Description
La présente invention concerne l'homogénéisation d'un fluide transporté dans une canalisation, et comportant deux phases non miscibles dont l'une est dispersable dans l'autre, qui est continue. Elle s'applique lorsque ces deux phases non miscibles présentent des densités différentes. Il s'agit par exemple d'homogénéiser un mélange de pétrole et d'eau circulant dans une canalisation de transport horizontale. L'eau constitue la phase dispersable. Elle se présente souvent dans un tel fluide sous la forme de paquets qui se rassemblent en partie basse. L'homogénéisation consiste à diviser ces paquets en gouttes réparties dans le volume du fluide, ceci notamment pour permettre une mesure correcte de sa teneur en eau.The present invention relates to the homogenization of a fluid transported in a pipeline, and comprising two immiscible phases, one of which is dispersible in the other, which is continuous. It applies when these two immiscible phases have different densities. This involves, for example, homogenizing a mixture of petroleum and water circulating in a horizontal transport pipe. Water constitutes the dispersible phase. It often occurs in such a fluid in the form of bundles which collect at the bottom. Homogenization consists in dividing these packets into drops distributed in the volume of the fluid, this in particular to allow a correct measurement of its water content.
Une telle mesure se fait en effet habituellement sur des échantillons prélevés périodiquement et automatiquement dans la canalisaton, et, pour que la mesure effectuée sur les échantillons représente la composition de l'ensemble du lot de fluide (cargaison), il est d'abord nécessaire que ce lot soit homogène conformément à la norme ISO 3171. Or les composants d'un tel mélange tendent à se séparer naturellement au moins lorsque sa vitesse de circulation est petite, par exemple inférieure à 1 m/s. Un dispositif d'homogénéisation doit donc intervenir un peu en amont du point où les échantillons sont prélevés. Par ailleurs, la taille des gouttelettes de la phase dispersée a de l'importance pour la mesure. Dans le cas d'une conduite de pétrole transportant aussi un peu d'eau il faut que le mélange parvenant au dispositif de mesure soit un pétrole contenant plusieurs gouttelettes d'eau par cm³ de mélange, avec un diamètre de gouttelette compris entre 2 et 0,5 mm au plus.Such a measurement is in fact usually done on samples taken periodically and automatically in the pipeline, and, so that the measurement made on the samples represents the composition of the entire batch of fluid (cargo), it is first necessary that this batch is homogeneous in accordance with standard ISO 3171. However, the components of such a mixture tend to separate naturally at least when its circulation speed is small, for example less than 1 m / s. A homogenization device must therefore intervene a little upstream from the point where the samples are taken. Furthermore, the size of the droplets of the dispersed phase is of importance for the measurement. In the case of an oil pipe also carrying a little water, the mixture arriving at the measuring device must be an oil containing several water droplets per cm³ of mixture, with a droplet diameter between 2 and 0 .5 mm at most.
Une homogénéisation peut par ailleurs être utile dans les cas suivants :
- quand une canalisation transporte un fluide polyphasique dont les phases ont tendance à se séparer (du fait de la gravité par exemple) et que cette séparation cause une gène à l'exploitation, une usure ou une corrosion anormales des conduites,
- en amont du point de raccordement d'une canalisation secondaire alimentant un utilisateur du fluide transporté, ceci pour que cet utilisateur reçoive un produit dont les deux phases sont dans les bonnes proportions,
- quand on veut mélanger en ligne, à des fins de fabrication d'un produit, deux constituants liquides.
- when a pipeline carries a multiphase fluid whose phases tend to separate (due to gravity, for example) and this separation causes a disturbance in operation, abnormal wear or corrosion of the pipes,
- upstream of the connection point of a secondary pipe supplying a user of the transported fluid, this so that this user receives a product whose two phases are in the right proportions,
- when we want to mix online, for the purpose of manufacturing a product, two liquid constituents.
