| 摘 要： | 本文以ＮＨ３－Ｈ２Ｏ系统Ｇｉｂｂｓ自由能、熵、焓和汽液相平衡的热力学模型为基础，用松弛法进行了无水氨精馏塔的模拟计算。改变无水氨采出比、回流比（直汽量）和进料板位置均影响蒸馏效果。

| Abstract: | The performance of ammonia-water distillation used in Phosam process ha.s been simulated. The Schulz's thermodynamic modle of NH3-H2O system has been used, while relaxation method used for simulation. Results shows that the distillation efficiency is sensitive to anhydrous ammonia yield, reflux ratio and feed position. |
