Abstract

"PROCESSO PARA CONTROLAR UM PROCESSO EXOTéRMICO EM FASE GASOSA CONTìNUO EM UM REATOR". Um processo para controlar um processo exotérmico em fase gasosa contínuo em um reator compreendendo: (i) efetuar uma reação exotérmica em fase gasosa sob um conjunto de condições operacionais na presença de um agente de resfriamento, o agente de resfriamento tendo uma concentração pré-selecionada e uma taxa de alimentação de um agente de resfriamento induzido; (ii) determinar uma taxa máxima de produção (I) sem relação às limitações devidas ao agente de resfriamento sob as condições operacionais; (iii ) determinar uma taxa máxima de produção (II) com relação às limitações devidas ao agente de resfriamento sob as condições operacionais; (iv) calcular uma concentração ótima do agente de resfriamento induzido tal que a diferença entre (I) e (II) seja minimizada; e (v) ajustar a taxa de alimentação do agente de resfriamento induzido para alcançar o valor da concentração calculado em (iv).
