摘要：

A bio-ethanol column as part of an ETBE (ethyl-tert-butylether) plant is optimized in view of OPEX costs, CO2 emissions as a sustainability indicator and the columns ethanol product stream. Therefore, three scalarization methods, i.e. the weighting approach, the epsilon-constraint method and a modified normal boundary intersection method, and a genetic algorithm (NSGA-II) are implemented and applied to two optimization cases. Additionally, a heat exchanger fouling model is incorporated to account for highly nonlinear maintenance interval effects in the reboiler of the column.
