Previous issue date: 2009-06-29 / The petrochemical industry has as objective obtain, from crude oil, some products with a higher commercial value and a bigger industrial utility for energy purposes. These industrial processes are complex, commonly operating with large production volume and in restricted operation conditions. The operation control in optimized and stable conditions is important to keep obtained products quality and the industrial plant safety. Currently, industrial network has been attained evidence when there is a need to make the process control in a distributed way. The Foundation Fieldbus protocol for industrial network, for its interoperability feature and its user interface organized in simple configuration blocks, has great notoriety among industrial automation network group. This present work puts together some benefits brought by industrial network technology to petrochemical industrial processes inherent complexity. For this, a dynamic reconfiguration system for intelligent strategies (artificial neural networks, for example) based on the protocol user application layer is proposed which might allow different applications use in a particular process, without operators intervention and with necessary guarantees for the proper plant functioning / A ind?stria petroqu?mica tem por objetivo obter, a partir do petr?leo bruto, produtos de alto valor comercial e de maior utilidade industrial para fins energ?ticos. Os processos dessa ind?stria s?o complexos, geralmente operam com grandes volumes de produ??o e em condi??es restritas de opera??o. O controle da opera??o em condi??es ?timas e est?veis ? importante para manter a qualidade dos produtos obtidos e a seguran?a da planta. Atualmente, as redes industriais t?m alcan?ado destaque quando h? a necessidade de se realizar o controle do processo de forma distribu?da. O protocolo para redes industriais Foundation Fieldbus, por sua caracter?stica de interoperabilidade e sua interface com usu?rio organizada em blocos de simples configura??o, tem grande notoriedade dentre o grupo de redes para automa??o industrial. O presente trabalho agrega os benef?cios trazidos pela tecnologia de redes industriais ? complexidade inerente dos processos ligados a industria petroqu?mica. Para tal, ? proposto um sistema para reconfigura??o din?mica de estrat?gias inteligentes (redes neurais artificiais, por exemplo) baseado na camada de aplica??o do usu?rio do protocolo, o qual poder? permitir o uso de diferentes aplica??es em um determinado processo, sem
interven??es de operadores e com as garantias necess?rias para o bom funcionamento da planta
