摘要
针对分离丙烯腈-水二元共沸体系不同压力下共沸组成变化,利用Aspen Plus化工工艺模拟软件实现了丙烯腈-水共沸体系的变压精馏分离。采用序贯迭代算法以最小年总费用为目标确定了丙烯腈-水变压精馏的最佳稳态工艺参数。对于进料组成各为50%摩尔分数的丙烯腈-水的变压精馏工艺,其精馏序列为先低压后高压,操作压力分别为0.1 MPa和0.6 MPa,最小年总费用为1.25451×10^(6)$。
Regarding the separation of the acrylonitrile-water binary azeotropic system under different pressures,the pressure-swing distillation of the acrylonitrile-water system was implemented using the Aspen Plus chemical process simulation software.The optimal steady-state process parameters for the acrylonitrile-water pressure-swing distillation were determined using a sequential iterative algorithm,with the objective of minimizing the annual total cost.The study demonstrated that for a feed composition of 50%mole fraction each of acrylonitrile and water,the preferred distillation sequence was low-pressure distillation followed by high-pressure distillation,with operating pressures of 1 atm and 6 atm,respectively.The minimum annual total cost was determined to be 1.25451×10^(6)$.
