Description

La présente invention concerne un procédé et une installation permettant l'injection d'au moins un additif dans un produit principal, l'injection de cet additif se faisant proportionnellement à un volume de référence dudit produit principal.The present invention relates to a method and an installation allowing the injection of at least one additive into a main product, the injection of this additive being made in proportion to a reference volume of said main product.

L'invention trouve une utilisation particulièrement intéressante dans l'additivation des produits pétroliers destinés à la consommation domestique ou industrielle.The invention finds a particularly advantageous use in the additivation of petroleum products intended for domestic or industrial consumption.

En effet, pour distribuer ces produits pétroliers, qu'ils soient constitués par des fuels lourds, des fuels domestiques ou des hydrocarbures légers, on procède généralement de la manière suivante.In fact, to distribute these petroleum products, whether they consist of heavy fuel oils, household fuels or light hydrocarbons, the procedure is generally as follows.

Des citernes mobiles sont positionnées devant des bras de remplissage, ces citernes sont remplies d'un volume défini du produit, puis en fonction de la destination de ces citernes et de la nature du produit ainsi que du volume du produit, une quantité prédéterminée d'additifs est injectée dans la citerne.Portable tanks are positioned in front of filling arms, these tanks are filled with a defined volume of product, then according to the destination of these tanks and the nature of the product as well as the volume of the product, a predetermined quantity of additives is injected into the tank.

Or pour une même installation de remplissage, il est souvent nécessaire de prévoir l'addition de plusieurs additifs différents, cette addition devant prendre en compte la nature de l'additif à injecter et permettre le rinçage de l'installation entre l'addition de deux additifs différents.However, for the same filling installation, it is often necessary to provide for the addition of several different additives, this addition having to take into account the nature of the additive to be injected and allow the installation to be rinsed between the addition of two different additives.

La présente invention prévoit donc un procédé qui permette l'injection dans un volume déterminé de produit principal, d'un additif, cet additif étant choisi parmi un groupe pré-établi d'additifs, et étant injecté selon un volume prédéterminé en fonction de sa nature et en fonction du volume du produit principal.The present invention therefore provides a method which allows the injection into an established volume of main product, of an additive, this additive being chosen from a pre-established group of additives, and being injected according to a predetermined volume according to its nature and according to the volume of the main product.

De façon à ce que le procédé permette le rinçage de l'installation entre l'additivation de produits différents, l'invention prévoit que le volume du produit principal en fonction duquel est prédéterminé le volume d'additif est divisé en volumes de références et en ce que une quantité d'additif est injectée pour chaque volume de référence. Selon une caractéristique complémentaire du procédé selon l'invention, l'injection de l'additif est initialisée en même temps que l'injection du volume de référence.So that the process allows the installation to be rinsed between the addition of different products, the invention provides that the volume of the main product according to which the volume of additive is predetermined is divided into reference volumes and into what a quantity of additive is injected for each reference volume. According to a complementary characteristic of the method according to the invention, the injection of the additive is initialized at the same time as the injection of the reference volume.

L'intérêt de ce procédé par injection selon des volumes de référence réside essentiellement dans le fait que, comme le volume d'additifs est en général inférieur audit volume de reférence du produit principal, l'installation permettant la mise en oeuvre de ce procédé est systématiquement nettoyée par le produit principal après chaque addition d'additif.The advantage of this injection process according to reference volumes lies essentially in the fact that, as the volume of additives is generally less than said reference volume of the main product, the installation allowing the implementation of this process is systematically cleaned by the main product after each addition of additive.

Mais l'invention prévoit aussi une installation d'injection d'un additif dans un produit principal, permettant l'injection d'une quantité déterminée dudit additif, ladite quantité étant proportionnelle à un volume de référence dudit produit principal, ledit additif pouvant être choisi parmi un groupe d'additifs, ladite installation comportant un moyen d'injection permettant l'injection dudit additif.However, the invention also provides an installation for injecting an additive into a main product, allowing the injection of a determined quantity of said additive, said quantity being proportional to a reference volume of said main product, said additive being able to be chosen among a group of additives, said installation comprising an injection means allowing the injection of said additive.

