Abstract

A device for regasifying liquefied natural gas (LNG) and co-generating cool freshwater and cool dry air, which device comprises at least one hermetic outer recipient containing an intermediate fluid in liquid phase and gaseous phase, the fluid having high latent heat and high capillary properties, traversed by at least one intermediate fluid evaporation tube inside the tube flows moist air whose moisture condenses, at least partly, in a capillary condensation regime on its inner face and on its outer face the liquid phase of the intermediate fluid evaporates, at least partially, in a capillary evaporation regime, and traversed by at least one LNG evaporation tube on which outer face the gaseous phase of the intermediate fluid condenses at least partially, under a capillary condensation regime, and inside the tube, the LNG is heated and changes phase and the regasified natural gas (NG) is heated to a temperature greater than 5° C.

A regasification device for liquefied natural gas (LNG) and co-generation of cooler-than-ambient freshwater and air that is cooler-than-ambient and drier-than-ambient, the device comprising:

at least one external hermetic container containing an intermediate fluid in its liquid and gaseous phases;
an inside of the external hermetic container crossed by at least one intermediate fluid evaporation tube inside which a fluid that provides caloric energy to the device flows and on whose outer face the liquid phase of the intermediate fluid evaporates;
the inside of the external hermetic container crossed by at least one LNG evaporation tube configured so that when the fluid that provides caloric energy to the device flows through the at least one intermediate fluid evaporation tube, the gaseous phase of the intermediate fluid condenses on the LNG evaporation tube's outer face and in its interior LNG is heated and changes phase and the resulting regasified natural gas (NG) is heated up to a temperature greater than 5° C.;
wherein the fluid flowing in the interior of the at least one intermediate fluid evaporation tube is ambient air and the inner face of at least one intermediate fluid evaporation tube is coated at least in part with microslots, microgrooves, or sintering on which the water vapor contained in the ambient air undergoes capillary condensation.
