Abstract

UN PROCEDIMIENTO PARA LA OBTENCION DE ACIDO FLUORHIDRICO. CONSISTE EN EFECTUAR UN TRATAMIENTO PIROHIDROLITICO DE MATERIALES QUE CONTENGAN FLUOR EN UNA CAPA FLUIDIZADA EXPANDIDA CON POSTERIOR ENFRIAMIENTO DE LOS GASES DE ESCAPE. EL ENFRIAMIENTO DIRECTO SE EFECTUA JUNTANDO LAS MATERIAS SOLIDAS REFRIGERADAS Y EL GAS DE ESCAPE EN UN INTERCAMBIADOR DE CALOR DE MATERIAL SUSPENDIDO. LAS PARTES SOLIDAS SE VUELVEN A REFRIGERAR EN UN REFRIGERADOR DE LECHO FLUIDIZADO, PREFERENTEMENTE EN VARIAS ETAPAS. A LA CAPA FLUIDIZADA LE SON ALIMENTADOS LOS GASES OXIGENADOS EN DOS CORRIENTES PARCIALES A DIFERENTE ALTURA. LAS MATERIAS SOLIDAS DESCARGADAS CON EL GAS DE ESCAPE, UNA VEZ SEPARADAS, SE DEVUELVEN A LA ZONA INFERIOR DE LA CAPA FLUIDIZADA. I
