低浓度吸收操作线的讨论

Discussion on Operating Line of Dilute Concentration Absorption

本文讨论了低浓度吸收操作线的各种表达式。并指出下式具有最佳近似,即y=L_b/G_bx+y_a-L_b/G_bx_a式中G_b,L_b代表塔底处的气,液相摩尔流率,y_a,x_a代表塔顶处的气,液相摩尔分率,y、x代表塔中任一截面处的气、液相摩尔分率。

Various expressions for operating line of dilute Concentration absorption have been discussed, and the optimum approximation lies in the following equation.where G_b and Lb are molal flows of gas phase and liquid phase at the bottom in the y_a and x_a mole fractions in gas and liguid at the top in the tower, and y and x mole fractions in gas and liquid at ang cross section in the tower.
