Abstract

"CONTROLE DE PROCESSO NA PRODUçãO DE áCIDO ACéTICO VIA O USO DA MEDIçãO DA DENSIDADE DA FASE PESADA". A presente invenção refere-se a um processo para monitoramento e controle das condições do reator durante a produção de ácido acético por carbonilação catalizada de metanol. O processo da presente invenção compreende a medida da densidade da fase pesada dos finais leves da coluna de destilação no sistema de purificação do processo de carbonilação. A medida da densidade é usada para ajustar a alimentação de metanol e/ou regular a temperatura na zona de reação para otimizar as condições do reator. A medida da densidade pode também ser usada para ajustar outros parâmetros no sistema do reator. A invenção está também direcionada ao sistema de fabricação de ácido acético baseado no procedimento de controle de processo descrito.
