摘    要:对铝酸钠溶液中钡盐脱硫反应进行热力学计算,分析脱硫过程中硫碱和碳碱在铝酸钠溶液中的行为。结果表明,增加温度有利于脱硫和脱碳反应的进行,尽量降低碳碱含量,有利于硫的脱除;脱硫过程应选择适当的脱硫率和终了硫碱及碳碱浓度;钡盐添加率增大有利于脱硫,但添加率过高会使脱硫剂反应不完全。

关 键 词:铝酸钠  钡盐  脱硫  热力学

Abstract:Thermodynamic calculations of desulfurization reaction with barium salt in sodium aluminate solution were conducted, and the desulfurization behaviors of sodium sulfate and sodium carbonate in sodium aluminate solution were analyzed. The results show that the rise of temperature is of benefit to the occurrence of desulfurization and decarbonization reaction, and the low content of carbon alkali can help the removal of sulfur. The appropriate desulfurization rate and final concentration of sodium sulfate and sodium carbonate should be selected during desulfurization process. The higher dosage of desulfurizer is in favor of desulfurization, but excessive amount of desulfurizer may make this reaction incomplete.
Keywords:sodium aluminate  barium salt  desulfurization  thermodynamic
