Description
1 2357710 APPARATUS FOR MIXING LIQUID IN A PIPELINE This invention is
concerned with apparatus for mixing liquid in a pipeline (such as a transfer fine), particularly with a liquid sampling system, for taking samples from crude oil pipelines although it may also be used for mixing in other applications such as blending oils or chemicals.
The rapid and predictable mixing of pipeline contents is useful in both process terms but also to allow samples to be taken from a single point on the cross section to represent accurately the overall composition. Examples of this are the representative sampling of crude oil or the on-line control of the ratios of several components being added together in response to a required result - for example density In particular, automatic collection of representative crude oil samples during liquid transfer operations has become increasingly important in recent years, both for batching operations, such as tanker unloading, and for pipeline operations. where the flow rate is variable but continuous. The collected samples, which are used for laboratory analysis or retained for reference, are particularly important when determining crude oil properties for fiscal purposes. It is therefore important that the sample should be taken from a homogeneous liquid flow, but this is difficult with conventional sampling systems in which a sampling probe is inserted into the transfer line, because of layering of the liquid in the transfer line due to the density difFerences and immiscibility of water, sand and oil which is particularly a feature of crude oil flow. Static mixers are unsatisfactory for several reasons - they can only be installed/serviced during shutdown but more importantly the mixing quality is defined by the turbulence (velocity) in the pipeline - static mixers add more turbulence (watts/Kg) by way of pressure drop as the flow rates increase. A static mixer designed to operate at low flow rates will create excessive mixing and excessive pressure loss at high rates i.e., the rangeability (the ratio between the maximum and minimum operating flows) is very limited It is known to provide a method of obtaining a homogeneous sample fi-om. a liquid 0 2 transfer line by removing liquid from the liquid transfer line and returning it to the transfer line through a return loop so that it re-enters the transfer line as a jet or jets of liquid which agitate the liquid in the transfer line to a substantially uniform mixture, and removing a sample from the uniform mixture. Such an apparatus is referred to is I a et-mixer. Jet Mixing adds progressively more watts/kg of mainline flow as the flow rates drop. The rangeability several orders of magnitude better than static mixing.
A portion of fluid representative of the whole cross section (i.e. sample) may be extracted either downstream of the whole mixing device or as an alternative from the mixing loop itself where the sample is removed from the return loop. The jet or jets at the outlet of the return loop (hereafter called the "jet assembly" to the transfer lline i, upstream of the inlet to the return loop and the distance between the inlet and outlet i and the flow velocity in the return loop are selected empirically to ensure that the liquid in the transfer line is uniformly mixed at the inlet to the return loop.
The original concept of jet mixers included a single jet nozzle, mounted in the wal. of the pipeline and was subsequently superseded by an internal mounted twin- jet arrangement mounted on an assembly Get assembly") which can be removQbly inserted into the pipeline through the pipeline wall, usually extending verticdly upwards ftom the lower side of the pipeline but sometimes extending downwards from the upper side. The twin-jet system is well established for many installations.
The twin-jet mixer comprises two opposing jet nozzles placed just inside the lo ver wall of the pipeline and arranged to direct the jets of liquid tangentially of the pipe with the jets of liquid directed in opposite directions. The jets are placed in the are of the pipe with the highest concentration of heavier components. By placing the jet nozzles in this area the water droplets are subject to a high shear zone thus reducing I their droplet size while the opposing liquid jets generated a helical swirl which distributes water droplets or denser components throughout the pipeline contents.
These two actions are complementary but generate a mixing system where the 3 &c residence" length (or effective mixing zone) depends significantly on the pipeline velocity.
The operation of this design is enhanced when there is adequate free length both upstream and downstream to provide a predictable flow regime to the mixing device.
Since the distribution quality is a function of pipeline length, under some circumstances difficulties arise in correctly placing the sample ofItake.
The present invention seeks improvement to the overall performance and efficiency of the mixing design to ensure better dispersion of the heavier components and to impart distribution over a shorter length.
According to the invention there is provided a jet assembly, for an installation for sampling liquid in a liquid transfer line comprising a return loop including a pump to remove liquid from the transfer line and return it to the transfer line as a jet or jets which agitate the liquid in the transfer line to a substantially homogeneous mixture, said jet assembly comprising a plurality of nozzles each configured to provide a jet of liquid directed upstream of the liquid flow in the transfer line.
In a preferred embodiment the apparatus for mixing liquid in a pipeline in accordance 0 with the invention will now be described by way of example only and with reference to the accompanying drawings in which:
Figure 1 illustrates diagrarnmatically a liquid sampling system for use in a pipeline, Figures 2 and 3) are transverse and axial sections through the end of the jet assembly which is inserted in the pipeline, Figure 4 shows a detail of the end of the jet assembly of Figures 2 to and -0 Figure 5 shows a general arrangement showing the jet assembly inserted in a pipeline and the liquid jets produced by the jet assembly.
4 Referring to Figure 1, crude oil passing through a pipeline 1 is intercepte y a or a return loop 3. Oil entering the retractable sampling probe 2 which forms the inlet f return loop 3 is returned to the pipeline 1 through one or more mixing jets 4 mounted on a retractable jet assembly 6. The flow velocity in the return loop 3 is generated by a pump 5 and, by suitable adjustment of the flow velocity and selection of the numbers and diameter of the n-fixing jets 4, the stream of oil re- entering the pip through the jets 4 from the return loop 3 agitates the crude oil in the pipeline 1 sufficiently to ensure that it is a homogeneous mixture when it reaches the prob 2 which is the inlet to the return loop 3).
