The steady state composition profiles of ternary azeotropic mixtures in a continuous distillation column were investigated and calculated with feed compositions on the ridge or in the valley of the boiling temperature surfaces of the systems.
通过对泡点温度面具有代表性的两个三元共沸系统的连续精馏实验，考察了在进料组成位于泡点温度面脊（谷）上的情况下沿塔高的浓度分布，结果表明浓度分布曲线越过了脊（谷），馏出液和釜液组成落在脊（谷）的两侧。
