摘要

Abstract

The conventional distillation is hard to accomplish the separation of acetonitrile/ethyl acetate/

-hexane mixture. Herein

a heterogeneous azeotropic distillation (HAD) without adding entrainer is proposed to separate ternary mixture. The proposed scheme is optimized

via

the simulated annealing algorithm and minimum total annual cost (TAC) is used as objective functions. To minimize energy consumption

heat pump is added on the basis of optimal heterogeneous azeotropic distillation and heat integration technology is used to further improve the energy recovery. The TAC

gas emission

energy consumption and exergy destruction are used to discuss the economy and environmental protection of processes. Among all the processes

the heat pump with higher preheating temperature (HPT) assisted HAD process by combining with heat integration (HAD-HPT-HI) has best performances on economic

environment

energy and exergy. Compared with conventional HAD process

the HAD-HPT-HI achieves the reductions of 52.17%

68.86%

65.87% and 65.46% on TAC

total energy consumption

gas emissions and exergy destruction

respectively.
