If no azeotropes are encountered , both overhead and bottom products may be obtained in any desired purity if enough plates and adequate reflux are provided 只要不出现恒沸物，只要塔板数足够多，回流量足够大，就可以获得任意纯度的塔顶和塔底产品。
The total efficiency , plate efficiency , foam efficiency , film efficiency of compound tray , and the total efficiency of the other thee types of plate was detected 测定了复合塔板的全塔效率、塔板效率、泡沫区和液膜区效率以及其余三种塔板的效率。
The test was made on the compound tray , dual flow tray , sieve tray and valve tray for mass transfer efficiency with in - diameter 300 mm column using ethanoi and water system 在直径300mm的精馏塔内，以乙醇-水为介质，进行了复合塔板、穿流筛板、筛板和浮阀塔板的传质效率的研究。
One of the main aspects of research on distillation column with trays is the fluid field and mass transfer on the trays by the method of computational fluid dynamics ( cfd ) <中文摘要> =在蒸馏设备中，板式塔研究的一个重要方面就是应用计算流体力学对塔板上流体流动状况及传质过程的研究。
In a transparent plexiglas column with inner diameter of 600mm , the comparison of downcomer capacities between ctst tray and fl valve tray were studied with the air - water and foaming systems 在600mm的透明有机玻璃塔中，采用空气?水和易发泡物系，对两种塔板的降液管操作能力进行了比较研究。
A numeric method for computing limiting concentration of light component in the distillate of binary batch distillation under constant reflux ratio and hold - up in the column is introduced 摘要介绍了采用恒回流比操作方法，在塔顶、塔板持液时，间歇精馏二元理想混合物，馏出液中轻组分极限浓度的数值计算方法。
Simulation and optimization of distillation processes are usually carried out using equilibrium model wherein the vapour phase is assumed to be in equilibrium with the liquid phases leaving the theoretical stages 精馏过程的仿真和优化计算通常都是基于平衡模型。平衡模型假设离开塔板的汽相与液相处于平衡状态。
Or , if have the same operation loads , the downcomer size of ctst tray can be designed smaller than the fl valve tray . it was found that ctst plates have bigger operating capabilities than other traditional plates in coping with foaming systems 总之，在处理两种物系，尤其是易发泡物系时， ctst与f1浮阀等传统塔板比较，其降液管操作能力大得多。
The mass transfer model of the foam was established on the basis of the penetration theory , and the mass transfer model of the compound tray was obtained according to the mass transfer model of the foam and frb model in packing 以溶质渗透理论为基础，建立了泡沫层的传质模型，根据泡沫层的传质模型和规整填料的fbr传质模型，获得了预测复合塔板传质效率的模型。
In this paper , according to the need of developing new style column , new style fixed - valve tray - rectangular fixed - valve tray with fold edges and common rectangular fixed - valve tray were studied from experiments and cfd simulation 本文针对开发塔设备新类型的需要，从实验和cfd模拟两方面对新型的固定阀塔板-带折边矩形固定阀塔板以及普通的矩形固定阀塔板进行了研究。
