Abstract

MÉTODO PARA REMOVER ÁCIDO ACÉTICO DE UMA CORRENTE DE ÁGUA DE REFUGO - A presente invenção provê um método para remoção de compostos orgânicos, tal como ácido acético, de correntes de água de refugo em processos para a produção de ácido (met)acrílico. Em particular, um gás produto misto, compreendendo ácido (met)acrílico, ácido acético, propileno e acroleína, é submetido a absorção fracionária para produzir uma corrente de produto aquoso compreendendo ácido (met)acrílico, água e ácido acético, e uma corrente de gás residual do absorvedor compreendendo propileno e acroleína. A corrente de produto aquoso é destilada para produzir uma corrente de ácido (met)acrílico purificando e uma corrente de água de refugo compreendendo água e ácido acético. O gás residual do absorvedor é em seguida colocado em contato com a corrente de água de refugo e pelo menos uma porção de ácido acético se move da corrente de água de refugo para gás residual do absorvedor para produzir uma corrente de água de refugo extraída e um gás residual do absorvedor enriquecido.
