Abstract
"MéTODO DE CONTROLE EM LINHA DE UMA PLANTA, DE POLIMERIZAçãO, SISTEMA DE CONTROLE, E, PROCESSO PARA A PRODUçãO DE POLIPROPILENO E SEUS COPOLìMEROS". é descrito um método para controle em linha, de propriedades físicas e químicas de polipropileno e seus copolímeros. O método compreende modelos para a inferência de propriedades físicas e químicas que não são medidas continuamente e modelos para o controle dessas propriedades, bem como a taxa de produção, densidade do meio de reação e de outras variáveis do processo de interesse. O sistema de controle descrito permite a maximização da taxa de produção bem como do rendimento do catalisador no processo produtivo."METHOD OF ON-LINE CONTROL OF A PLANT, POLYMERIZATION, CONTROL SYSTEM, AND, PROCESS FOR THE PRODUCTION OF POLYPROPYLENE AND ITS COPOLYMERS". a method for inline control of physical and chemical properties of polypropylene and its copolymers is described. The method comprises models for the inference of physical and chemical properties that are not measured continuously and models for the control of these properties, as well as the production rate, density of the reaction medium and other variables of the process of interest. The described control system allows the maximization of the production rate as well as the catalyst yield in the production process.
