Abstract

"PROCESSO E SISTEMA PARA A CONCENTRAçãO DE SóLIDOS EM UMA SUSPENSãO LìQUIDA". Processo e equipamento para a concentração de suspensões pela remoção de líquido em uma unidade de um único efeito mantida sob vácuo para levar a efeito a vaporização instantânea do líquido a uma baixa temperatura. A unidade de um único efeito compreende uma única coluna de vaporização instantânea com circuitos de recirculação separados, um para pré-aquecer a suspensão que entra para concentração e um outro circuito separado para a retirada do suspensão concentrada. O vapor da coluna de vaporização instantânea pode ser tratado para separar o líquido dos outros componentes do vapor.
