The main objective in refining units is to keep the product quality within specifications in the faces of disturbances. Online measurements of product composition using composition analyser are neither easy nor economically viable. In an effort to overcome these difficulties various soft sensors are designed in the recent years. In this research work, the authors have proposed the design of neu...

M and control of distillation columns is a research area that evokes considerable interest. On the one hand, substantial savings are possible with good controllers, on the other hand, distillation columns are often used as test cases for new methods of model based controller design. Strongly nonlinear behavior and high order are the characteristics that present challenges when designing control...

Molecular diffusion is an omnipresent phenomena that is important in a wide variety of contexts in chemical, physical, and biological processes. In the majority of cases, the diffusion process can be adequately described by Fick's law that postulates a linear relationship between the flux of any species and its own concentration gradient. Most commonly, a component diffuses down the concentrati...
