Abstract
In this paper, emphasis is given on an industrial case study involving the purification of ethylbenzene through solvent-based extractive distillation - the design of experiments, the collection of data and the validation of the performance of the selected solvent as well as the optimal design of the separation process, are covered. Well-known methods and tools from CAPE, such as, selection of solvents through CAMD (Computer-Aided Molecular Design), design of the extractive distillation columns through driving force based technique for optimal process synthesis/design, and, process simulation, have been used. The objective of the experimental work has been to validate the estimated performance of the selected solvents as well as to clarify the uncertainties in the final design. Using the collected experimental data, it has been possible to perform a sensitivity analysis and through it, verify the solvent selection, process design as well as a cost analysis to make the final evaluation of the new design. The paper presents the new, combined analysis, the evaluation and validation of the process design. ฉ 2009 Elsevier B.V. All rights reserved.
