発明の名称 (英語) HIGHLY ACCURATE CORRELATING METHOD FOR PHASE EQUILIBRIUM DATA, AND PHASE BALANCE CALCULATION METHOD
発明の概要(英語)

Provided are: a method for accurately deriving phase equilibrium from existing phase equilibrium data for wide-ranging phase equilibrium data including 2-component system vapor-liquid equilibrium data

a method and device for designing and controlling the isolation and refining of components using said method

and a device designing program for designing these design or control devices. Using a 2-component system phase equilibrium measurement data, the critical point carryover factor X represented by formula (22) below and infinite dilution pressure gradient Y1 and Y2 represented by formulas (24) and (25) are calculated (in the formula, Pc1 is the critical pressure of component 1 in the 2-component system, p1s and p2s are the vapor pressures of component 1 and component 2 respectively at temperature T, and gammai [infinity] represents the infinite dilution activity coefficient with respect to the component i in liquid phase), the X and Y1and Y2 are correlated, new infinite dilution activity coefficient gamma1 [infinity], gamma2 [infinity]or 2 component system parameters A, B are calculated from the X-Y1 correlation and X-Y2, and phase equilibrium is calculated from the obtained gamma1 [infinity] and gamma2 [infinity] or from A and B. The design and control of component isolation and refining devices, such as distillation columns, is carried out using values thus obtained. Critical point arrival rate X: (22) infinite dilution pressure gradient Y1 and Y2: (24), (25)
