Abstract

Process for the concentration of aqueous solutions and suspensions, by direct contact of these with a stream of hot gases, characterized in that the hot gases, having a temperature comprised between 70 and 1100º C, are sent to the bottom of a substantially vertical duct which is constituted by: 1) a lower part with an entrance zone for the gases; 2) a neck of decreasing section located in an upper position with respect to the gas inlet zone; 3) a part with an increasing cross section having a substantially truncated cone shape, located above the neck of decreasing section; in this neck of decreasing section the gases reach a speed comprised between 20 and 100 m/sec; the solution or suspension is introduced into the duct at the height of the neck of decreasing section so that it is subdivided into minute drops by means of the gaseous flow; these drops, while they begin to provide water to the gases, are lifted by this gaseous flow to a zone of the conduit in which the flow velocity is such that the droplets form a fluidized bed of substantially stable dimensions, in which the concentration of the solution or suspension; The concentrated drops of solution or suspension are entrained by the gaseous stream above the fluidized bed and, at the outlet of the conduit, are separated from the gases and collected by known means.