Samples of the oil may be removed from return loop 3 of downstream in the pipel.ne by a conventional sampling procedure.
In the arrangement shown in Figure 1 the mixing jets 4 are provided on a retractable jet assembly 6 and the end portion 11 of the jet assembly 6 is shown in more detaL' in J Figures 2 to 5. The particular jet assembly 6 is of a type which is to be inserted from above the top of the pipeline (this is normally more convenient since a retract rig mechanism must be provided and there is normally more space above the pipel ne than below). Thus the jet assembly 6 will normally be inserted through a hole in ' he upper pipeline wall, the lower end 11 extending generally down to the lower most point of the circumference of the pipeline, the lower end 11 extending into the sediment-containing crude oil which tends to flow at the bottom of the pipeline.
As can be seen from Figures 2 to 4 the jet assembly 6 comprises a tubular member of suitable steel, the lower end 11 of the tubular member 12 being closed by a lovier closure plate 1 J3). Alternatively, the jet assembly 6 can be machined from a solid bar.
There are provided in the example shown a total of nine holes in the tubular member 12 in which are mounted nozzles 15 - 23. The nozzles are arranged Mi three sets, a first set 15 - 18 of nozzles arranged generally spaced along the length of the tubular member 12 in a line parallel to the axis, a second group 19 - 22 sin- filarly arranged but at an angle 120 degrees with respect to the first set 15 - 18, and a single nozzle 23 spaced mid way between the two sets 15 - 18 and 19 - 22. The exact configuration of spacing is clear from Figures 2 to 4.
As can be seen each nozzle comprises a cylindrical tube 24 which extends to a small extent outside the tubular member 12 and inwards into the manifold or plenum within the tubular member 12.
Figure 3 illustrates clearly the differing dispositions of the axes of each nozzle, the two lower nozzles 15,19 being disposed so that their axes are normal to the axis of the tubular member 12, and succeeding pairs 16, 20; 17,21; 18,22; being disposed at increasingly more upward angles. As can be seen from Figures 3) and 5 (in Figure 5, only the nozzle 23 is mounted in the tubular member 12 for clarity), the nozzle 23 is disposed so that its axis points slightly downwards rather than upwards as with the other nozzles. As is clear from Figures 2 and 5, the nozzle 24 points directly upstream and the remaining nozzles, instead of being transverse to the directional flow of the fluid, as has been the case in the past, point upstream to a predetermined extent.
As is clear from the drawing, the relative angular dimensions are as follows: - 1 From Figure2, angle A between axis of nozzle 24 and direction of fluid flow in the pipeline (indicated by arrow C) equals 180 degrees.
Angles B between each of nozzles 15 - 18, 19 - 23 and nozzle 24 equals 60 degrees.
From Figure 3), angle D between nozzles 15 and 19 and axis of pipeline equals 90 degrees.
From Figure 3, angle E between axes of nozzles 16 and 20 and axis of pipeline equals 82 degrees.
6 From Figure 3, angle F between axes of nozzles 17 and 21 and axis of pipeline equals 74 degrees.
From Figure 3, angle G between axes of nozzles 18 and 22 and axis of pipeline equals 68 degrees.
From Figure 4, angle H between the axis of the nozzle 24 and the axis of the pip(line is 95 degrees.
In other circumstances, the ranges of values of angles A, B, D - H are as follows:- A substantially zero B 40 - 75 deszrees D 80 - 100 degrees E -10 - 90 degrees F 60 - 90 degrees G 50 - 90 degrees H 80 - 110 degrees In use the jet assembly as shown is inserted into the pipeline and high pressure oil is recirculated throu'uh the nozzles 15 - 23. They provide jets 15J 2M at the angles described above and which are illustrated by the solid arrows in Figure 5. The jet 23J from the nozzle 23 is intended to impinge upon the lowermost wall of the pipeline so as to disturb the lowermost sediment level. The remaining nozzles provide jets 1M 25 22J which encourage a helical flow in opposite directions around the walls of pipeline to cause mixing of the sediment and water which is separated out at the bottom of the pipeline as quickly as possible. Because the oil is flowin2 through the pipeline at some speed., it tends to deflect the 30 jets 15J - 2M shown by the dotted arrows in the Figure 5 downstream and so the initial component of the jets upstream counteracts that.
7 There is thus provided a number of sideways and part forward and part upward disposed jets of liquid which can be individually sized as to their speed and angle by choice of bore of each nozzle and the angle at which each nozzle is provided in the jet assembly. In this way the bulk pipeline flow is directed and funnelled to ensure that maximum energy is dissipated toward the dispersion and break down of the droplets of the heavier components in the pipeline. The overall jet pattern establishes a pair of helical cells more quickly thereby reducing the length over which the energy transfer and thereby mixing takes place.
The use of a number of jets arranged in a splay pattern reduces the elfect of unexpected flow regimes in the pipeline being inadequately mixed. The use of a forward facing jet, particularly the lower jet 23J, ensure that any heavy material at the base of the pipeline is driven up into the mixing zone by causing a jet ramp.
In an alternative arrangement, not illustrated, whereby the jet assembly is inserted from the bottom of the pipeline, there is provided in the closure plate which in this case is at the top of the jet assembly, a nozzle pointing upwardly which ensures that all of the oil in the pipeline will pass close to a jet.
The invention is not restricted to the details of the foregoing example.
