Immiscible, direct contact, floating bed enhanced, liquid/liquid heat transfer process

摘要

A heat transfer process for a liquid (5) using counterflow, direct contact with another, immiscible fluid (1), of differing temperature and density, in the presence of a free floating media bed (7). Heat transfer within the liquid (5) occurring as a consequence of direct contact with the immiscible fluid (1) of differing temperature. The counterflow motion a consequence of buoyancy forces resulting from the different densities of the liquid (5) and immiscible fluid (1). The media bed (7) being of a nature preferentially wetted by the immiscible fluid (1), thereby providing a large film type surface area of the immiscible fluid (1) for direct contact heat transfer with the liquid (5). The free floating nature of the media bed (7) resulting from the materials comprising the media being of a density intermediate between that of the liquid (5) and that of the immiscible fluid (1). The free floating media bed (7) being by nature nonplugging and providing enhanced direct contact heat transfer by the extended fluid film surfaces confined therein.
