汽油中微量水分含量的研究

用卡尔费休库仑法对成品汽油的微量水含量进行了分析,并对上海高桥分公司成品汽油的调和组分汽油的微量水含量进行了跟踪测定;分析了汽油微量水的来源及影响因素,指出了MTBE作为高辛烷值汽油调和组分,具有较强的吸水性,并给出了有针对性的降低汽油水含量的措施。

Study and Determination of Trace Water in Gasoline

By Coulometric Karl Fischer Titration, trace water content in finished gasoline was determined as well as trace water content in gasoline blending stocks of SINOPEC Shanghai Gaoqiao Company. Sources and influence factors of the trace moisture were analyzed, and it’s found that MTBE as high octane gasoline blending component has strong water absorption, that is the major factor leading to higher water content. At last, the targeted measure was put forward to reduce water content in gasoline.
