Abstract

Instalación de concentración de ácido fosfórico en circulación forzadas y bajo vacío, en la que la evaporación se realiza en dos etapas, para obtener, después de la segunda etapa, una concentración intermedio comprendida entre 38 y 48% de P2O5, pudiendo ser obtenida en un aparaato independiente la concentración final deseada de 54 o 65 % de P2O5, incluyendo esta instalación dos conjuntos de concentración, estando constituido cada uno de ellos por uno o varios cambiadores separadores, bombas de circulación, condensadores, cubetas de recogida, bombas de aspiración, purificadores de vapor y recalentadores.