Selon l'invention, ledit moyen d'injection est relié à des moyens de stockage des additifs constituant ledit groupe par autant de canalisations secondaires qu'il y a d'additifs et par l'intermédiaire d'une canalisation commune, elle-même reliée aux canalisations secondaires par un manifold et comportant un moyen de comptage du volume d'additifs débité, chaque canalisation secondaire comportant une électro-vanne actionnée par un moyen de commande permettant de commander l'ouverture de la vanne en fonction du volume d'additif débité, l'injection se faisant en amont du moyen de comptage du produit principal.According to the invention, said injection means is connected to means for storing the additives constituting said group by as many secondary pipes as there are additives and by means of a common pipe, itself connected to the secondary pipes by a manifold and comprising a means of counting the volume of additives delivered, each secondary pipe comprising a solenoid valve actuated by a control means making it possible to control the opening of the valve as a function of the volume of additive delivered , the injection being made upstream of the counting means of the main product.

Selon une caractéristique complémentaire, chacune desdites canalisations secondaires comporte une pompe alimentaire permettant la mise sous pression de l'additif à injecter.According to an additional characteristic, each of said secondary pipes comprises a food pump allowing the additive to be injected under pressure.

Le moyen de commande est de préférence constitué par un calculateur qui établit un signal d'ouverture des électro-vannes en fonction d'un signal de mesure venant du moyen de comptage du volume d'additif débité, d'un signal de mesure indiquant le volume du produit principal injecté et d'un signal correspondant à la nature de l'additif à injecter.The control means is preferably constituted by a computer which establishes an opening signal of the solenoid valves as a function of a measurement signal coming from the means for counting the volume of additive delivered, of a measurement signal indicating the volume of the main product injected and a signal corresponding to the nature of the additive to be injected.

Mais l'invention sera mieux comprise à la lecture de la description suivante, faite d'une manière nullement limitative mais purement illustrative en référence à la figure annexée.However, the invention will be better understood on reading the following description, given in a non-limiting but purely illustrative manner with reference to the appended figure.

On a représenté sur cette figure une installation selon l'invention mise en place dans une installation de dépôt de super carburant.There is shown in this figure an installation according to the invention implemented in a super fuel deposition installation.

Cette installation comporte un bras (1) permettant l'injection du produit principal en provenance du réservoir (2). Ce bras (1) comporte un compteur volumétrique (3) replié à une centrale de calculs (4) de façon à pouvoir donner à l'entrée (5) de cette centrale un signal représentatif du volume du produit principal injecté.This installation comprises an arm (1) allowing the injection of the main product from the reservoir (2). This arm (1) comprises a volumetric counter (3) folded back to a computing center (4) so as to be able give the input (5) of this central unit a signal representative of the volume of the main product injected.

Cette installation comporte en outre six lignes secondaires pour l'injection des additifs (référence 6, 7, 8, 9, 10 et 11), chacune de ces lignes est reliée à une capacité d'alimentation telle que (12) par l'intermédiaire d'une pompe alimentaire (13)et d'un clapet anti-retour (35). Chacune de ces capacitésd'alimentation telle que (12) est elle-même alimentée à partir d'une cuve de stockage (14) par l'intermédiaire d'une pompe de transfert (15).This installation also includes six secondary lines for the injection of additives (references 6, 7, 8, 9, 10 and 11), each of these lines is connected to a supply capacity such as (12) via a food pump (13) and a non-return valve (35). Each of these supply capacities such as (12) is itself supplied from a storage tank (14) via a transfer pump (15).

