- The width of the pseudo-pinch point zone was affected by reflux ratio and relative volatility. 在多元物系间歇精馏过程中,拟夹紧区的宽度随回流比和相对挥发度的大小而改变;

- The experimental results showed that DMF with salt had higher relative volatility of C4 and was better than DMF for separating C4. 实验结果表明,加盐DMF分离能力强于溶剂DMF,C4在同温同压下的相对挥发度比DMF中的大。
- Under the assumption of constant molar overflows and relative volatility, a simplified model is developed to study the behavior of the distillation process under consideration. 假定液体持液量和待分离的体系的相对挥发度均保持不变,建立了该塔的一个简化的模型,由此得到各组分在整个塔中的分布情况。
- The influence on separating non polar systems of C4 fractions by extractive distillation with addition of salt in terms of relative volatility at infinite dilution was studied. 以C4为例利用无限稀释相对挥发度的试验测定结果,研究加盐萃取精馏分离非极性体系的影响规律。试验研究表明,溶剂加盐能够提高C4组份之间的相对挥发度,且比一般有机溶剂效果明显;
- The relative volatility measured by gas-liquid equilibrium pot proved that GE was a very effective solvent to separate the mixture of methanol-water-DMM. 依据相似体系下萃取剂的选择情况,选取乙二醇为萃取剂,并采用单循环汽液平衡釜验证其可行性。
- Figure 1 also reveals that errors in relative volatility are a problem only at low relative volatilities. 图1也显示出错误的相对波动是一个问题,只有在相对低的波动。
- Efficiency of conventional separation,namely azeotropic distillation or extractive distillation,was relatively low due to very close relative volatility of benzene and cyclohexane. 由于苯和环己烷的相对挥发度非常接近,利用传统分离方法(如萃取精馏或共沸精馏)分离苯-环己烷混合物的分离效率较低。
- In this method it is not necessary to make those assumptions that the relative volatilities are constant throughout the dolumn and/or molal overflows are constant. 本法无需作全塔相对挥发度恒定和/或恒摩尔回流之类简化假定。
- The relatively volatile liquid hydrocaroons, is called gas condensates. 较易挥发的液态烃,又称气体凝析液。
