摘要
以水为吸收液吸收煤气中的氨,采用NC2100型总有机碳/总氮分析仪分析其中的氮元素含量,通过计算得出煤气中的氨含量。试验结果表明:该法具有数据可靠、重复性好、操作简单、抗干扰性强等优点,相对标准偏差(RSD)<0.5%。
With water as the absorption liquid for the absorption of ammonia in coal gas, the Type NC2100 total organic carbon/total nitrogen analyzer is used to analyze the nitrogen element content in it, and by calculation the ammonia content in coal gas is obtained. Experimental results indicate that the method shows advantages of reliable data, good repeatability, simple operation, and strong anti-interference ability, with a relative standard deviation （RSD） of 〈 0.5%.
