Abstract

"CONTROLADOR DE SISTEMA DE MEMBRANA, SISTEMA DE MEMBRANA PERMEáVEL, E, PROCESSOS DE CONTROLE DE UM SISTEMA DE MEMBRANA PERMEáVEL, E DE CONTROLE DO NìVEL DE PUREZA DE PELO MENOS UM PRODUTO GASOSO SEPARADO DE UMA MISTURA GASOSA". Processo de controle e controlador de sistema de membrana para maximizar a produção de produto retentato e incorporar meio de detecção de carga de compressor e instrumentação de parâmetro de processo para alimentar uma unidade controladora com informação essencial de monitoração. Maximização de produção de produto é acompanhada pelo aumento de temperatura de operação da membrana durante períodos quando a capacidade do compressor está sub-utilizada.
