Abstract

REMOçãO DE COMPOSTOS REDUTORES DE PERMANGANATO DA CORRENTE DO PROCESSO DE CARBONILAçãO DE METANOL é apresentado um aperfeiçoamento do processo de carbonilação de metanol para fabricação de ácido acético. é especificamente apresentado um método para remoção de compostos redutores de permanganato ("PRC's") da corrente de suspensão de terminais leves condensados, que inclui (a) destilar pelo menos uma porção da suspensão de terminais leves condensados para produzir uma segunda corrente de suspensão enriquecida com PRC; (b) extrair a segunda corrente de suspensão com água e separar daquela uma corrente aquosa que contém PRC's e (c) retornar pelo menos uma porção da segunda suspensão extraída para o segundo destilador.
