FIELD: gas industry.
SUBSTANCE: invention relates to a saturator for addition of water vapour to gas and a natural gas reforming system equipped with such a saturator. Saturator contains a flowpath through which the first fluid medium flows, the first heat exchange unit, which causes heat exchange between the first fluid medium and the second fluid medium, the second heat exchange unit, which causes heat exchange between the third fluid medium and the first fluid medium, after the first fluid medium passes through the first heat exchanger - a wetting unit for adding water to the first fluid medium, which flows along the flowpath on the sides above the first fluid medium from the first heat exchange unit and the second heat exchange unit, and a transfer line for transportation of the third fluid medium after the heat exchange in the second heat exchange unit from the second heat exchange unit onto the flowpath side above of the first fluid medium from the first heat exchange unit, so that the third fluid medium flows along the flowpath as the first fluid medium. Herewith in the first heat exchange unit the first fluid medium is heated and wetted, and the second fluid medium is cooled and delivered outside the system, while in the second heat exchange unit the first fluid medium is heated and wetted up to the pressure of saturated steam and delivered outside the system, and the third fluid medium is cooled.
EFFECT: invention increases efficiency of recycling and utilisation of heat from a heat source, which increases thermal efficiency.
