Abstract: The exhaust gas of zinc smelting was absorbed by alkaline residue—a Na2CO3·10H2O containing by product in producing hydrazine hydrate. Sodium Sulfite was obtained. The influences of SO3 content in the exhaust gas of zinc smelting, the specific gravity of liquid alkali and the pH value of neutralization liquid on sulfur removal process, sulfur removal efficiency and product quality were investigated.

摘要: 利用水合肼生产过程中副产的碱渣(含Na2CO3·10 H2O)吸收锌冶炼烟气,得到结晶亚硫酸钠。重点考察了尾气中SO3含量、碱液比重、中和液pH值对脱SO2工艺、效率和产品的影响。
