Innovative treatment of contaminated aviation kerosene during batch transportation of Zhenhai-Hangzhou Products Pipeline

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.
