Natural gas as a clean, efficient and green energy, has become an important component of industrial production and daily life. The presence of sulfide in natural gas not only pollute the environment, health hazards, but also corrosion of pipelines, catalyst poisoning, loss of activity. Therefore, accurate determination of sulfur compounds in natural gas can provide technical support for the desulfurization technology research and product quality control, production of natural gas to industrial safety and security.
Tengzhou City Technology Co., Ltd. established GC7990 Xiangying analysis by gas chromatography - spectrophotometric determination of four LNG import sulfur form of flame. Discussion on the column, inlet temperature, split ratio, column flow, temperature program and FPD detectors, etc. on the determination results. Under optimized conditions, the evaluation of the reliability of the method. Mass concentration of four kinds of forms sulfide in 10.0 ~ 200.0μg / L range, the logarithm of the logarithm of the peak area showed a good linear relationship, linear correlation coefficient r 3 between 0.983 to 0.999 in 2, the detection limit is 1.7 ~ 7.7μg / L, the relative standard deviation of the measurement results is 0.56% ~ 0.68% (n = 5). Determination of forms of sulfur gas standard gas by this method, the measured value compared with the standard value, relative error is -1.6% -1.2%. This method has a high accuracy, can be applied to the analysis of four natural gas imports form sulfur.
天然气作为清洁、高效、绿色能源,已经成为工业生产和日常生活的重要组成部分。天然气中硫化物的存在不仅污染环境、危害健康,还会腐蚀管线,触媒中毒,失去活性。因此准确测定天然气中的含硫化合物可为脱硫技术研究和产品质量控制提供技术支持,对天然气工业安全生产和安。
滕州市翔鹰分析技术有限公司建立GC7990气相色谱–火焰光度法测定进口液化天然气中4种形态硫的方法。探讨了色谱柱、进样口温度、分流比、柱流速、升温程序和FPD检测器等对测定结果的影响。在优化的实验条件下,评价了方法的可靠性。4种形态硫化物的质量浓度在10.0~200.0μg/L范围内,其对数与峰面积对数呈良好的线性关系,线性相关系数r在0.983 3~0.999 2之间,检出限为1.7~7.7μg/L,测定结果的相对标准偏差为0.56%~0.68%(n=5)。用该法测定天然气形态硫标准气体,测定值与标准值相比,相对误差为–1.6%~–1.2%。该方法具有较高的准确度,可应用于进口天然气中4种形态硫的分析。
