Abstract

LOS GASES DE COMBUSTION DE LA SALIDA DE UN HORNO DE CALCINACION DE CAL (10) QUE CONTIENEN POLVO DEL HORNO DE CALCINACION DE CAL SE TRATAN PARA PRODUCIR UN PRECIPITADO DE CARBONATO CALCICO DE ALTA PUREZA. ESTO SE CONSIGUE HACIENDO PASAR LOS GASES DE COMBUSTION PROCEDENTES DEL HORNO DE CALCINACION DE CAL (10) A TRAVES DE UN SEPARADOR (12) DE POLVO EN EL HORNO DE CALCINACION, DE FORMA QUE EL POLVO DEL HORNO DE CALCINACION DE CAL QUE CONTIENE OXIDO CALCICO SE ELIMINA DEL GAS DE COMBUSTION REMANENTE (15). EL POLVO DEL HORNO DE CALCINACION DE LA CAL SE MEZCLA CON AGUA DE MANERA QUE SE FORMA UNA SUSPENSION ACUOSA DEL POLVO DEL HORNO DE CALCINACION DE CAL. LA CAL VIVA U OXIDO CALCICO EN EL POLVO DEL HORNO DE CALCINACION DE LA CAL SE HIDRATA PARA FORMAR HIDROXIDO CALCICO. SE DEJAN SEDIMENTAR LOS SOLIDOS DE LA SUSPENSION EN UN TANQUE DE SEDIMENTACION (14) DE FORMA QUE SE FORMA UNA SOLUCION CLARA SATURADA DE HIDROXIDO CALCICO QUE TIENE UN PH DE APROXIMADAMENTE 12,4. ESTA DISOLUCION A CONTINUACION SE PONE EN CONTACTO CON GAS DIOXIDO DE CARBONO EN UN TANQUE DE REACCION (16), DE FORMA QUE EL HIDROXIDO CALCICO REACCIONA FORMANDO UN PRECIPITADO DE CARBONATO CALCICO DE ALTA PUREZA. ESTE PRECIPITADO DE CARBONATO CALCICO DE ALTA PUREZA SE DEJA A CONTINUACION SEDIMENTAR DEL AGUA DEL SOBRENADANTE DE LA DISOLUCION EN UN TANQUE DE ESPESAMIENTO (20). EL CARBONATO CALCICO DE ALTA PUREZA SE SEPARA DEL AGUA DEL SOBRENADANTE, MIENTRAS QUE EL AGUA DEL SOBRENADANTE SE RECICLA A TRAVES DE UN CONDUCTO (24) Y SE USA COMO AGUA MEZCLADA CON EL POLVO DEL HORNO DE CALCINACION DE CAL FORMANDO UNA SUSPENSION ACUOSA.
