Abstract

"MéTODO PARA A OPERAçãO SEGURA DE UM PROCESSO DE REAçãO QUìMICA". A parada não rotineira (por exemplo, de emergência) de um processo de reação química é executada por um método para operação segura de um processo de reação química, que compreende as etapas de detecção de uma condição indesejável capaz de afetar o processo, minimizando a reação dos reagentes, e mantendo um fluxo de materiais através das zonas de reação do processo, de tal forma que a mistura da reação seja deslocada das zonas de reação. O fluxo de materiais poderá ser mantido durante um período de tempo tal que substancialmente toda a mistura da reação é deslocada das zonas de reação, dessa forma lavando as zonas de reação. A mistura da reação poderá então ser purgada para um vaso auxiliar, como um absorvedor.
