Research on determination method of ammoniac content in coke oven gas
The accurate analysis and control of ammonia content in coke oven gas could effectively control the nitrogen oxides in the exhaust gas after the combustion in iron and steel complex enterprises.There were two methods for the determination of ammonia content in coke oven gas:neutralization titration and Nesser's reagent spectrophotometry.The comparison of two methods for the determination of ammonia content in coke oven gas after the desulfurization by the HPF method was carried out.And it was found that neutralization titration was unstable because of the acidity of coke oven gas.However,Nesser's reagent spectrophotometry was not affected by the acidity of coke oven gas,which was much more suitable for the ammonia content detection in purified coke oven gas after the HPF gas desulfurization.