On connaît déjà, par exemple par les brevets britanniques n° 2.030.96 (JISKOOT Autocontrol Ltd) et européen n° 0060634 (Moore, Barrett and Redwood Ltd), divers procédés d'homogénéisation d'un fluide transporté dans une canalisation.Already known, for example from British patents No. 2,030.96 (JISKOOT Autocontrol Ltd) and European No. 0060634 (Moore, Barrett and Redwood Ltd), various methods of homogenization of a fluid transported in a pipeline.
Le procédé selon le brevet européen n° 0060634 comporte les opérations suivantes qui sont communes, quant à certains de leurs effets, à ce procédé connu et au procédé selon l'invention :
- on aspire dans une conduite de soutirage une fraction minoritaire du débit du fluide qui circule dans cette canalisation de transport
- on pressurise le fluide ainsi aspiré (dans une pompe de circulation disposée en sortie de la conduite de soutirage),
- et on fournit le fluide ainsi pressurisé à des buses d'injection de manière à former dans cette canalisation de transport des jets transversaux créant des tourbillons.
- a minority fraction of the flow rate of the fluid circulating in this transport pipe is sucked into a drawing-off pipe
- the fluid thus sucked is pressurized (in a circulation pump disposed at the outlet of the withdrawal pipe),
- and the fluid thus pressurized is supplied to injection nozzles so as to form in this transport pipe transverse jets creating vortices.
Ce procédé connu a été conçu pour réaliser l'homogénéisation par brassage du mélange. Il est notamment applicable au transport de pétrole mélangé d'eau. Il permet d'obtenir une certaine homogénéisation mais présente les inconvénients suivants :
- d'une part la puissance de la pompe de circulation doit être élevée en raison en particulier de la nécessité d'injecter un débit représentant une fraction relativement importante du débit total pour que le brassage induit soit suffisant,
- d'autre part il ne permet pas de dissocier la phase à disperser en gouttelettes de dimensions bien connues et suffisamment petites, ce qui ne garantit pas contre une décantation ou une coalescence ultérieures trop rapides des gouttes de la phase dispersée, ni par conséquent contre le risque de fausser la mesure par échantillonnage.
- on the one hand, the power of the circulation pump must be high, in particular because of the need to inject a flow rate representing a relatively large fraction of the total flow rate for the induced mixing to be sufficient,
- on the other hand, it does not make it possible to dissociate the phase to be dispersed into droplets of well-known and sufficiently small dimensions, which does not guarantee against too rapid decantation or subsequent coalescence of the drops of the dispersed phase, nor consequently against the may distort the measurement by sampling.
La présente invention a pour buts d'obtenir d'améliorer l'homogénéisation et/ou de limiter la puissance de pompage nécessaire.The present invention aims to obtain improved homogenization and / or to limit the pumping power required.
L'amélioration de l'homégénéisation peut s'exprimer de deux manières :
- d'une part la taille des gouttes de la phase dispersée est diminuée,
- d'autre part les gouttes de petite taille ou gouttelettes ainsi formées sont bien dispersées et leur nombre par cm³ de mélange est relativement uniforme.
- on the one hand, the size of the drops of the dispersed phase is reduced,
- on the other hand the small drops or droplets thus formed are well dispersed and their number per cm³ of mixture is relatively uniform.
La limitation de puissance de pompage peut s'exprimer par le fait que la puissance demandée à la pompe de circulation pour obtenir une telle homogénéisation améliorée n'est pas sensiblement plus importante que celle nécessaire selon les procédés connus.The limitation of pumping power can be expressed by the fact that the power required from the circulation pump to obtain such an improved homogenization is not significantly greater than that necessary according to known methods.
Par ailleurs la présente invention vise à atteindre ces buts sans que le dispositif utilisé pour cela présente un encombrement longitudinal gênant.Furthermore, the present invention aims to achieve these goals without the device used for this having a troublesome longitudinal bulk.
