Abstract

"ESTRATéGIAS DE CONTROLE AVANçADO PARA PROCESSOS DE GERAçãO DE DIóXIDO DE CLORO". Processos de geração de dióxido de cloro do tipo de recipiente único que produzem dióxido de cloro de alta pureza são monitorados e controlados por um computador usando-se estratégias de controle avançado para operação estável, constante, com uso químico ótimo e com base em uma taxa de produção de dióxido de cloro desejada como a única entrada a partir de um operador para o programa de computador efetuando o controle por computador.
