Abstract

Los componentes de la sal de las granzas pueden extraerse de manera eficiente a través de la evaporación. Durante el tratamiento de las granzas, puede permitirse que las temperaturas se aproximen o excedan el punto de ebullición de uno o más componentes de la sal de las granzas, de manera preferida, en un medio oxidante. La temperatura puede mantenerse suficientemente alta, de manera que el contenido de sal pueda ejercer una presión de vapor apreciable y pueda mantenerse durante un tiempo suficiente para permitir que la mayoría, todo o sustancialmente todo el contenido de sal se evapore y se transporte lejos del horno en los gases de combustión. La sal evaporada puede condensarse y recolectarse.
