Abstract
The separation of ethanediamine (as a crucial chemical intermediate) and water is a tough issue in chemical processes. The energy-saving measures of existing separation schemes are still worth further investigation. In this work, a novel method combining the organic Rankine cycle (ORC) with a heat pump (HP) assisted azeotropic divided wall column (ADWC) is proposed to explore the energy saving potential of the conventional process, so as to realize the efficient utilization of process energy. Targeting the maximum annual net profit and thermodynamic efficiency, an improved multi-objective genetic algorithm (due to the trade-off between the two objectives) is used to optimize the parameters of the ORC systems with six candidate working fluids. Then, the economic and efficiency indicators are compared and evaluated. The results prove that the HP-ADWC integrated ORC scheme with working fluid R123 can save 11.58% of TAC compared with the existing HP-ADWC process, and the thermodynamic efficiency reaches 14.47%.
