Abstract

SE PROVEE UN PROCESO PARA PRODUCIR SULFATO DE POTASIO A PARTIR DE CLORURO DE POTASIO Y ÁCIDO SULFÚRICO. EL PROCESO COMPRENDE MEZCLAR CLORURO DE POTASIO CON AGUA PARA FORMAR UNA SUSPENSIÓN QUE SE MEZCLA CON EL ÁCIDO SULFÚRICO RECICLADO PARA FORMAR UNA MEZCLA DE ÁCIDO K+ , CL- , SO4 2- . ESTA MEZCLA SE SOMETE A UN PROCESO DE CRISTALIZACIÓN QUE PRODUCE CRISTALES DE SULFURO DE POTASIO Y VAPOR DE AGUA-ÁCIDO CLORHÍDRICO. EL ÁCIDO CLORHÍDRICO SE SEPARA PARA FORMAR UNA SOLUCIÓN DE ÁCIDO CLORHÍDRICO.
