A method for deriving reduced dynamic models of one-dimensional distributed systems is presented. It inherits the concepts of the aggregated modeling method of Lévine and Rouchon originally derived for simple staged distillation models and can be applied to both spatially discrete and continuous systems. The method is based on partitioning the system into intervals of steady-state systems, whic...

Batch and continuous systems are of multivariable in nature. A multivariable system is one in which one input not only affects its own outputs but also one or more other outputs in the plant. Multivariable processes are difficult to control due to the presence of the interactions. Increase in complexity and interactions between inputs and outputs yield degraded process behavior. Such processes ...

Hybrid separation systems have recently been hailed as one of the inost promising alternatives to conventional capital and energy intensive separation processes. Hybrid separation systems are able to effectively separate inixtures commonly encountered in the fine chemical and pharmaceutical industries that are difficult or impossible to separate by conventional distillation processes due to aze...

Biodiesel is touted to be an alternative the fossil fuels as it conducive environment. This investigation proposes a control framework produce biodiesel in reactive distillation column via transesterification process. To extract quality product, temperature profile must maintained along per requirements. However, constant interactions among products inside disturb and consequently product quali...

Monoethanolamine is an essential chemical used as feedstock in the production of detergents, emulsifiers, pharmaceuticals, polishes, corrosion inhibitors, and intermediates. It produced industrially by treating ethylene oxide with aqueous ammonia, but reaction also leads to di- tri-ethanolamine less desired by-products. This study first propose intensified process for ethanolamines combining re...