Ces buts sont atteints selon l'invention par le procédé tel qu'il est défini dans la revendication 1. En ce qui concerne certaines caractéristiques de mise en oeuvre préférée de ce procédé, référence est faite aux sous-revendications.These objects are achieved according to the invention by the method as defined in claim 1. With regard to certain characteristics of preferred implementation of this method, reference is made to the subclaims.
Ces choix sont faits notamment à partir des considérations suivantes :
Pour dissocier une phase en gouttelettes de dimensions connues, il faut dissiper une énergie E par unité de volume du produit et le diamètre d des gouttelettes est une fonction directe de E. Or un jet qui débouche dans un milieu liquide dissipe, par unité de volume transporté par ce jet, une puissance fonction de la vitesse V du jet et de son diamètre D. La puissance de la pompe de circulation et les caractéristiques des conduits et des buses doivent donc être choisies de façon qu'on obtienne pour le jet les valeurs de V et de D telles que les gouttes formées avec la phase dspersée aient le diamètre voulu ou un diamètre plus petit.These choices are made in particular on the basis of the following considerations:
To dissociate a phase into droplets of known dimensions, it is necessary to dissipate an energy E per unit of volume of the product and the diameter d of the droplets is a direct function of E. Or a jet which opens into a dissipated liquid medium, per unit of volume transported by this jet, a power depending on the speed V of the jet and its diameter D. The power of the circulation pump and the characteristics of the conduits and nozzles must therefore be chosen so that the values for the jet are obtained of V and D such that the drops formed with the dispersed phase have the desired diameter or a smaller diameter.
Par ailleurs l'énergie dissipée par unité de volume et par suite l'efficacité de la dissociation sont accrues si on utilise des jets concourants ou des jets arrêtés brutalement par un obstacle fixe.Furthermore, the energy dissipated per unit volume and consequently the efficiency of dissociation are increased if using concurrent jets or jets stopped abruptly by a fixed obstacle.
Il est important que la dissipation d'énergie au voisinage des jets de pulvérisation intéresse vraiment les deux phases : si le jet ne comportait qu'une phase, au moment de la réinjection dans la conduite, une partie de son énergie pourrait se dissiper dans une phase sans avoir d'effet sur la dissociation en gouttelettes. Un mélange interne par aspiration en zone enrichie est donc utile préalablement au débouché du jet, de même qu'une dispersion préalable de la phase dispersable.It is important that the energy dissipation in the vicinity of the spray jets really interests the two phases: if the jet had only one phase, at the time of reinjection into the pipe, part of its energy could dissipate in a phase without having any effect on the splitting into droplets. An internal mixture by suction in a enriched zone is therefore useful prior to the outlet of the jet, as is a prior dispersion of the dispersible phase.
A l'aide des figures schématiques ci-jointes on va décrire ci-après, à titre non limitatif, comment l'invention peut être mise en oeuvre. Lorsqu'un même élément est représenté sur plusieurs figures il y est désigné par le même signe de référence.Using the attached diagrammatic figures, a description will be given below, without implied limitation, of how the invention can be implemented. When the same element is represented in several figures, it is designated therein by the same reference sign.
La figure 1 représente une vue d'un dispositif de mise en oeuvre du procédé selon l'invention en coupe par un plan passant par l'axe de la canalisation de transport.FIG. 1 represents a view of a device for implementing the method according to the invention in section through a plane passing through the axis of the transport pipe.
La figure 2 représente une vue du même dispositif en coupe par un plan II-II représenté sur la figure 1, et perpendiculaire à l'axe de la canalisation de transport.2 shows a view of the same device in section through a plane II-II shown in Figure 1, and perpendicular to the axis of the transport pipe.
Le dispositif d'homogénéisation décrit ci-après est applicable à un mélange transporté de pétrole et d'eau. Il comporte les éléments précédemment mentionnés.
