Abstract

PROCEDIMIENTO PARA LA DESULFURACION CONTINUA DE GASES DE COMBUSTION DEL TIPO DENOMINADO DE ALCALI DE SODIO-PIEDRA CALIZA.COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, SE ABSORBE DIOXIDO DE AZUFRE A PARTIR DE UNA CORRIENTE GASEOSA QUE CONTIENE SO2, MEDIANTE UN ABSORBEDOR QUE CONTIENE UNA SOLUCION ACUOSA DE SULFITO SODICO Y BISULFITO SODICO; SEGUNDA, SE DESVIA UNA PORCION DE LA SOLUCION EFLUENTE DEL ABSORBEDOR PARA LA REGENERACION CON PIEDRA CALIZA; TERCERA, SE INTRODUCE PIEDRA CALIZA EN LA SOLUCION DESVIADA PARA CONVERTIR BISULFITO A SULFITO; Y POR ULTIMO, SE SEPARAN LOS SOLIDOS SUBPRODUCTOS DE LA SOLUCION TRATADA Y SE RETORNA LA SOLUCION REGENERADA AL ABSORBEDOR.
