Abstract: 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.
