Abstract

PROCESSO PARA SEPARAR ANIDRIDO MALEICO DE UMA CORRENTE GASOSA CONTENDO ANIDRIDO MALEICO. A invenção refere-se a um método para separar anidrido maleico de uma corrente gasosa contendo anidrido maleico. De acordo com o citado método: a) o fluxo de gás contendo anidrido maleico é contatado com uma fase absorvente líquida contendo pelo menos um agente de absorção inerte de alto ponto de ebulição para anidrido maleico, e b) anidrido maleico é separado da fase líquida de absorbato por extração em uma coluna usando gás hidrogênio como agente de extração. A invenção é caracterizada pelo fato de que o agente de extração é fornecido à coluna em dois pontos separados por pelo menos um estágio de separação teórico.
