| 摘 要： | 针对催化裂化烟气成分日益复杂化给催化设备带来的危害 ,从热力学角度分析并讨论了影响烟气露点温度的因素 ,尤其从相平衡理论推导了烟气中的露点温度与烟气组成的关系。结果表明 :混合体系的露点温度与硫酸蒸气的分压有关 ,与液相中水的浓度有关 ,与体系的总压有关 ;与烟气中的氮氧化物 (NOX)或碳氧化物 (COX)含量无直接关系 ,其对露点温度的影响是通过对总压的影响表现出来的 |

| Abstract: | As the composition of FCCU flue gas becomes increasingly complicated, it imposes a great danger to the FCC equipment. In this paper, the factors affecting the dew point temperature of flue gas were analyzed and discussed in respect of thermodynamics, especially the relationship between the dew point temperature and the composition of the flue gas based upon phase equilibrium. The analysis indicated that the dew point temperature of the mixed system relied on the partial pressure of sulfuric acid vapor, water concentration in liquid phase and total pressure of the system and it had no direct relation with the contents of NOx and COx in the flue gas. Their effect on the dew point temperature was shown by affecting the total pressure of the system. |
| Keywords: | dew point temperature mixed flue gas thermodynamics |
