为了减小Aspen模型模拟间歇精馏过程初始参数设置不准确带来的模型误差，使模型优化间歇精馏操作参数更加合理，提出了采用均匀设计的试验安排方法，并以桃醛粗品小试实验分离桃醛为研究对象，对Aspen模型模拟间歇精馏时的初始参数如理论板数、冷凝器持液量和每块理论板持液量进行优化。经过优化后得到理论板数为35块，冷凝器持液量为0.005 2 kg，每块理论板持液量是0.000 8 kg，参数更加接近实际精馏塔的理论参数，为后续的操作参数优化减少误差。

In order to reduce the model error caused by the inaccurate initial parameter setting in simulating batch distillation process by Aspen model and make the batch distillation operation parameters in model optimization more reasonable,the test arrangement by uniform design method is proposed.Taking the separation experiment of crude peach aldehyde as the research object,the initial parameters for simulation of batch distillation by Aspen model such as the number of theoretical plates,the liquid holdups in condenser and on each theoretical plate are optimized.After optimization,the number of theoretical plates is 35,the liquid holdup in condenser is 0.005 2 kg and the liquid holdup on each theoretical plate is 0.000 8 kg.These parameters are closer to the theoretical parameters of actual distillation column,which is helpful to reduce error in the subsequent optimization of the operating parameters.
