多级翅片导流板旋转填料床精馏性能研究
Distillation performance of multi-fin baffle packing rotating packed bed
摘要
Abstract
Fin baffle packing was invented for extending gas and liquid contacting time, keeping rotating packed bed smooth running, and solving the problem of entrainment, etc. The running state and mass transfer property of rotating packed bed with multi-fin baffle packing were investigated with methanol/water mix solution at average high gravity factor βof 20. 9-130.6 , reflux ratio R of 1.5-4, feedstock flow q of 25-50 L/h, and atmospheric pressure. The experimental data show that the methanol mass fraction of distillate increases firstly and then decreases with the average high gravity factor βand the feedstock flow R , and increases with the reflux ratio, which can reach 99% (mass fraction) at the optimum operating conditions of β= 51. 5, R = 4 and q = 35 L/h. With MATLAB software, the significance of operating conditions from high to low level is sequenced by reflux ratio, average high gravity factor and feedstock flow.关键词
