Abstract
"PROCESSO CONTìNUO PARA PREPARAR áCIDO LáCTICO, SOLUçãO DE áCIDO LáCTICO CONCENTRADA EM áGUA , áCIDO LáCTICO, E, USO DE SULFATO DE CáLCIO". A invenção refere-se a um processo continuo para preparar ácido láctico, que compreende: (a) acidificar uma alimentação aquosa, que foi obtida por fermentação e contém principalmente lactato, com uma corrente contendo ácido inorgânico, a um pH de 1 a 4, para formar uma corrente aquosa, que consiste principalmente de ácido láctico e de um sal, (b) remover o sal a partir da corrente aquosa, que contém principalmente ácido láctico e sal, para formar uma primeira corrente aquosa, que contém principalmente ácido láctico, (c) passar a primeira corrente aquosa, que contém principalmente ácido láctico, através de uma coluna contendo carvão ativado para formar uma segunda corrente aquosa, que contém principalmente ácido láctico, (d) submeter a segunda corrente aquosa, que contém principalmente ácido láctico a um primeiro estágio de extração, em que a segunda corrente aquosa, que contém principalmente ácido láctico, é colocada em contato com uma corrente substancialmente insolúvel em água, que contém um extractante, para formar uma fase orgânica, que contem principalmente ácido láctico e extractante e uma primeira fase aquosa, que contém principalmente impurezas, (e) submeter a fase orgânica, que contém principalmente ácido láctico e um extractante a um segundo estágio de extração, em que a fase orgânica, que contém principalmente ácido láctico e o extractante é colocada em contato com uma corrente aquosa para formar uma fase aquosa, que contém principalmente ácido láctico e uma fase orgânica, que contém extractante, em que a fase orgânica, que contém extractante, é reciclada ao estágio (d), e (f) concentrar a fase aquosa, que contém principalmente ácido láctico, através de evaporação da água para formar uma solução de ácido láctico concentrada em água.
