直接蒸汽加热时二元连续精馏塔提馏段操作线方程

Discussion on the Stripping Stage Operating Line Equation of the Two component Continuous Rectification Tower with Direct Steam Injection

提出了直接蒸汽加热时二元连续精馏塔以ｘＦ、ｘＤ、ｘＷ、ｑ、Ｒ表达的提馏段操作线方程，并对直接蒸汽加热和间接蒸汽加热时的提馏段操作线方程进行了讨论和比较．

This paper presents the stripping stage operating line equation of two component continuous rectification tower with direct steam injection. The equation is expressed with such parameters as x F、x D、x * W q and R. The anthors discuss the presented equation and compare it with the equation of rectification tower which has interface heat exchanger in bottom.
