The content of triphenyl in coke oven gas, namely benzene, toluene, xylene (para, meta, ortho), is basically quantitatively detected using capillary chromatography, and its quantitative method is the external standard method.
This document specifies the determination principle, reagents and materials, instruments and equipment, test steps, result calculation, precision, and test report of the gas chromatography method for crude benzene content in coal gas.
This document is applicable to the determination of crude benzene content in coke oven gas generated during coking production.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has achieved the determination of benzene, toluene, and xylene content in coke oven gas through experiments using gas chromatography with good separation efficiency and fast analysis speed. And calculate the calorific value of benzene in the coke oven gas. This method has the advantages of simple operation, stable measurement results, and no need for complex calculations.
