摘要
本文通过对SO_2-H_2O系的气—液—固三相平衡计算,分析了溶液pH值及温度和SO_2的分压对于吸收废气中低浓度SO_2的影响,阐述了用碱液或金属氧化物吸收SO_2的理论依据。所提供的基本热力学计算数据和方法可供涉及SO_2—H_2O系的平衡计算参考。
The paper analyses the effects of solution pH, as well as gas-phase partial pressure of SO_2 and temperature on absorbing SO_2in waste gas with the calculation on gasllquid-solid triphase equilibrium of SO_2-H_2O system, and gives the theoretical considerations on SO_2 absorbed by alkalinous solution or metal oxide. It is possible that the given basic thermodynamic calculation datum and method are for references to the rest including the equilibrium of SO_2-H_2O system.
