本文建立了一个动态模型，用于模拟中试规模的连续15板精馏塔分离乙醇、异丙醇和异丁醇混合物的暂态行为。在回流比、进料流量和进料组成阶跃变化的情况下，通过实验收集的瞬时响应数据对预测的准确性进行了评估。结果表明，在非稳态条件下模拟多组分精馏是可行的，并取得了较好的效果。建议进一步改进以提高精确度
Abstract In this work, a dynamic model was developed to simulate the transient behaviour of a pilot scale, continuous, siagewise, 15 plate distillation column separating a mixture of ethanol, iso-propanol and isobutanol. The accuracy of the predictions was assessed by transient response data collected during experiments under step changes in reflux ratio, feed flow rate and feed composition. Results demonstrated the feasibility of simulating multicomponent distillation under unsteady state conditions with fairly good success. Further improvements were suggested for a better accuracy
