Abstract
(EN)
The present invention relates to a system for cooling and condensing gas, which uses the energy of the fluid and comprises a gas supply line, a first vortex tube connected to the gas supply line, a second vortex tube connected to the first vortex tube, and a first heat exchanger connected to the second vortex tube and to the gas supply line. The system for cooling and condensing gas is a modular system that can be replicated and connected in series or in parallel to another modular system to obtain a cooler gas or a gas with greater mass flow than that obtained using a single modular system. In addition, the system of the invention is optionally connected to elements for heat recovery, pressure recovery, recirculation or ventilation to make use of the residual gas streams. Moreover, the system of the invention does not require energy additional to that obtained from the pressure of the supply line to obtain liquefied gas. The system of the invention also makes use of the pressure drop required between the activities of transporting and distributing compressed gas.

La presente invención corresponde a un sistema de enfriamiento y condensación de gas que utiliza la energía del fluido y comprende una línea de alimentación de gas, un primer tubo vortex conectado a la línea de alimentación de gas, un segundo tubo vortex conectado al primer tubo vortex y un primer intercambiador de calor conectado al segundo tubo vortex y a la línea de alimentación de gas. Dicho sistema de enfriamiento y condensación de gas es un sistema modular, el cual puede ser replicado y conectado en serie o en paralelo a otro sistema modular para obtener un gas más frío o con mayor flujo másico que el obtenido con un único sistema modular. Además, el sistema de la presente invención se conecta opcionalmente a elementos de recuperación térmica, recuperación de presión, recirculación o venteo para el aprovechamiento de las corrientes de gas residuales. Además el sistema de la presente invención no requiere energía adicional a la obtenida de la presión de la línea de alimentación para la obtención de gas licuado. Por otra parte, el sistema de la presente invención aprovecha la caída de presión que se exige entre las actividades de transporte y distribución de gas comprimido.

Ledit système de refroidissement et condensation de gaz est un système modulaire, lequel peut être répliqué et relié en série ou en parallèle à un autre système modulaire pour obtenir un gaz plus froid ou présentant un plus grand flux massique que celui obtenu avec un seul système modulaire. En outre, le système de la présente invention est relié éventuellement à des éléments de récupération thermique, de récupération de pression, de recirculation ou de mise à l'atmosphère pour l'exploitation des courants de gaz résiduels. De plus, le système de la présente invention ne nécessite pas d'énergie supplémentaire à celle obtenue de la pression de la conduite d'alimentation pour l'obtention de gaz liquéfié. D'autre part, le système de la présente invention exploite la chute de pression qui est requise entre les activités de transport et distribution de gaz comprimé.
