Next, the physical properties and vapour liquid equilibrium data must be collected, and finally the type of absorber is chosen and designed. 其次，必须收集物理性质和汽一液平衡数据，最后才是选择和设计吸收器。
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。
