摘要
本文导得,用轻关键组分对重关键组分的相对挥发度的两端值等六个参量表示 Fenske 方程的精确解,适用于计算多元理想物系恒压精馏的最少理论板数。由此,对该物系的非清晰分割问题建立了直接求解法。
Six parameters such as relative volatility end values of light key components versus heavy key components expressing the precise solution of Fenske Equation are derived,which are applicable to calculating the theoretical minimum number of tower plates in rectifying ideal polyvalent components under constant pressure,and from which a direct solution is derived for roughing out the components.
