塔板数计算式的推导

Derivation of Equation of Theoretical Plates for Absorption

本文采用代数法和几何法推导了在气体吸收过程中,当气液两相做逆流操作时,平衡线和操作线都为直线情况下的理论板数和气相进出口浓度之间的关系式。

For gas absorption, when gas and liquid were countercurrent flowing and both the equilibrium line and the operating ling were linear, the relation between the number of theoretical plates and gas in and out concentration was derived by algebraical method and geometrical method, respectively.
