摘　　要：对两路汽油、煤油、柴油等特种油品进行在线全馏程分析的实现进行了研究。分析仪的分析原理完全按照标准蒸馏法实验方法进行设计,双核同步分析两路油品的全馏程,并具备大气压力补偿环节。样油经预处理脱水除杂降温后,按照标准蒸馏法测量并记录完整的蒸馏过程,得到详细的样品蒸馏曲线。完成分析的样品通过回收系统的处理再返回工艺管线。分析的数据和仪表故障报警信号可随时上传,实现远程监控。介绍了分析仪的操作事项,总结了分析仪的技术特点。系统经过实验给出样油的初馏点和终馏点分析结果的统计与趋势图,验证了系统的精度。The realization of on-line full range analysis for special oil such as gasoline,kerosene and diesel is studied.The principle of analyzer is completely designed in accordance with the standard distillation experiment method.The two-core simultaneous analysis of the whole distillation range of two oil products and the atmospheric pressure compensation link is established.The sample oil is pretreated,dehydrated,mixed,cooled and measured in accordance with standard distillation method.A detailed sample distillation curve is obtained.The sample completed the analysis is processed by the recycling system and then returned to the process pipeline.The analysis data and the instrument fault alarm signal can be uploaded at any time to achieve remote monitoring.The operation items of analyzer are introduced.The technical characteristics of analyzer are summarized.Through experiments,the system gives the statistics and trend diagram of the initial boiling point and final boiling point of the sample oil,and the accuracy of the system is verified.
