Abstract

SE HAN DESCUBIERTO UN METODO Y UN APARATO PARA LIMPIAR GASES QUE CONTIENEN DIOXIDO DE SULFURO, COMO GASES DE CHIMENEAS. LOS GASES SON TRATADOS EN UN LAVADOR DE GASES (2) PARA LA ABSORCION DE DIOXIDO DE SULFURO LIQUIDO DETERGENTE ALCALINO ACUOSO (3), PREFERIBLEMENTE NAOH. UNA PARTE DEL FLUJO (10) ES SEPARADA DEL LIQUIDO DETERGENTE PARA SER REGENERADA MEDIANTE LA ADICION DE IONES DE CALCIO (17) PARA LA PRECIPITACION Y ELIMINACION DE SULFATO DE CALCIO. EL INVENTO SE DISTINGUE POR EL HECHO DE QUE EL SULFATO DE CALCIO PRECIPITADO ES RECICLADO Y MEZCLADO (14) CON PARTE DEL FLUJO DEL LIQUIDO DETERGENTE ANTES DE LA ADICION DE LOS IONES DE CALCIO. EL APARATO COMPRENDE UN LAVADOR DE GASES (2) QUE TIENE MECANISMOS (5,6,7,9) PARA LA CIRCULACION DEL LIQUIDO DETERGENTE (3), UN CONDUCTO (11) PARA SEPARAR UNA PARTE DEL FLUJO (10) DE LIQUIDO DETERGENTE, UN VASO (16) PARA LA ADICION DE IONES DE CALCIO (17), UN VASO (18) PARA LA SEDIMENTACION DEL SULFATO DE CALCIO PRECIPITADO, UN VASO (22) PARA LA ADICION DEIONES DE CARBONATO, UN VASO (24) PARA LA SEDIMENTACION DEL CARBONATO DE CALCIO, UN CONDUCTO (26) PARA RECICLAR EL LIQUIDO DETERGENTE REGENERADO EN EL LAVADOR DE GASES (2), Y UN CONDUCTO (25) PARA RECICLAR EL CARBONATO DE CALCIO PRECIPITADO MAS ARRIBA DEL VASO (18) PARA LA SEDIMENTACION DEL SULFATO DE CALCIO. EL APARATO SE DISTINGUE POR ESTAR DOTADO DE UN CONDUCTO (19) DESTINADO A RECICLAR EL SULFATO DE CALCIO PRECIPITADO QUE SE ABRE DENTRO DEL VASO (14) QUE ESTA SITUADO MAS ARRIBA DEL VASO (16) PARA LA ADICION DE IONES DE CALCIO.
