NH_3-SO_2-SO_3-H_2O系统相图及其应用

Phase Diagrams of NH3-SO2-SO3-H2O System and Their Application

本文介绍利用NH_3—SO_2—SO_3—H_2O水盐体系各主要相图对氨法处理硫酸尾气的实际操作进行各种近似的运算。例如,求取饱和吸收液的结晶率,选取合理的工艺条件等。

The phase diagrams of NH3-SO2-SO3 -H2O system were applied to the ammonia scrubbing process for treating tail gas from sulphuric acid plants to approximately calculate operating parameters such as crystallization rate of saturated absorption solution and to choose rational process conditions.
