Description
Le présent certificat d'addition concerne des perfectionnements au système de sécurité faisant l'objet du brevet principal, qui est destiné à éliminer tout risque d'entraînement de liquides au nez de torche ou à l'évent lors du torchage ou de la dispersion des gaz associés à la production ou au traitement d'hydrocarbures à terre et en mer.This certificate of addition relates to improvements to the safety system which is the subject of the main patent, which is intended to eliminate any risk of liquids entrained at the torch nose or in the vent during flaring or dispersion of the gases associated with the production or processing of hydrocarbons on land and at sea.
On rappelle que ce système fait intervenir, dans la chaîne d'écoulement des gaz, entre la source d'entraînement de liquides et le nez de la torche ou l'évent, au moins une capacité telle qu'un ballon de pied de torche, munie d'une colonne de trop-plein débouchant en dessous d'un niveau de liquide, par exemple la mer, à une distance déterminée de son piquage sur ladite capacité.It will be recalled that this system involves, in the gas flow chain, between the source of entrainment of liquids and the nose of the torch or the vent, at least one capacity such as a torch base balloon, provided with an overflow column opening below a liquid level, for example the sea, at a determined distance from its tapping on said capacity.
Un premier perfectionnement selon l'invention a pour but d'éviter, en cas de déversement de liquide dans la colonne de trop-plein, la rétention et le piégage de gaz dans le liquide déversé, ou en dessous de celui-ci, ce qui en résulterait un fonctionnement aléatoire de l'ensemble du système de sécurité précédemment décrit.A first improvement according to the invention aims to avoid, in the event of a liquid spill in the overflow column, the retention and trapping of gas in the spilled liquid, or below it, which this would result in random operation of the entire security system previously described.
Ce perfectionnement consiste donc à prévoir un circuit tel qu'un tube crépine intérieur à la colonne de trop-plein ou un conduit extérieur à celle-ci, de remontée des gaz, permettant l'évacuation jusque dans les installations situées en amont du tube de trop-plein, des gaz existants ou entraînés par les liquides dans la colonne de trop-plein.This improvement therefore consists in providing a circuit such as a strainer tube inside the overflow column or a duct outside of it, for raising the gases, allowing evacuation to the installations located upstream of the overflow, existing gases or liquids entrained in the overflow column.
L'invention a également pour objet un deuxième perfectionnement permettant d'améliorer la sécurité de fonc- , tionnement de la colonne de trop-plein, en détectant un niveau anormalement haut de liquide dans le susdit tube de trop-plein.The invention also relates to a second improvement making it possible to improve the operating safety of the overflow column, by detecting an abnormally high level of liquid in the above-mentioned overflow tube.
En effet, durant la vie de l'installation, le tube de trop-plein peut perdre sa qualité de sécurité par bouchage partiel ou total de celui-ci, soit par un redimensionnement ultérieur des installations placées en amont, conduisant à des débits de liquide pouvant être déversés dans la colonne de trop-plein incompatibles avec le dimensionnement initial de celle-ci.Indeed, during the life of the installation, the tube overflow may lose its quality of safety by partial or total blockage thereof, or by a subsequent resizing of the installations placed upstream, leading to flow rates of liquid which may be discharged into the overflow column incompatible with the initial dimensioning thereof.
Le deuxième perfectionnement du système de sécurité consiste donc, selon l'invention, à équiper la colonne de trop-plein de un ou plusieurs organes de détection permettant de détecter la présence d'hydrocarbures à un niveau anormal. Ces organes de détection peuvent consister en des détecteurs de niveau haut placés dans la partie aérienne de la colonne de trop-plein, ou en un ou plusieurs détecteurs de pression, différentiels ou non, placés plus généralement dans la partie basse de la colonne de trop-plein. Ces détecteurs peuvent également être conçus de manière à détecter la présence d'hydrocarbures par exemple par effet optique, par effet capacitif, par effet magnétique, par effet électromagnétique ou encore par mesure de phénomènes vibratoires.The second improvement of the security system therefore consists, according to the invention, in equipping the overflow column with one or more detection members making it possible to detect the presence of hydrocarbons at an abnormal level. These detection members may consist of high level detectors placed in the aerial part of the overflow column, or one or more pressure detectors, differential or not, placed more generally in the lower part of the overflow column. -full. These detectors can also be designed so as to detect the presence of hydrocarbons, for example by optical effect, by capacitive effect, by magnetic effect, by electromagnetic effect or also by measurement of vibratory phenomena.
