Title: HEAT EXCHANGING METHOD WITH A TWO-PHASE LIQUID/SOLID HEAT-TRANSFER FLUID
Abstract:
The invention concerns a heat exchanging method generating a solid phase in a two-phase liquid/solid fluid (D), by direct contact of the two-phase fluid (D) and a heat transfer fluid (T), both fluids being immiscible and having different densities, the transfer fluid (T) remaining liquid during the heat transfer coming from the two-phase fluid (D) which is partially solidified when cooling, the solid part of the two-phase fluid having a density different from that of the liquid part. The invention is characterised in that it comprises steps which consists in: mixing the two-phase fluid (D) and the heat transfer fluid (T), in a zone of strong turbulent flow (Z1); circulating, and separating into two layers by difference of density the two-phase fluid (D) from the transfer fluid (T) circulating in a flowing zone (Z2), the speed of the two-phase fluid being greater than the decantation speed of its solid phase.
