This paper presents a new methodology for optimising the energy efficiency of a crude distillation unit without trading off the product quality and process throughput. It incorporates the second law of thermodynamics which indicates how well a system is performing compared to the optimum possible performance and hence gives a good indication of the actual energy use of a process. Bootstrap aggregated neural networks are used for enhanced model accuracy and reliability. In addition to the process operation objectives, minimising the model prediction confidence bound is incorporated in multi-objective optimisation to improve the reliability of the optimisation results. The economic analysis of the recoverable energy (sum of internal and external exergy losses) reveals the energy saving potential of the method. The proposed method will aid the design and operation of energy efficient crude distillation columns.
