Definitions
- the present invention relates to a device for regasification of liquefied natural gas and cogeneration of cold fresh water and cold dry air.
- Liquefied natural gas, LNG, regasification systems mainly use four energy sources:
- patent PCTES2016070589 discloses the problems perfectly described in the literature of the state of the art, related to regasification devices by air circulation, the problems of regasification devices by supplying seawater on ORV and the problems of regasification devices by combustion of hydrocarbons.
- Patent PCTES2016070589 discloses a tube and shell regasification device with a condenser duct on its inner face and an evaporator on its outer face inside which saturated air circulates. The problem with this device is the limitation in its production capacity and the capital cost since the entire bundle of tubes inside which the humid air circulates is placed inside a casing. Limits on the casing diameter and capital cost of this vacuum proof casing limit the feasibility of this technology.
- the contribution of the working fluid in liquid phase through the outer wall of the condenser evaporator tube inside which the humid air circulates is a complex contribution that usually ends up forming a film of water or liquid working fluid and said liquid film limits the latent heat transfer coefficient, which makes it necessary to multiply the surface of the tubes with air inside them and to multiply the diameter of the outer casing, this being a limiting factor for the viability of said technology.
- the present invention seeks to solve one or more of the aforementioned drawbacks by means of a liquefied natural gas, LNG, regasification device, as defined in the claims.
- the liquefied natural gas, LNG, regasification device allows the cogeneration of cold fresh water and cold dry air, using chambers or tubes for exchanging latent heat and sensible heat, evaporators on its inner face and condensers on its outer face.
- the regasifier device is made up of the following components:
- At least one cryogenic conduit through which liquefied natural gas, hereinafter LNG, is introduced at one end and NG natural gas exits at the other end.
- This conduit can have flow control systems and security systems and with the proper contribution of external energy it can maintain the thermal gradient even at a controlled temperature inside its wall, as the current Open Rack Vaporizers, ORV, do.
- the at least one cryogenic conduit through which the LNG circulates and the resulting regasified NG exits is located inside at least one hermetic casing with the outside that supports vacuum conditions and inside which there is a working fluid in phase liquid and gas.
- the gaseous phase of the working fluid condenses on the outer face of the LNG tube.
- the working fluid in liquid phase that is inside the shell is then supplied to the inner evaporating face of the latent heat and sensible heat exchange chambers or tubes, condenser evaporators located outside the shell and that have vacuum conditions in their inside.
- the chambers or tubes of exchange of latent heat and sensible heat evaporators condensers are in vacuum conditions inside.
- the chambers or tubes for exchanging latent heat and sensible heat, condenser evaporators, are condensers on the outside, which is exposed to a flow of moist air through atmospheric pressure and they are evaporators on their inner face on which a working fluid is provided in liquid phase.
- the outer condensing face may be covered, at least in part, with a capillary structure of microgrooves, microgrooves, wick, sinter, or other capillary structure.
- a capillary structure is a structure with a design such that the fluid is dominated by the intermolecular forces of cohesion and adhesion such that the liquid-gas interface of the condensing fluid is curved throughout its length, dominating the intermolecular forces of cohesion and adhesion. accession.
- the inner evaporating face may be covered, at least in part, with a capillary structure of microgrooves, microgrooves, wick, sinter or other capillary structure in which pure water or other working fluid flows and evaporates in a capillary regime.
- the gaseous phase of the working fluid evaporated within the condenser evaporator chambers or tubes is channeled into the casing within which there is at least one cryogenic tube into which the LNG that is converted into NG is introduced.
- the regasification device can be compartmentalized in a series of casings within which there are successive sections of, at least one, cryogenic tube and which work between different temperature ranges.
- At least one heat pipe can be inserted between the at least one casing containing the at least one LNG cryogenic tube and the storage container. Collection of steam and surplus liquid from the condenser evaporator chambers or tubes.
- the at least one intercalated heat pipe allows the use of different working fluids with different solidification temperatures that prevent the solidification of the working fluid on the cryogenic LNG tube or on the condensing face of another tube or intermediate condenser evaporator chamber and prevents the formation of ice on the outer face of the condenser evaporator chambers or tubes and allows the introduction of sensible heat exchangers to create a scaling of working temperatures.
