Abstract

MÉTODO E APARELHO DE PURIFICAÇÃO DE UMA CORRENTE DE PROCESSO BAYER. A presente invenção refere-se a um aparelho e a um método para purificar uma corrente de processo Bayer que inclui um estágio FILTRAR, que compreende pelo menos um filtro configurado para filtrar material particulado de pelo menos uma corrente de líquido iônico dos estágios EXTRAIR, SEPARAR e REGENERAR. A filtração do material particulado de pelo menos uma das correntes de líquido iônico reduz as quantidades de material particulado circulante e reduz o potencial de formação de resíduo.
