循环气氨含量测定方法的改进

Improvement on Method for Determination of Ammonia Content in Recycle Gas

合成氨生产过程中,需对循环气进、出口氨含量进行控制,借以判断H2和N2转化为NH3的情况。通过对传统的硫酸吸收测定法进行改进,使测定结果稳定,对指导生产具有十分重要的意义。

In the production of ammonia, it is necessary to control the ammonia content in the recycle gas at the inlet and outlet, so as to judge the conversion to NH3 of H2 and N2. By improving the conventional method of determination by sulfuric acid absorption, the results of determination becomes stable, having a great significance in guiding production.
