芳烃联合装置石油馏分中微量氯的测定

THE DETERMINATION OF TRACE CHLORINE IN PETROLEUM FRACTION FROM THE INTEGRAL AROMATICS UNIT

通过试验选择了一种国产的裂解试剂（NaOH溶液）代替昂贵的美国进口试剂联苯基钠，用于石油馏分中微量氯的分析。结果表明：当试样中Cl-浓度在一定范围内时，20％的NaOH溶液在一定条件下与试样中有机氯的裂解反应效率基本衡定，校正系数是一常数，为定量分析提供了一定的实验依据。在结果计算时，通过使用校正系数的方法使20％的NaOH溶液完全可以代替联苯基钠试剂，从而大幅度地降低了微量氯的分析成本。使分析方法（UOP395）更具有实用性。

By experiment, one kind of China made cracking reagent (NaOH solution) has been selected to replacethe expensive reagent-sodium biphenyl imported from America and used to analysing trace chlorine inpetroleum fraction. The result indicated that when the concentration of Cl- in the sample is within specifiedlimits, under specified conditions the cracking reaction coefficient that 20 percent NaOH solution reacts withorganic chlorine in the sample is basically constant, and the correction factor is a constant. while counting theresult by means of using correction factor, 20 percent NaOH solution can completely replace the reagentsodium biphenyl thereby the analysing cost of trace chlorine can be reduced by a big margin. And theintroduced analysing method(UOP395 )has more applicability.
