Description
Vaporizador atmosférico optimizado.Optimized atmospheric vaporizer.
El invento de referencia se refiere a un gasificador atmosférico para gas natural licuado, que permite la utilización del intercambio de calor con el ambiente, incluso en condiciones muy desfavorables, con considerable ahorro energético y notable mejora en la seguridad de las instalaciones de regasificacion.The reference invention relates to a atmospheric gasifier for liquefied natural gas, which allows use of heat exchange with the environment, even in very unfavorable conditions, with considerable energy savings and notable improvement in the security of the facilities of regasification
La invención va dirigida al sector industrial fabricante de instalaciones de regasificación de Gas Natural licuado, destinadas a prestar servicio en aquellos lugares en los que no existe gaseoducto y se necesita gas natural para uso doméstico-comercial o industrial.The invention is directed to the industrial sector manufacturer of Natural Gas regasification facilities liquefied, intended to serve those places where that there is no gas pipeline and natural gas is needed for use Domestic-commercial or industrial.
Actualmente la practica totalidad de las plantas que se instalan utilizan vaporizadores de haz tubular o del tipo serpentín inundado para gasificar el gas natural licuado. Estos equipos necesitan calderas de alto consumo para calentar el agua que provocará la vaporización en el equipo.Currently almost all of the plants that are installed using tubular beam vaporizers or of the type flooded coil to gasify liquefied natural gas. These equipment needs high consumption boilers to heat water which will cause vaporization in the equipment.
En algunas plantas (en las de muy bajo consumo) hubo tímidos intentos de utilizar vaporizadores atmosféricos, de los que se usan para otros gases, pero no se han mostrado adecuados por su bajo rendimiento y no poder utilizarlos de forma continua todo el año, a valor nominal, como exige el gas natural licuado.In some plants (in those of very low consumption) there were timid attempts to use atmospheric vaporizers, of the which are used for other gases, but have not been shown adequate by its low performance and not being able to use them continuously all the year, at nominal value, as required by liquefied natural gas.
Ante las dos alternativas anteriores, se desprenden dos conclusiones: depender del uso de calderas –en marcha 24 horas al día- tiene un elevado número de averías con paro de plantas, además de un auto-consumo de gas muy importante, y ninguna de las dos opciones garantiza continuidad en el suministro y elimina la posibilidad de incidentes con paso de gas frío o liquido.Given the two previous alternatives, They draw two conclusions: depending on the use of boilers - on the move 24 hours a day - has a high number of breakdowns with stoppage of plants, in addition to a very self-consumption of gas important, and neither option guarantees continuity in the supply and eliminates the possibility of incidents with gas passage cold or liquid
La invención consiste en el diseño de gasificadores para gas natural en base al principio de intercambio calorífico con el ambiente, incluso a baja temperatura.The invention consists in the design of gasifiers for natural gas based on the exchange principle calorific with the environment, even at low temperature.
Estos gasificadores están diseñados en base a parrillas de tubos de 5 metros, situados en posición vertical, unidos en serie mediante codos (Fig. l).These gasifiers are designed based on 5 meter tube grills, located vertically, connected in series by elbows (Fig. l).
Los tubos del gasificador son de sección cilíndrica uniforme en toda su longitud, con diseño especifico de aleteado, tanto por la parte interior como exterior (Fig.2), al objeto de optimizar el parámetro de superficie equivalente de intercambio.The gasifier tubes are sectional uniform cylindrical throughout its length, with specific design of finned, both inside and outside (Fig. 2), at in order to optimize the equivalent surface parameter of exchange.
Las formas del aleteado interior y exterior se ha diseñado también para favorecer los flujos de gas internamente (Fig.2), evitando perdidas de cargas innecesarias, y al circulación del aire vehicular por el exterior.The shapes of the inner and outer finning have also designed to favor gas flows internally (Fig. 2), avoiding unnecessary load losses, and circulation of vehicular air outside.
El material seleccionado para este equipo es aluminio recocido, por su ligereza y rigidez estructural.The material selected for this equipment is annealed aluminum, for its lightness and structural rigidity.
La concepción del equipo de vaporización es del tipo modular, constituida en base a parrillas de 10 tubos de 5 metros de altura conectados en serie (Fig.1). Se pondrán tantas parrillas de tubos como cantidad de gas se desee vaporizar. El tiempo de saturación considerado en cálculos es de 8 horas, en servicio continuo a valor nominal en condiciones normales, por lo que se necesitarán 3 equipos para dar servicio continuado. La mínima temperatura de diseño en operación son -10°C sin aporte de aire u otro fluido a mayor temperatura.The conception of the vaporization equipment is of modular type, consisting of grills of 10 tubes of 5 height meters connected in series (Fig. 1). They will put so many tube grills as a quantity of gas you want to vaporize. He saturation time considered in calculations is 8 hours, in continuous service at nominal value under normal conditions, so 3 teams will be needed to provide continuous service. The Minimum design temperature in operation is -10 ° C without input from air or other fluid at a higher temperature.
