摘要

本文针对完全能量耦合精馏塔，基于Fenske-Underwood-Gilliland方程建立了完整的简捷设计方法，得到了各塔的实际理论板数、适宜的进料和侧线液相采出位置以及各塔回流比等参数。并在此基础上通过严格模拟，对完全热耦合精馏塔的中间组分分配比β、气相分割比Rv和液相分割比Rl等参数进行了优化，得出了它们对再沸器热负荷的影响规律。

Abstract

A short-cut design method based on Fenske-Underwood-Gilliland equations for fully thermally coupled distillation column is proposed.The approach uses a shortcut method that estimates the initial specifications for the theoretical tray numbers

feed and liquid withdraw locations and the reflux ratio.By the rigorous simulations

the overhead fraction of the distributed component

as well as the split ratios for the gas and liquid phases Rv and Rl are optimized.And the influence of parameters β，Rv and Rl on the reboiler duty are also found respectively.
