“…The employed solution strategy is based on the targeted reverse design approach and employs thermodynamic-process insights, for example, the attainable region 16 and the driving force concept 17 , to decompose the integrated design-control problem into four sequential hierarchical sub-problems 10 . Based on the solution of the decomposed set of hierarchical sub-problems, large number of infeasible solutions within the search space are identified and eliminated.…”

In this work, integrated process design and control of reactive distillation processes is considered through a computer-aided framework. First, a set of simple design methods for reactive distillation column that are similar in concept to non-reactive distillation design methods are extended to designcontrol of reactive distillation columns. These methods are based on the element concept where the reacting system of compounds is represented as elements. When only two elements are needed to represent the reacting system of more than two compounds, a binary element system is identified. It is shown that the same design-control principles that apply to a non-reacting binary system of compounds are also valid for a reactive binary system of elements for distillation columns. Application of this framework shows that designing the reactive distillation process at the maximum driving force results in a feasible and reliable design of the process as well as the controller structure.

“…Whereas, at the lowest value of the maximum driving force, separation becomes difficult and energy required to make the separation feasible is at the maximum (Bek Pedersen & Gani, 2004). Once the optimal sequence has been determined, the new optimal sequence is then simulated in step three by using a simple and reliable short-cut method (using Aspen HYSYS), where the energy used in the optimal sequence is analyzed.…”

“…To determine the design values of distillation column in a simple technique, the McCabe-Thiele has been proposed (Wang et al, 1994). In distillation column, driving force is the difference between composition in vapor phase and liquid phase as a result of difference of properties such as boiling point and vapor pressure (Bek-Pedersen & Gani, 2004). (Kemp, 2007) proposed pinch technology method which produces minimum energy usage as part of the energy monitoring.…”

This paper presents the study of the optimal synthesis of energy efficient distillation columns (EEDCs) sequence by using the driving force method. In order to perform the study and analysis, the EEDCs sequence methodology has been developed. Accordingly, the methodology consists of four hierarchical sequential steps;Step 1: Existing Sequence Energy Analysis, Step 2: Optimal Sequence Determination, Step 3: Optimal Sequence Energy Analysis, and Step 4: Energy Comparison. The capability of this methodology has been tested in designing minimum energy distillation column sequence for hydrocarbon mixture separation process. The results show that the maximum of 39.6 % energy reduction was able to achieve by changing the sequence suggested by the driving force method. It can be concluded that, the sequence determined by the driving force method is able to reduce energy requirement for hydrocarbon mixture separation process. All of this findings show that the methodology is able to design minimum energy distillation column sequence for hydrocarbon mixture separation process in an easy, practical and systematic manner.

“…In this study, a driving force based technique is used to design distillation columns by considering the energy consumption and total capital cost and using the reverse approach, the number of stages and the feed location that matches the driving force target are determined. The driving force of the two key components is defined as (Bek-Pedersen & Gani, 2004):…”

a b s t r a c tA systematic design methodology is developed for producing multiple main products plus side products starting with one or more bio-based renewable source. A superstructure that includes all possible reaction and separation operations is generated through thermodynamic insights and available data. The number of alternative processes is systematically reduced through a screening procedure until only feasible alternatives are obtained. As part of the methodology, process intensification involving reaction-separation tasks is also considered to improve the design by shifting the equilibrium reactions. Economic analysis and net present value are determined to find the best economically and operationally feasible process. The application of the methodology is presented through a case study involving biodiesel and fatty alcohol productions.
