摘要
测定中缅管输原油中9种元素,为原油国别鉴定、原油溯源提供依据,为中缅管输原油运输及下游的冶炼过程提供科学基础。采用灰化碱熔-电感耦合等离子体发射光谱法对中缅管输原油中9种元素进行测定。结果表明,中缅管输进口5个国家的原油中含有Al、Si、V、Ni、Fe、Na、Ca、Zn 8种元素,原油中均未检出P元素。8种元素中Fe含量占比75.73%,V含量占比10.87%,Si含量占比4.73%,Ni含量占比4.18%,其余元素占比4.56%。通过分析得出,中缅管输进口的5国原油Si/V、Ni/V比值均小于1,呈现出海相原油的特性,不同油种元素的含量存在一定差异,且有一定的规律性,各油种间Ni/V、Si/V比值相差不大,Fe/V比值的波动较大,可以按此对5个国家原油进行溯源。
The determination of nine elements in crude oil transported by China-Myanmar pipeline provides a basis for crude oil identification and traceability,and provides a scientific basis for crude oil transportation and downstream smelting process.Nine elements in crude oil from China-Myanmar pipeline were determined by ashlized alkali fusion inductively coupled plasma emission spectrometry.Eight elements,such as Al,Si,V,Ni,Fe,Na,Ca and Zn,were detected in the crude oils from the five countries imported from the China-Myanmar pipeline.but P element was not detected in the crude oils.The contents of Fe,V,Si,Ni and other elements were 75.73%,10.87%,4.73%,4.18%and 4.56%,respectively.Through analysis,the sino-burmese pipeline crude oil imports of five countries Ni/V and Si/V ratio was less than 1,presented the characteristics of crude oil at sea,oil of different kinds of element contents in there was a difference,and had the certain regularity,between each kind of Ni/V and Si/V ratio were similar,the Fe/V ratio of volatile,can according to the five countries of crude oil for traceability.
