Abstract

remoção de sais de amina estáveis ao calor a partir de correntes líquidas e processos relacionados. propõem-se processos para remoção dos sais de amina estáveis ao calor de uma solução de amina aquosa contaminada compreendendo passar uma corrente de alimentação da solução de amina aquosa contaminada em uma zona de eletrodiálise compreendendo pelo menos uma unidade de repetição com um compartimento de solução de amina para receber a corrente de alimentação, um compartimento de resíduos e um compartimento de fonte de ânions que recebe uma corrente de fonte de ânions ou uma membrana bipolar disposta para fornecer ânions que equilibram os ânions estáveis ao calor. o monitoramento de um parâmetro relacionado à fonte de ânions, que está correlacionado à concentração da fonte de ânions da corrente de fonte depletada de ânions, ou de um parâmetro de resíduo, que está correlacionado a uma concentração de ácido da corrente de resíduos, é realizado para ajustar ainda mais uma adição da fonte de ânions ou uma remoção da corrente de resíduos de acordo com o parâmetro monitorado.
