摘要
建立了缔合体系相平衡模型,并对含缔合组分汽相焓进行了校正,液相用NRTL、Wilson方程修正其非理想性计算出的汽液相平衡数据及焓值,用于缔合体系多股进料精馏模拟取得了满意的效果。本软件采用三对角矩阵法求解精馏过程的MESH方程组,用Visual Basic 6．0开发出缔合体系精馏模拟软件,同时软件也包括了一般体系的多元复杂精馏模拟。
The vapour-liquid equilibrium model of association system was established, and vapor enthalpy of association system was corrected. NRTL and Wilson equations in the liquid phase were used to correct the non-ideal behavior. The simulation of association system several-feeds distillation process gained satisfactory effect by applying the vapor-liquid equilibrium and enthalpy data of calculation. The MESH equations were solved by trigonometric matrix in distillation simulation process. The software for simulating distillation process of association system was programmed using Visual Basic 6.0. The software can be also used to simulate distillation process of general systems.
