relation to the composition of that flow as described above.
  • the lines 26, 26a will extract liquid from different regions of the vessel then they will carry flows of different composition and it is within the scope of this invention to control the flows in the lines 26 in relation to one another so as to achieve a desired mixed flow composition at the hydrocylone inlet.
  • Figure 6 shows how the control arrangement of lines 26 and 26a of Figure 5 may be changed to facilitate control to achieve a desired mixture composition at the hydrocyclone inlet.
  • a single watercut meter 27 is interposed between the point at which the lines 26, 26a merge and the inlet of the hydrocyclone 28 to monitor the composition of the inlet mixture, and controls the flow in the lines 26, 26a, by controlling valves 27a in the lines 26,26a.
  • the lines 26 will be positioned to extract liquid such that the mixture supplied to the hydrocylone is water continuous.
  • the mixture supplied to the hydrocylone is water continuous.
  • the resultant mixture from the two lines 26 could be processed by the hydrocylone 28 and the risk of stable dispersion escaping over the weir plate 18 with the separated oil would be correspondingly reduced.
  • the additional liquid removed from the vessel is monitored by a watercut meter and is further separated in a hydrocyclone.
  • a watercut meter is a preferred way of monitoring the nature of the liquid extracted from the vessel since it can proved an accurate guide to the actual oil/water ratio of the liquid.
  • other less accurate forms of monitoring and control could be utilised in some applications, for example a device which determines simply whether the liquid mixture is water continuous or oil continuous could be used to control the flow in the line 26.
