Abstract

PROCESSO, E, PROCESSO PARA RECUPERAR CATALISADOR DE METAL DE UMA CORRENTE DE PURGA DE OXIDADOR. é divulgado um processo que está relacionado à recuperação de um catalisador de metal de uma corrente de purga de oxidador produzida na síntese de um ácido carboxílico, tipicamente o ácido tereftálico. Mais particularmente, o processo envolve a recuperação de um catalisador de metal de uma corrente de purga de oxidador através do uso de um filtro sob pressão, a combinação de água com um líquido mãe para recuperar o catalisador de metal, submetendo em seguida a mistura aquosa assim formada a uma extração em estágio único, com um solvente de extração, para produzir um a corrente de extrato compreendendo impurezas orgânicas e uma corrente de refinado compreendendo o catalisador de metal.