Tous ces détecteurs peuvent être placés soit dans la colonne de trop-plein, soit à l'extérieur et peuvent être protégés ou non par une tubulure annexe.All these detectors can be placed either in the overflow column or outside and can be protected or not by an annexed tubing.
Ainsi, quel que soit le mode de détection et le ou les dispositifs utilisés, la détection de la présence d'hydrocarbures à un niveau anormal pourra permettre:
- - En cas de dérèglement de l'installation, de signaler son mauvais fonctionnement et éventuellement d'arrêter le débit des fluides dans l'installation, si le dérèglement ne peut être corrigé automatiquement ou non;
- - De vérifier périodiquement la capacité de service de l'ensemble du dispositif de sécurité par des moyens appropriés. ,
- - In the event of a disturbance in the installation, to report its malfunction and possibly to stop the flow of fluids in the installation, if the disturbance cannot be corrected automatically or not;
- - Periodically check the service capacity of the entire safety device by appropriate means. ,
Cette vérification peut par exemple consister en une injection d'eau à débit connu dans tout ou partie de l'ensemble du système de sécurité, l'injection étant effectuée en un point quelconque de l'installation, mais de façon à permettre la vérification du fonctionnement de tout ou partie du système de sécurité.This verification may for example consist of an injection of water at a known rate in all or part of the entire security system, the injection being carried out at any point of the installation, but of to allow verification of the operation of all or part of the security system.
L'invention a également pour objet un troisième perfectionnement permettant d'augmenter la capacité de rétention des liquides déversés et finalement d'améliorer la sécurité globale du système, en multipliant le nombre de colonnes de trop-plein, ceci, dans le but également, de ne pas créer de contraintes localisées trop importantes compte-tenu de la capacité de rétention recherchée.The subject of the invention is also a third improvement making it possible to increase the retention capacity of the spilled liquids and finally to improve the overall safety of the system, by multiplying the number of overflow columns, this, also for the purpose, not to create localized constraints that are too great, given the retention capacity sought.
A cet effet une multiplicité de tubes de trop-plein pourra être utilisée, ceux-ci pouvant être implantés dans des zones favorables, tout ou partie des structures sous-jacentes existantes pouvant par exemple être utilisées pour leur réalisation.For this purpose a multiplicity of overflow tubes can be used, these can be installed in favorable areas, all or part of the existing underlying structures can for example be used for their realization.
La mise en service de ces colonnes de trop-plein pourra si nécessaire être faite à la première mise en service de l'installation, ou partiellement différée dana. le temps suivant l'évolution requise de la capacité de l'installation. Chacune des colonnes de trop-plein est équipée si nécessaire des perfectionnements précédents.The commissioning of these overflow columns may if necessary be made when the installation is commissioned for the first time, or partially deferred dana. the time following the required change in the capacity of the installation. Each of the overflow columns is equipped with the previous improvements if necessary.
Des modes de réalisation de l'invention seront décrits ci-après, à titre d'exemples non limitatifs, avec référence aux dessins annexés dans lesquels:
- La figure 1 est une représentation schématique d'un système de sécurité dans lequel le tube de trop-plein est équipé d'un tube crépiné pour l'évacuation des gaz.

Comme précédemment mentionné, le système de sécurité sur lequel s'applique les perfectionnements selon l'invention est destiné à équiper des installations de , production d'hydrocarbures à terre et en mer.As previously mentioned, the safety system to which the improvements according to the invention apply is intended to equip installations for the production of hydrocarbons on land and at sea.
Ces installations peuvent comprendre, comme décrit dans le brevet principal, une source d'entraînement d'hydrocarbures liquides constituée par un séparateur recevant le pétrole brut ou le gaz par un conduit d'arrivée. Ce séparateur peut être équipé, de façon classique, d'un circuit de reprise normale de l'huile ou des condensats et d'une sortie de gaz raccordée à une chaîne d'écoulement de gaz jusqu'au nez de la torche.These installations may include, as described in the main patent, a drive source for liquid hydrocarbons constituted by a separator receiving crude oil or gas through an inlet pipe. This separator can be fitted, in a conventional manner, with a normal recovery circuit for oil or condensates and with a gas outlet connected to a gas flow chain up to the nose of the torch.
