The present invention relates to a heat exchange system comprising:—a single apparatus (N) having an area immersed in a fluid bath (N2) and a free space (N1) at the head in which a vapour phase is accumulated,—at least one interspace (P) open at both ends, situated inside said apparatus and completely immersed in the fluid bath,—one or more heat exchange surface (s) (6, 7, 8, 9, 10, 11), said system characterized in that it contains all the heat exchange surfaces in a single apparatus and said surfaces are completely immersed in the fluid bath and are fluidly connected to the hot and cold sources, external to said system, through flows of matter. At least one of the heat exchange surfaces (6, 7, 8) is situated inside the interspace and at least another surface (9, 10, 11) is situated in the space between said interspace and the walls of the apparatus.
A heat exchange system comprising:
The heat exchange system according to at least one of the claims from 1 to 2, which also comprises at least one steam turbine coupled with at least one electric generator.
The heat exchange system according to at least one of the claims from 1 to 3, wherein the heat exchange surfaces are in the form of helicoidal elements in which the streams of material flow.
The heat exchange system according to at least one of the claims from 1 to 4, wherein the interspace is cylindrically shaped.
The heat exchange system according to at least one of the claims from 1 to 5, wherein the fluid is water and the vapour phase is steam.
The heat exchange system according to at least one of the claims from 1 to 6, wherein the external hot sources and the cold sources represent the steps for the production process of hydrogen and/or synthesis gas.
The heat exchange system according to at least one of the claims from 1 to 7, wherein there are at least three inlet gates for the flow of cold material, and at least three inlet gates for the flow of hot material.
The heat exchange system according to at least one of the claims from 1 to 8, wherein there are at least six heat exchange surfaces.
The heat exchange system according to at least one of the claims from 1 to 10, wherein the flows of cold material are reagents, oxidants and/or inert products coming from the same catalytic partial oxidation process.
The heat exchange system according to at least one of the claims from 1 to 10, wherein the flows of hot material are products coming from at least a catalytic partial oxidation reaction step, a Water Gas Shift step and/or a combustion step of the same catalytic partial oxidation process.
A heat exchange and recovery process, characterized in that it uses the heat exchange system according to at least one of the claims from 1 to 12, comprising the following phases:
