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...

Existing refinery distillation systems are highly energy-intensive, and have complex column configurations that interact strongly with the associated heat exchanger network. An optimisation approach is developed for existing refinery distillation processes. The optimisation framework includes shortcut models developed for the simulation of the existing distillation column, and a retrofit shortc...

Vapour recompression system has been used to enhance reduction in energy consumption and improvement in energy effectiveness of distillation columns. However, the effects of certain parameters have not been taken into consideration. One of such parameters is the column heat loss which has either been assumed to be a certain percent of reboiler heat transfer or negligible. The purpose of this st...

based on two integration steps, an optimization framework is proposed in this work for the synthesis and design of complex distillation sequence. the first step is to employ heat integration in sequence and reduce the heat consumption and total annual cost of the process. the second one is to increase the exergetic efficiency of sequence by generating power in implemented expanders in sequence....