Cette chaine d'écoulement de gaz comporte, entre le séparateur et le nez de la torche, un ballon de pied de torche (ou équivalent) équipé, de façon classique d'un circuit de reprise des égouttures pouvant comprendre une pompe.This gas flow chain comprises, between the separator and the nose of the torch, a torch base balloon (or equivalent) equipped, in a conventional manner with a drip recovery circuit which may include a pump.
Ces installations comprennent en outre,selon le brevet principal,une colonne de trop-plein venant se piquer sur le ballon de pied de torche enun emplacement correspondant à un niveau maximal prédéterminé et débouchant en dessous du niveau de la mer à une distance prédéterminée, en dessous du piquage sur ledit ballon.These installations further comprise, according to the main patent, an overflow column coming to be stuck on the torch foot ball at a location corresponding to a predetermined maximum level and opening out below the sea level at a predetermined distance, below the stitching on said balloon.
Toutefois, dans un but de simplification et de clarté on n'a représenté sur les figures 1 et 2 du présent certificat d'addition,qu'une partie de l'installation comprenant un ballon pied de torche 1,monté en bout de la chaîne dtentrainement des gaz 2 et connecté, dans sa partie supérieure, au fût de torche 3. Sur ce ballon pied de torche 1 vient en outre se piquer une colonne de trop-plein 4, en un emplacement correspondant à un niveau maximal prédéterminé, et débouchant en dessous du niveau 5, 6 de la mer.However, for the sake of simplicity and clarity, only part of the installation comprising a torch base balloon 1, mounted at the end of the chain, has been shown in FIGS. 1 and 2 of this certificate of addition. d t entrainment of

Il convient de préciser que, de préférence le point de piquage 10 du tube crépiné sera situé en un point du circuit de mise à l'atmosphère des gaz, tel que la séparation des liquides, éventuellement entraînés par les gaz remontants, puisse s'effectuer avant la mise à l'atmosphère des gaz.It should be specified that, preferably the point of tapping 10 of the strainer tube will be located at a point in the circuit for venting the gases, such that the separation of the liquids, possibly entrained by the rising gases, can be carried out before venting the gases.
En outre, la partie horizontale ou subhorizontale 12 de la colonne de trop-plein 4 pourra, de préférence, mais non nécessairement, déboucher tangentiellement dans la partie verticale ou subverticale de la colonne de trop-plein 4, afin de minimiser le piégeage ou l'entrat- nement de gaz dans ladite colonne 4. Dans le même but, la surface intérieure de l'extrémité supérieure de la partie verticale de la colonne de trop-plein 4 pourra, de préférence mais non nécessairement, être équipée de dispositifs, par exemple des ailettes de guidage ou des rampes hélicoïdales générant un mouvement hélicoïdal de liquides descendants dans la colonne de trop-plein 4, ceci afin de favoriser l'écoulement des liquides descen- dantset créer une cheminée centrale pour l'évacuation des gaz piégés en dessous des liquides ou entrainés par ceux-ci. Selon la position géographique de l'installation sur laquelle le système de sécurité sera installé, le sens d'enroulement, des rampes de guidage par exemple, sera dépendant de l'hémisphère terrestre sur laquelle elle se situe, (pour tenir compte des forces de Coriolis).In addition, the horizontal or subhorizontal part 12 of the
La figure 2 concerne un deuxième mode de réalisation d'un circuit permettant l'évacuation des gaz à l'intérieur de la colonne de trop-plein 4. Ce circuit qui permet d'obtenir des effets analogues à ceux obtenus à l'aide du tube crépine précédemment décrit, se distingue cependant de celui-ci,par le fait qu'il fait intervenir pour l'évacuation des gaz piégés dans la colonne de trop-plein 4, un tube d'évacuation 13 placé à l'extérieur.FIG. 2 relates to a second embodiment of a circuit allowing the evacuation of the gases inside the
Ce tube d'évacuation 13 (vertical) qui est placé sensiblement parallèlement à la colonne de trop-plein 4 communique avec ce dernier par une série de tubulures 14 éventuellement horizontales permettant l'évacuation des gaz piégés à différents niveaux.This discharge tube 13 (vertical) which is placed substantially parallel to the
