Exergetic and Economic Analysis of an Industrial Distillation Column
In this work, applications of exergy and economic concepts to compression, heat exchange, and separation processes were used for calculation of the irreversibility rate, thermodynamic efficiency, and internal rate of return (IRR) of the profitability. A case study based on a real process, the purification of 1,2dichloroethane (DCE) in a high-purity distillation column, is presented. This column...
متن کاملThe Advanced Process Control System for an Industrial Distillation Column
The control problem of an industrial distillation column is studied. Just the top control loop is discussed in this paper. By means of data collected from the distributed control system (DCS), two soft sensors are first developed. Based on this work, an inferential control project was proposed, and an optimization framework added on it, to improve control performance further. This advanced proc...
متن کاملSimulation and Control of an Aromatic Distillation Column
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...
متن کاملModeling and Control of an Industrial Distillation Plant Modeling and Control of an Industrial Distillation Plant
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...
