Abstract

"MéTODO PARA RECUPERAR áCIDO DE UMA MISTURA DE ALIMENTAçãO, E, MEMBRANA POLIMéRICA". Método para recuperar ácido de uma mistura de alimentação que compreende ácido, hidrocarbonetos e água, o método compreendendo: processar a dita mistura usando uma primeira membrana polimérica para formar um primeiro retido contendo uma concentração substancialmente maior de hidrocarbonetos que a dita mistura de alimentação e um primeiro permeado contendo uma concentração substancialmente maior de ácido e água que a dita mistura de alimentação, a dita primeira membrana polimérica sendo seletivamente permeável ao ácido e à água em relação aos hidrocarbonetos encontrados na mistura, e recuperar o primeiro permeado; o dito primeiro permeado pode ser processado ainda mais usando um segundo meio de redução de água para formar uma primeira corrente contendo uma concentração substancialmente maior de ácido que o dito primeiro permeado e uma segunda corrente contendo uma concentração substancialmente maior de água que o dito primeiro permeado, a dita etapa de redução de água podendo ser uma segunda membrana polimérica sendo seletivamente permeável à água em relação ao ácido no dito primeiro permeado; e recuperando a dita segunda corrente ou retido.
