Abstract

SE DESCRIBE UN PROCESO PARA EL TRATAMIENTO DE LICOR DE SULFURO CAUSTICO POR OXIDACION HUMEDA EN UN SISTEMA DE ALEACION BASADO EN HIERRO A TEMPERATURA MENOR DE ALREDEDOR DE 175 LICOR ES PRIMERO ANALIZADO POR ESPECIES QUE CONSUMEN ALCALINIDAD Y PARA ALCALINIDAD NO SULFURICA. SI ESPECIES QUE CONSUMEN EXCESO DE ALCALINIDAD ESTAN PRESENTES EN COMPARACION A LA ALCALINIDAD NO SULFURICA, ENTONCES LA ALCALINIDAD NO SULFURICA ADICIONAL SE AÑADE AL LICOR CRUDO TAL QUE EL EXCESO DE ALCALINIDAD ESTA PRESENTE DURANTE EL TRATAMIENTO DE OXIDACION HUMEDA, EVITANDO ASI EXCESO DE CORROSION AL SISTEMA DE ALEACION BASADA EN HIERRO
