PROCESS FOR THE THERMAL AND/OR CHEMICAL HOMOGENEOUS TREATMENT OF A FLUID, AND APPLICATION TO SYNTHETIC INORGANIC PHOSPHATES

摘要

1. A process for thermal treatment of a fluid dispersible phase such as in particular a liquid, semi-liquid or powder phase, by a dispersant gaseous phase, characterised in that, successively and without a break, by the action of the gaseous phase : a) the dispersible phase is transformed into a dispersion of elementary volumes such as fine solid or liquid particles which are substantially equally distributed in said gaseous phase so as to provide for systematically homogeneous mixing of the two dispersible and dispersant phases ; b) said dispersion is subjected by heat exchange by means of the dispersant phase to a thermal flash treatment in a plug-type flow zone ; c) in a zone having a flow which is homogeneous in the sense of the distribution of the residence times, the dispersion from zone b is subjected to a substantially isothermal treatment in chemically homogeneous gaseous phase.
