进料性质对立式隔板塔操作特性的影响

以正戊烷、正己烷和正庚烷为分离物系，在简捷计算结果的基础上，利用商业模拟软件HYSYS研究了进料热状态、进料组成和相对挥发度等进料性质对立式隔板塔操作的影响。结果表明，进料热状态对于立式隔板塔的操作稳定性和优化操作区的影响较大；进料中轻组分的含量增加不利于立式隔板塔的稳定操作。不同分离难度的物系采用立式隔板塔时的节能效果和操作特性有较大不同，分离难度越大，立式隔板塔的节能效果越明显，但优化操作区间则越窄，且操作稳定性较差。

Influence of feed property on the operation of dividing wall column

The separation of n-pentane,n-hexane and n-heptane mixture with the dividing wall column(DWC) was simulated with commercial software HYSYS,and the optimized operation region was obtained.The effects of feed property,such as feed thermal state,feed composition and relative volatility,on the operation of DWC were studied.The results demonstrated that the feed thermal state influenced strongly on the optimized operation region.And with the increase of the light component in the feed,the stable operation of DWC...
