Description

SECTOR DE LA TÉCNICA SECTOR OF THE TECHNIQUE

La invención se encuadra en el sector técnico de las instalaciones petrolíferas, más concretamente en lo relativo al aumento de la seguridad y la sostenibilidad de dichas instalaciones. The invention falls within the technical sector of oil facilities, more specifically regarding the increase of the security and sustainability of said facilities.

La finalidad del doble contenimiento es evitar que el deterioro externo de los tanques enterrados produzcan fugas de los hidrocarburos que contienen. The purpose of double containment is to prevent the external deterioration of buried tanks produce leaks of the hydrocarbons they contain.

Los sistemas de control actuales, muy precisos y sofisticados, indican que se ha producido un derrame, e incluso la cantidad de hidrocarburo derramado, pero no evitan el derrame. Current control systems, very precise and sophisticated, indicate that there has been a spill, and even the amount of spilled oil, but do not prevent spillage.

Con el doble contenimiento y con sistemas de control de fugas, situados en el medio de las dos capas, no solo se detectan las posibles fugas, sino que nunca se puede producir un derrame, pues siempre quedara una capa de contención. With double containment and leak control systems, located in the middle of the two layers, not only possible leaks are detected, but a spill can never occur, because there will always be a layer of contention.

ESTADO DE LA TÉCNICA STATE OF THE TECHNIQUE

Actualmente en el mercado existen varios sistemas de doble contenimiento de tanques con diferentes procedimientos y utilizando diversos productos. En este documento se propone un nuevo procedimiento para realizar el doble contenimiento de tanques, mediante la utilización de poliurea. Currently in the market there are several double tank containment systems with Different procedures and using different products. This document proposes a new procedure to double contain tanks, through the use of polyurea.

DESCRIPCIÓN DETALLADA DE LA INVENCIÓN. DETAILED DESCRIPTION OF THE INVENTION.

Los tanques, en el contexto general, se fabrican en acero, poliester, fibra, polietileno. Por lo general los tanques construidos con acero en la capa exterior, la interior puede ser de acero, de poliester o fibra. Los tanques construidos con la capa exterior de poliester o fibra, los interiores, también, son de poliester o fibra. The tanks, in the general context, are manufactured in steel, polyester, fiber, polyethylene. Usually tanks built with steel in the outer layer, the inner one can be made of steel, of polyester or fiber. Tanks built with the outer layer of polyester or fiber, the interiors, Also, they are polyester or fiber.

El producto usado, la poliurea, es un recubrimiento extremadamente duradero debido a sus propiedades mecánicas y a sus cualidades químicas. Este recubrimiento altamente resistente tolera además los daños que pudieran ocasionar varios ácidos y químicos alcalinos, así como productos a base de petróleos, con excelente comportamiento y bacteriológicamente estable, fácil de limpiar y capaz de sellar juntas y esquinas. Es un material, en la actualidad, usado para multiples aplicaciones. La novedad de la invención reside en la utilización, por primera vez, de este producto para el recubrimiento de tanques de combustible.

VENTAJA TÉCNICA QUE APORTA LA INVENCIÓN El tiempo de aplicación, una vez el tanque abierto y limpio, es de 4 a 6 horas dependiendo del volumen del tanque. Según procedimiento de aplicación MAGA T ANK, el tiempo de secado de los puntos de imprimación es de unas 2 horas, dependiendo de la humedad y temperatura, el tiempo de secado al tacto de la capa aplicada y siguiente aplicación es de 15 segundos, que es un tiempo insignificante considerándose aplicación continuada. El tiempo de secado total es de 24 horas, pudiéndose acortar dicho tiempo con la aportación de calor. No afectando el tiempo de curado para que paralelamente se puedan realizar las pruebas de estanqueidad de la nueva capa. Por tanto, el tiempo inferior empleado en la actuación es una ventaja de este sistema, respecto al resto; pudiendo por tanto, empezar a utilizarse el tanque mucho antes. Otra ventaja del sistema es el inferior coste del producto y aplicación. El valor de la doble capa con poliurea es inferior a cualquier otro tipo de aplicación. El valor se da en función de la capacidad del tanque. Los comparativos con el valor de mercado nos dan como resultado costes inferiores en un 20 %. TECHNICAL ADVANTAGE OF THE INVENTION The application time, once the tank is open and clean, is 4 to 6 hours depending on the volume of the tank. According to MAGA T ANK application procedure, the drying time of the primer points is about 2 hours, depending on the humidity and temperature, the touch drying time of the applied layer and next application is 15 seconds, which is an insignificant time considering continued application. The total drying time is 24 hours, being able to shorten this time with the contribution of heat. Not affecting the curing time so that parallel testing of the new layer can be performed. Therefore, the lower time spent in acting is an advantage of this system, compared to the rest; being able therefore to start using the tank much earlier. Another advantage of the system is the lower cost of the product and application. The value of the double layer with polyurea is lower than any other type of application. The value is given based on the capacity of the tank. Comparisons with market value result in lower costs by 20%.