Entre la pompe (13) et la tête d'injection (1), chacune des lignes secondaires telle que (6) comporte un robinet à pointeau (20) et une électro-vanne (21). Les lignes secondaires (6, 7, 8, 9, 10 et 11) sont reliées à l'extrémité de la ligne principale par un manifold (22) et un compteur volumétrique (23) et un clapet anti-retour (24) Ce compteur (23) envoie sur la centrale de commande (4) un signal représentatif du volume d'additif injecté. Cette centrale de calcul (4) prend en compte aussi des informations sur la nature de l'additif soit par l'entrée (30) reliée à une "boîte à clés" permettant de sélectionner manuellement un code correspondant à l'additif voulu, soit par l'entrée (32) qui est une liaison informatique avec un dispositif central d'automatisation du dépôt.Between the pump (13) and the injection head (1), each of the secondary lines such as (6) comprises a needle valve (20) and a solenoid valve (21). The secondary lines (6, 7, 8, 9, 10 and 11) are connected to the end of the main line by a manifold (22) and a volumetric counter (23) and a non-return valve (24) This counter (23) sends to the control unit (4) a signal representative of the volume of additive injected. This central computing unit (4) also takes into account information on the nature of the additive, either via the input (30) connected to a "key box" allowing manual selection of a code corresponding to the desired additive, or by the entrance (32) which is a computer link with a central deposit automation device.

L'installation ainsi représentée fonctionne de la manière suivante.The installation thus represented operates in the following manner.

L'opérateur par l'intermédiaire de la boîte à clés (31) ou du dispositif informatique (32) sélectionne la nature de l'additif choisi.The operator via the key box (31) or the computer device (32) selects the nature of the additive chosen.

La centrale, en fonction de la nature de l'additif choisi, détermine le lot d'additif à injecter pour chaque volume de référence. La détermination du lot est faite en fonction d'une proportion mémorisée et fixée par apprentissage. Pour injecter, la centrale actionne l'ouverture de l'électro-vanne (21) et prend en compte le volume d'additif introduit dans la citerne, ce volume lui étant communique par le signal en provenance du compteur (23).The control unit, depending on the nature of the additive chosen, determines the batch of additive to be injected for each reference volume. The batch is determined based on a proportion memorized and fixed by learning. To inject, the central unit opens the solenoid valve (21) and takes into account the volume of additive introduced into the tank, this volume being communicated to it by the signal from the counter (23).

Une fois le volume de référence de produit principal livré et la livraison continuant, la centrale commande de nouveau l'injection du lot d'additif correspondant au volume de référence et ainsi de suite jusqu'à ce que la livraison de produit principal soit terminée.Once the reference volume of main product has been delivered and delivery continues, the control unit again orders the injection of the batch of additive corresponding to the reference volume and so on until the delivery of main product is completed.

Le volume de référence est choisi comme étant un sous-multiple du volume total de la citerne à remplir. Comme les citernes utilisées contiennent un volume multiple de 1000 litres, le volume de référence est choisi comme étant égal à 1000 litres.The reference volume is chosen as being a submultiple of the total volume of the tank to be filled. As the tanks used contain a multiple volume of 1000 liters, the reference volume is chosen to be equal to 1000 liters.

L'injection par lot d'additif dans la première phase de la livraison d'une quantité de référence du produit principal permet de rincer la canalisation principale de toute présence d'additif en fin de livraison et ainsi de limiter la pollution du produit principal par un additif de nature non conforme d'une livraison sur l'autre, la pollution est alors limitée au seul volume compris entre l'électro-vanne (21) et le clapet anti-retour (24), ledit volume est minimisé par construction.The injection of a batch of additive in the first phase of the delivery of a reference quantity of the main product makes it possible to rinse the main pipe of any presence of additive at the end of delivery and thus to limit the pollution of the main product by an additive of a non-conforming nature from one delivery to the next, pollution is then limited to the only volume between the solenoid valve (21) and the non-return valve (24), said volume is minimized by construction.