La conduite de soutirage 4 aspire une fraction du débit du fluide à homogénéiser dans la canalisation de transport 2 qui est cylindrique et présente un axe horizontal 1. La pompe de circulation 6 est entrainée par un moteur non représenté pour pressuriser le fluide ainsi aspiré. La conduite d'injection ramene le fluide ainsi pressurisé dans la canalsation de transport. Elle comporte un tronçon 8 en sortie de la pompe 6, les deux couronnes d'injection circulaires 10 et 12 disposées dans la canalisation de transport 2, coaxialement à celle-ci, une rampe d'injection 14 en amont de ces couronnes, et des tubulures 16 et 18 alimentant la couronne intérieure 12 et la rampe 14 à partir de la couronne extérieure 10. Cette dernière est alimentée directement par le tronçon 8. Son diamètre est le plus grand qui permette de la loger aisément dans la conduite 2. La couronne intérieure 12 est disposée un peu en aval de la couronne extérieure et présente un diamètre approximativement moitié. Ces deux couronnes portent lesdites buses de pulvérisation 20, 22, 24 comme précédemment indiqué. La rampe 14 s'étend selon un arc de cercle coaxial au bas de la canalisation 2 et porte lesdites buses de prémélange 26.The homogenization device described below is applicable to a transported mixture of petroleum and water. It contains the elements previously mentioned.
The withdrawal pipe 4 sucks a fraction of the flow of the fluid to be homogenized in the transport pipe 2 which is cylindrical and has a horizontal axis 1. The circulation pump 6 is driven by a motor not shown to pressurize the fluid thus sucked. The injection line brings the pressurized fluid back into the transport pipe. It comprises a section 8 at the outlet of the pump 6, the two
L'entrée 4a de la conduite de soutirage 4 est au bas de la canalisation 2 en amont des couronnes et rampes d'injection 10, 12 et 14 et elle est munie d'un guide d'entrée 4b.The
Dans le cas d'une canalisation 2 présentant un diamètre de 76 cm et transportant un pétrole de viscosité moyenne voisine de 0,1 poise mélangé d'une faible proportion d'eau, variant par exemple autour de 10 %, chaque buse peut présenter, par exemple, un diamètre de 9 mm, et être alimentée sous une pression suffisamment élevée au-dessus de celle dans la canalisation de transfert, pour fournir une vitesse de sortie de buse de 15 à 20 mètres par seconde.In the case of a pipe 2 having a diameter of 76 cm and transporting an oil of average viscosity close to 0.1 poise mixed with a small proportion of water, varying for example around 10%, each nozzle may have, for example, a diameter of 9 mm, and be supplied with a sufficiently high pressure above that in the transfer line, to provide a nozzle output speed of 15 to 20 meters per second.
Le nombre de buses 20 de la couronne extérieure est de 12, de même que celui des buses 22 de la couronne intérieure opposées aux précédentes pour former lesdites paires extérieures. La couronne intérieure porte de plus trois paires intérieures de buses 24 opposées les unes aux autres, et selon une direction commune de jets horizontale et perpendiculaire à la canalisation 2.The number of
La couronne extérieure est formée par incurvation d'un tube de diamètre 60 mm. La couronne intérieure présente un diamètre externe de 40 cm et est formée d'un tube de diamètre 80 mm.The outer crown is formed by bending a tube with a diameter of 60 mm. The inner crown has an external diameter of 40 cm and is formed from a tube with a diameter of 80 mm.
Le nombre des buses de prémélange est cinq.The number of premix nozzles is five.
Pour permettre une extraction et une réinstallation facile de l'ensemble formée par la conduite d'injection avec ces couronnes et rampes, comme précédemment indiqué, cette conduite est fixée à un couvercle 27 venant obturer un "trou d'homme" 28 présentant la forme d'un tube cylindrique d'axe vertical coupant l'axe 1 de la canalisation de transport, et de même diamètre. Ce tube est constitué de tôle d'acier comme cette canalisation, avec soudure selon la ligne 30 d'intersection des deux. La conduite 8 se raccorde à la sortie de la pompe 6 par un raccord amovible 32.To allow easy extraction and reinstallation of the assembly formed by the injection pipe with these crowns and ramps, as previously indicated, this pipe is fixed to a
