摘　　要：为解决车用柴油升级导致镇杭管道顺序输送产生的航煤混油无法处理的难题,结合生产现状,创新性地提出并实施两套可同时进行的方案,即可暂时解决问题的混油调和降级处理方案和可长远解决问题的低硫航煤隔离输送项目改造方案。前者将航煤混油与车用柴油按1∶3的质量比调和,并降级成普柴处理,可暂时解决混油无法处理的难题,有效缓解罐容压力,但效益损失较大。后者采用硫含量低于10 mg/kg的低硫航煤作为航煤的油头和油尾隔离输送,产生的低硫混油直接回掺至车用柴油罐,无需再另罐储存。低硫航煤隔离输送航煤的工艺,在不改变一管多用的前提下,彻底解决了航煤混油处理难题,每年减少效益损失逾2 000×104元,对成品油管道顺序输送航煤混油的处理具有借鉴意义。It is difficult to treat the contaminated aviation kerosene which is generated in the batch transportation of Zhenhai-Hangzhou Pipeline due to the upgrading of automotive diesel. In order to solve this problem, two innovative plans which can be implemented simultaneously were proposed based on the production status. One is the blending and degradating treatment plan for contaminated aviation kerosene which can solve the problem temporarily. And the other is the transformation plan of low-sulfur aviation kerosene isolation transportation and it can solve the problem in the long term. In the former plan, the contaminated aviation kerosene is degraded into general diesel fuel after being blended with the automotive diesel in the mass proportion of 1：3.Thus, the treatment difficulty of contaminated aviation kerosene can be settled temporarily and the tank pressure can be alleviated effectively, but a large amount of benefit is lost. In the latter plan, the low-sulfur aviation kerosene （sulfur content〈10 mg/kg） is used as the head and tail for isolation transportation, and the contaminated low-sulfur aviation kerosene is flown back directly into the automotive diesel tanks instead of being stored in a tank separately. By means of low-sulfur aviation kerosene isolation transportation technology,treatment difficulty of contaminated aviation kerosene is solved completely and the benefit loss is reduced by more than twenty million yuan each year while the the premise of one pipe for multiple purposes is kept. The research results can be used as the reference for the treatment of contaminated aviation kerosene during batch transportation of products pipelines. （3 Figures, 1 Table, 17 References）
