摘要:
无硫加臭剂作为一种面向未来的环保型燃气添加剂,建立有效可行的测定方法,有利于判定商品天然气中的无硫加臭剂含量,为确保燃气的安全供应提供基础数据。采用气相色谱法对天然气中的无硫加臭剂组分进行测定,使用了HP-INNOWAX毛细管柱和氢火焰离子化检测器进行检测,无硫加臭剂的检测限可达到1 mg/m3。该方法操作简单,可行性好,已用于天然气中无硫加臭剂的测定,取得了令人满意的结果。 

Abstract:
As a future-oriented environment-friendly gas additive, sulfur-free odorant has established a feasible and effective measurement method, which is beneficial to determine the content of sulfur-free odorant in commercial natural gas and provides basic data for ensuring the safe supply of gas. This method uses gas chromatography to determine the sulfur-free odorant components in natural gas. HP-INNOWAX capillary column and flame ionization detector are used for detection. The detection limit of sulfur-free odorant can reach 1 mg/m3. The method is simple to operate and has good feasibility. It has been used in the determination of sulfur-free odorant in natural gas and has obtained satisfactory results.
