Abstract

UN PROCESO DE DESULFURIZACION DE GASES DE COMBUSTION HUMEDOS EN EL QUE UN DIOXIDO DE SULFURO PRESENTE EN LOS GASES DE COMBUSTION ES ABSORBIDO EN UN LODO QUE CONTIENE UN COMPUESTO DE CALCIO; EL LODO QUE TIENE DIOXIDO DE SULFURO ABSORBIDO EN EL MISMO, ES DIOXIDIZADO PARA FORMAR UN LODO DE YESO, Y EL YESO ES SEPARADO Y RECUPERADO DEL LODO, QUE CONSTA DE LOS PASOS DE SUMERGIR UNA PARTE DE LA SUPERFICIE DE FILTRO CIRCULANTE DE UN FILTRO DE SUCCION EN EL LODO DE YESO PARA CAUSAR QUE EL YESO SE ADHIERA A LA SUPERFICIE DE FILTRO, PORTANDO LA SUPERFICIE DE FILTRO QUE SOPORTA EL YESO POR ENCIMA DE LA SUPERFICIE DEL LODO DE YESO, Y SUCCIONANDO LA FASE LIQUIDA A TRAVES DE LA SUPERFICIE DE FILTRO PARA FORMAR UNA CAPA DE YESO DESHIDRATADA, Y EXTRAER LA CAPA DE YESO DE LA SUPERFICIE DE FILTRO, ADEMAS DE UN APARATO PARA LLEVAR A CABO ESTE PROCESO.
