Abstract

Procedimiento para tratar lodo formado durante la depuración de gas de instalaciones de altos hornos y acerías, particularmente durante la depuración de gases de tragante de altos hornos y que a continuación del proceso de depuración es sometido a espesamiento, caracterizado porque el lodo es sometido a una decantación y a continuación, en estado todavía fluyente, es provisto de un aditivo de carbono granular con capacidad de reducción, y porque esta mezcla es alimentada en un estado en que contiene todavía, aproximadamente, un 35 a un 55% en peso de H2O a un horno tubular giratorio, secada en éste a contracorriente de gas, *** ver imagen 01
