13. Integração de processos em tempo real para monitoramento e controle : aplicação para planta de PET
This work deals with the implementation of a soft-sensor for a PET (Polyethylene terephtalate) industrial process based on neural networks. The soft-sensor acts as redundant measure current for the polymer viscosity in the liquid phase; and, in case of mechanical faults, it is able to diagnoses the faults on the viscometer and can replace it.The viscosity co

14. Desenvolvimento de uma instalação de separação de gases por adsorção e modelagem do processo
Separation processes account for the major production costs in chemical, petrochemical and related industries. Commercial pressure swing adsorption processes (the so-called PSA processes) have been intensively applied in industry since they need lower energy and are less costly than conventional separation processes for low to medium production rates. This w
