成品油管道输送混油检测技术

成品油顺序输送过程中,两种油品交替会产生混油。混油降低油品品质,流经泵站会使泵电机产生较大电流波动,还会增加油品处理成本。及时准确掌握混油界面情况,对安全经济生产具有重大意义。总结了浮子式和振动式密度型检测法、示踪检测法、放射型检测法、电容型检测法以及光学检测法的检测原理、检测方法、优点和缺点等。提出在分析不同油品特点基础上,有针对性的选择检测方法,从而最大程度的保证检测精度。

Detection Technique of Oil Contamination in Batch Transportation

In batch transportation of products oil, transmiting two or more oils would produce contamination, which would degrade oil quality, make pump motor generating a large current fluctuations and increase the cost of oil processing. Timely and accurately master the position of contamination interface had great significance to the safe and economic pro- duction. The detection principle, detection method and the advantages and disadvantages of density detection method, tracer detection method, radiation detection method, capacitive detection method and optical detection method were intro- duced. Based on different oil characters, the detection method was selected aimly to make sure the detection accuracy.
