Abstract

EL PROCESO DE TRATAMIENTO DE UN ACIDO CLORHIDRICO RESIDUAL O ACIDO BRUTO CONTAMINADO CON FLUOR CONSISTE EN UNA RECTIFICACION DESHIDROGENANTE UTILIZANDO UN AGENTE DE ARRASTRE EN CIRCUITO CERRADO, EN EL CUAL CIRCULA UNA SOLUCION ACUOSA DE SUSTANCIAS FIJADORAS DE AGUA Y DE FLUORURO. EL AGENTE DE ARRASTRE CONTIENE UN PRECIPITANTE QUE PERMITE SEPARAR EL FLUOR Y EL SILICIO COMO PRODUCTOS SOLIDOS EN FORMA DE LODO.
