The analysis of the history of structured packings allows the conclusion that the innovation cycle will become faster. Based on the separation power as an alternative way to represent the performance characteristics an estimate of the next level of what might be the ultimative separation power is given. Regarding the column internals like distributors only slight improvements are expected, typi...

A systematic computer aided analysis of the process model is used as a pre-solution step for integration of design and control problem. In this paper, a static energy integrated distillation plant model is first presented, then the analysis is presented for a single distillation column, subsequently the column analysis is extended with the analysis for the heat pump. The analysis relates to the...

Distillation is not only the most energy consumer but also the most frequently-adopted separation operation in chemical industries since it separates a mixture only by the difference among vapor pressures (boiling points) of components. So distillation is often called as the king of separation processes. Therefore, research and development of technologies on energy savings of distillation is an...

In general, the objective of distillation control is to maintain the desired products quality. In this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. These methods are: a) Composition control using measured composition directly. This method sufferes from large sampling delay of measuring de...

A batch reactor may be combined directly with a distillation column by distilling off the light component product in order to increase the reactor temperature or to improve the product yield of an equilibrium reaction. The same amount of the light product should be removed as the amount being formed by the reaction at any time. A linearized model has been developed which describes the process b...

This paper presents two integration approaches of real-time optimization (RTO) and adaptive model predictive control (MPC) in the 2-layer and 3-layer structures and their applications to the distillation column. The 2-layer structure is constructed based on the conventional hierarchical control layer. In the 3-layer structure, the quadratic programming (QP) layer is inserted to compute the feas...
