Abstract: A buffered multi-fluid heat exchanger and a buffered multi-fluid heat exchange process pertaining to the heat exchange equipment and process sector is disclosed. The heat exchanger (1) comprises a lower tubing or tube bundles (2) through which flows hot process fluid “Q” to be cooled; upper tubing or tube bundles (3) through which flows cold process fluid “F” to be heated, parallel to and spaced apart from the lower tubing (2); a vessel (4) for the tubing (2, 3) provided with inlet (2?) and outlet (2?) nozzles of the tubing (2), inlet (3?) and outlet (3?) nozzles of the tubing (3), and a portion of buffer fluid “T” that fills part of the vessel (4) that covers the lower tubing (2) through which circulates the hot process liquid “Q” to be cooled.

Abstract: A method and system for cooling sulfuric acid aqueous solutions (H2SO4) belonging to the field of chemical processes, which is part of a contact process for production of sulfuric acid with or without energy recovery. The method comprises absorption of SO3, which produces heated concentrated sulfuric acid and indirectly cooling the hot acid. The method uses a sulfuric acid-inert coolant. A cooling step comprises an intermediate indirect acid-fluid cooling and a second fluid-water or fluid indirect cooling step—third fluid, wherein when the process is of the type with energy recovery. A third step includes energy recovery, steam generation. A system to perform the method, which works next to the SO3 absorption tower comprises an acid cooling loop consisting of an intermediate acid-fluid heat exchanger; a second fluid-water heat exchanger, and when the process is of the type with energy recovery, said equipment further includes a steam generation boiler.
