Vapor-liquid equilibrium data for efficiency estimation of tray columns

Vapor-liquid equilibrium data are the prerequisites for determining column efficiencies. For this purpose, industrial binary distillation operations are selected from the literature. At representative column pressures, high resolution data are obtained for the mixtures using suitable thermodynamic models in Aspen Plus (v10).

气液平衡（vapor-liquid equilibrium, VLE）数据是确定精馏塔塔板效率的先决条件。为此，本数据集从公开文献中遴选工业级二元精馏操作案例，并在具有代表性的塔压条件下，通过Aspen Plus（v10）中的适配热力学模型，获取了对应混合体系的高分辨率气液平衡数据。
