Abstract

PROCEDIMIENTO PARA LA OBTENCION O RECUPERACION DE ACIDOS, EN PARTICULAR ACIDO CLORHIDRICO, ACIDO FLUORHIDRICO Y ACIDO NITRICO, A PARTIR DE SOLUCIONES DE ESTOS ACIDOS QUE CONTIENEN METALES, POR TRATAMIENTO PIROHIDROLITICO Y A CONTINUACION ABSORCION Y/O CONDENSACION DE LOS GASES FORMADOS EN UNA SOLUCION ACUOSA DE ABSORCION, RETIRANDO LOS COMPUESTOS SOLIDOS QUE APARECEN. PARA GARANTIZAR UNA RECUPERACION ECONOMICA DEL ACIDO, EN INSTALACIONES YA EXISTENTES Y SIN GRANDES MEDIDAS DE ADAPTACION, EL LIQUIDO RESIDUAL DE DECAPADO SE SOMETE A UNA PRECONCENTRACION POR EVAPORACION ANTES DE LA PIROHIDROLISIS UTILIZANDO EL CALOR DEL GAS DE SALIDA DE LA PIROHIDROLISIS. EN UN DISPOSITIVO PARA LA OBTENCION O RECUPERACION DE ACIDOS, EN PARTICULAR ACIDO CLORHIDRICO, ACIDO FLUORHIDRICO Y ACIDO NITRICO A PARTIR DE SOLUCIONES DE ESTOS ACIDOS QUE CONTIENEN METALES, COMPRENDIENDO UNA ENTRADA DE LA SOLUCION, UN REACTOR DE PIROHIDROLISIS, Y AL MENOS UNA COLUMNA DE ABSORCION O CONDENSACION, QUE ESTA UNIDA CON LA SALIDADE GAS DEL REACTOR, SE PREVE PARA LA PREEVAPORACION Y CONCENTRACION DE LA SOLUCION UNA INSTALACION 1, 3, 4; 31,32.
