Abstract

La invención se relaciona a un proceso para la reducción de óxidos metálicos a material metalizado a través del contacto con gas reductor, en donde resulta un gas de tragante desempolvado en seco y que se somete a reformado en mezcla de gas crudo junto con hidrocarburos gaseosos. El contenido del vapor de agua del gas de tragante desempolvado en seco propuesto para la preparación de la mezcla de gas crudo será ajustado en un saturador en contracorriente por medio del agua de saturación, en donde se ajusta la temperatura del agua de saturación por mezclar agua fría con agua caliente, que tiene una temperatura superior al agua fría, con el fin de producir un valor objetivo del agua saturación. Un aparato para llevar a cabo ese proceso que tiene los conductos respectivos.
