Claim:
1. A heat exchange system comprising: a single apparatus having an area immersed in a fluid bath and a free space at the apparatus head in which a vapour phase is accumulated, at least one interspace open at both ends, situated inside said apparatus and completely immersed in the fluid bath, one or more heat exchange surface(s) which yield heat to one or more flows of cold material, one or more heat exchange surface(s) which absorb heat from one or more flows of hot material, at least an inlet gate for the one or more flows of cold material coming from an external cold source and at least an inlet gate for the one or more flows of hot material coming from an external hot source, at least an outlet gate for at least a flow of cooled material and at least an outlet gate for at least a flow of heated material by means of said heat exchange surfaces, wherein: said system contains all the heat exchange surfaces in the single apparatus, said heat exchange 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 material, the heat exchange surface(s) which yield heat to the one or more flows of cold material are situated inside the interspace and the heat exchange surface(s) which absorb heat from the one or more flows of hot material are situated in the space between said interspace and the walls of the apparatus, and the external hot sources and the cold sources are hot material and cold material generated in the production process of hydrogen or synthesis gas, or both.
