| 摘 要： | 本文对低浓度气体吸收操作中吸收剂再循环时气体出塔浓度的变化规律作了探讨。结果表明，当改用吸收剂再循环时，气体出塔浓度ｙ＿２＇上升，吸收率下降，但ｙ＿２＇的变化幅度均小于两个具有参照意义的浓度ｙ＿２，ａ及ｙ＿２，ｂ。同时，结果还表明，当吸收剂用量较大时，由于采用吸收剂再循环所造成的返混对传质过程的影响远大于吸收剂用量较小的情况。这一分析对吸收塔的设计与操作具有指导意义。

| Abstract: | The variation pattern of outlet gas concentration when absorbent recycles in low-concentrations gas absorption tower was studied in this article.It was shown that the rise in outlet concentration due to absorbent recycling was less than two reference values y2 ,and y2, b.This analysis is of value in the design and operation of absorption columns. |
