双加法硝酸生产氧化和吸收效果计算及应用

Calculation and Application for Effect of Oxidation and Absorption of Dual-pressure Nitric Acid Production

根据双加压法硝酸生产的基本原理,结合实际推导出其两大主要过程—氨催化氧化和氮氧化物吸收效果的计算公式,应用该公式为判断铂催化剂活性,调整工艺指标,分析氨的消耗提供依据。

According to the basic principle of dual-pressure process of nitric acid production,it deduced the formula for effect of its two main processes,which were catalytic oxidation of ammonia and nitrogen oxides absorption actually. Application of the formula,it provided the basis for determining the activity of a platinum catalyst,adjusting process parameters process indicators and analyzing of consumption of ammonia.
