  • Patent number: 11662156
    Abstract: The invention relates to an arrangement for a latent-heat exchanger chamber, usable in distillation devices, which comprises an evaporator in a capillary evaporation regime on the inner face thereof and a condenser in a capillary condensation regime on the outer face thereof, with a system for the dosed supply of liquid into microgrooves or micro undulations of the inner evaporator face, preventing the formation of thin films of water on the evaporator face, the arrangement achieving high latent-heat transfer coefficients.

  • Patent number: 11619352
    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.

  • Patent number: 11209217
    Abstract: The invention relates to a mechanical vapour compression (MVC) desalination arrangement having a low compression ratio, with latent-heat exchangers having a high latent-heat exchange coefficient, with a temperature gradient between primary vapour and secondary vapour of approximately 1° C. or less, a compression ratio of 1.11 or less, high vapour volume, low overheating and a low-temperature saline solution to be desalinated, which arrangement allows industrial desalination with less specific energy per unit of desalinated water and is coupled to 100% renewable off-grid energy sources.

  • Patent number: 10203161
    Abstract: Condenser-evaporator tube, in whose interior flows a vapor to be condensed and over which flows a liquid to be evaporated, where both inside and outside faces of this tube are covered with capillary structures configured for the formation of liquid menisci having a contact angle smaller than 90° where the liquid-vapor interface curves, which allows capillary condensation inside the tube and evaporation on the outside face at the upper end (25) of the liquid menisci where the liquid layer is thinnest and the evaporation most efficient.
