水分对喷气燃料质量性能的影响研究

Study on the effect of moisture on the quality performance of jet fuel

较高品质的喷气燃料能有效避免航空发动机发生故障。燃料中水分因为高空低温环境下结冰或储罐中滋生微生物而对燃料品质与性能造成影响,为探究在油轮空载时向货油舱内灌注压舱水是否会对喷气燃料含水量造成影响,在不同油水比例、不同油水接触时间和不同品质水分条件下,对高闪点喷气燃料含水量进行考察,并定量分析水分对于高闪点喷气燃料外观及理化性质的影响。另进行海水对高闪点喷气燃料其他理化性质影响探究。得出结论:油水比例、不同品质水和接触时间对高闪点喷气燃料中的含水量影响较小,但在海水环境下会影响喷气燃料硫含量、总酸值等性质。在油库中,可以考虑用水代替喷气燃料作为冲洗、试压介质,减少油料浪费,提高冲洗操作的安全性。

Higher quality jet fuel can effectively avoid aircraft engine failure.The moisture in the fuel will affect the quality and performance of the fuel because of freezing in the high altitude and low temperature environment or microorganism breeding in the storage tank.In order to explore whether the filling of ballast water into the cargo tank when the tanker is empty will affect the water content of jet fuel,the water content of high flash point jet fuel was investigated under different oil-water ratios,different oil-water contact times and different quality moisture conditions,and the influence of moisture on the appearance and physicochemical properties of high flash point jet fuel was quantitatively analyzed.In addition,the influence of seawater on other physical and chemical properties of high flash point jet fuel was explored.It is concluded that the oil-water ratio,different quality water and contact time have little effect on the water content in high flash point jet fuel,but affect the sulfur content and total acid value of jet fuel in the seawater environment.In the oil depot,water can be considered instead of jet fuel as the flushing and pressure test medium to reduce oil waste and improve the safety of flushing operations.
