Abstract
PROCESO DE EXTRACCION DEL DIOXIDO DE SULFURO CON PRODUCCION DE HIDROXIDO DE MAGNESIO Y YESO. SE EXTRAE EL DIOXIDO DE SULFURO DE LOS GASES DE COMBUSTION UTILIZANDO UNA SOLUCION ACUOSA DE COMPONENTES DE MAGNESIO EN UN DEPURADOR CON AGUA (1), CON OXIDACION DE UNA PARTE DE LA DESCARGA ACUOSA DEL DEPURADOR. SE AÑADE SULFATO DE CALCIO (25) A LA PARTE DE DESCARGA ACUOSA EN EL OXIDANTE (17) PARA FORMAR UN EFLUENTE ACUOSO OXIDIZADO QUE CONTIENE SOLIDOS DE SULFATO DE CALCIO Y SULFATO DE MAGNESIO DISUELTO. EL EFLUENTE ACUOSO OXIDIZADO SE REGENERA POR ADICION DE CAL, EN UN DEPOSITO DE REGENERACION (31), QUE PRECIPITA EL SULFATO DE CALCIO COMO YESO, CON YESO (43) DEVUELTO AL OXIDANTE COMO SULFATO DE CALCIO AÑADIDO AL MISMO. PREFERIBLEMENTE, SE DIVIDE LA DESCARGA ACUOSA DEL OXIDANTE (17), CON UNA PARTE PRINCIPAL QUE PASA AL SEPARADOR (59) PARA EXTRAER EL YESO DEL MISMO, MIENTRAS QUE UNA PARTE MENOR SE PASA AL DEPOSITO DE REGENERACION (31). TAMBIEN SE PUEDE INTRODUCIR LA SOLUCION DE SULFATO DE MAGNESIO (63), TRAS LA SEPARACION DEL YESO (61) DE LA PARTE PRINCIPAL EN EL DEPOSITO DE REGENERACION (31).
