چکیده
this paper deals with optimal operation of a three-product dividing-wall column (dwc). the main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. exact local method is used to find the best controlled variables as single measurement or combination of measurements based on the idea of self-optimizing control. it concluded that it is possible to have better self-optimizing properties by controlling linear combinations of measurements than by controlling conventional individual measurements. dynamic validation showed that the proposed control structure with the aid of low-complexity simple pi controller stabilized the plant, rejected the effect of disturbances and made dwc to produce product with desired specifications.

متن کاملOptimal Operation of a DWC by Self-Optimizing Control: Active Vapor Split Approach
Dividing Wall Column(DWC) offers the large potential for operating and capital cost saving in compared with conventional distillation sequence. In the studied DWC in this study, the aid of Vmin diagrams, it is shown that without a suitable value for vapor split fraction bellow the dividing wall in different operating conditions, the energy requirement increases from optimal value and it wil...
متن کاملOptimal Design Methodology for Dividing Wall Columns
The dividing wall column, DWC, is a thermally coupled sequence that can perform the separation of fluid mixtures with reduced energy consumption, but also decreasing the capital costs associated. Several authors have developed design procedures for this kind of sequence, using short methodologies or optimization strategies. The use of short procedures is easy and fast, but, in the most of the c...
متن کاملMulti Objective Optimisation for an Economical Dividing Wall Column Design
The dividing wall column is experiencing a growing interest in industry. The concern about difficult controllability vanishes further and this leads to growing demand of approved guidelines for the design which is indeed time consuming if no expert knowledge is available. In this contribution the design task of a dividing wall column is treated as multi objective optimisation. Backbone of this ...
متن کاملOn A New Approach for Self-optimizing Control Structure Design
In this paper, a new method for the identification of self-optimizing control structure designs (CSDs) based on generalized singular value decomposition (GSVD) is proposed. The method is primarily dedicated to find optimal CSDs where all controlled variables (CVs) are represented by a common set of linear combinations of process variables (PVs). It is shown that the implementation of the GSVD i...
متن کاملControl structure design for optimal operation of heat exchanger networks
When only single bypasses and utility duties are used as manipulations, optimal operation of heat exchanger networks (HENs) can be categorized as an active constraint control problem. This work suggests a simple split-range control scheme to implement the optimal operation. The control structure can be found by solving an integer-linear programming (ILP) problem with two objective functions pro...
