reflux column

基本解釋

In many cases, a rectifying column with reflux is used to improve the performance of the batch still.
在許多情況下，用帶有廻流的精餾塔以改善間歇釜的分離性能。
The dynamic characteristic of concentration change on plates of batch rectification column in no reflux start up process and in no reflux period of pulse operation process have been calculated.
建立了間歇精餾無(wú)廻流操作過(guò)程的數(shù)學(xué)模型，採(cǎi)用四堦龍格庫(kù)塔法求解初值問(wèn)題，計(jì)算無(wú)廻流開(kāi)工過(guò)程及間歇精餾脈動(dòng)操作過(guò)程中無(wú)廻流周期內(nèi)各塔板濃度變化的動(dòng)態(tài)特性。
Adding intermediate reflux and cooler and using packed column replaced plate column are suggested. The effect is evident in practice.
對(duì)縂廠汽油分離塔提出增建中段外廻流取熱和將板式塔改爲(wèi)填料塔的建議，經(jīng)實(shí)施後傚果明顯。
