摘要
本文系统研究了低温精馏氢同位素分离中总板数、进料位置、回流比、采出率等操作条件对系统分离性能的影响,获得了精馏柱上的浓度和温度分布。随着进液位置向底端移动,再沸器和冷凝器中HD浓度均减小;随着回流比的增大,再沸器和冷凝器中HD浓度均减小;顶端采出率增大,再沸器中HD浓度明显增大;在相同的总板数下,H2/HD和D2/DT两个体系的分离特性明显有差别。
A comprehensive study was carried out to uncover the influence of process conditions, such as total stage number, feeding point, reflux ratio and distillation rate, on the separation capability. Both concentration and temperature distribution along the distillation column were obtained. As the reflux ratio increases and the feeding point moves towards the bottom, HD concentrations in condenser and reboiler are decreased. With the increase of distillation rate the HD concentration in reboiler increases as well, and there are remarkable differences in separation performance between H2/HD and D2/DT system.
