Abstract

Procedure for the concentration of phosphoric acid in forced circulation and under vacuum, characterized in that the evaporation is carried out in two stages, to obtain, after the second stage, an intermediate concentration of between 38 and 48% of P2O5, which can be obtained in a independent apparatus the desired final concentration of 54 or 65% P2O5.
