Abstract
SE PRESENTA UN PROCEDIMIENTO HUMEDO DE TIPO REGENERATIVO PARA ELIMINAR EL SO{SUB,2} PRESENTE EN LOS GASES DE COMBUSTION, QUE SE CARACTERIZA PORQUE HACE QUE UNA SOLUCION ACUOSA DILUIDA DE BAS ABSORBA EL SO{SUB,2}, Y LAS REACCIONES CONSIGUIENTES FORMAN UN PRECIPITADO MIXTO DE S ELEMENTAL, BASO{SUB,3} Y BASO{SUB,4}. EL AZUFRE SE RETIRA DEL PRECIPITADO -RECUPERADO POR FILTRACIONUTILIZANDO UNA SOLUCION DE (NH{SUB,4}){SUB,2}S; SE DESTILA EL POLISULFURO RESULTANTE, CON LO QUE SE OBTIENE S PURO ELEMENTAL Y LA SOLUCION DE (NH{SUB,4}){SUB,2}S A RECICLAR. LA MEZCLA RESIDUAL DE BASO{SUB,3} Y DE BASO{SUB,4} QUE PERMANECE DESPUES DE LA EXTRACCION DEL AZUFRE SE REDUCE CON HULLA EN UN HORNO DE ALTA TEMPERATURA, PARA OBTENER BAS A RECICLAR, A MODO DE SOLUCION ACUOSA, PARA EL PASO DE ABSORCION DE SO{SUB,2}.
