Abstract
Oil depots along products pipelines are important components of the pipeline transportation system and down-stream markets. The operating costs of oil depots account for a large proportion of the total system’s operating costs. Meanwhile, oil depots and pipelines form an entire system, and each operation in a single oil depot may have influence on others. It is a tough job to make a scheduling plan when considering the factors of delivering contaminated oil and batches migration. So far, studies simultaneously considering operating constraints and contaminated oil issues are rare. Aiming at making a scheduling plan with the lowest operating costs, the paper establishes a mixed-integer linear programming model, considering a sequence of operations, such as delivery, export, blending, fractionating and exchanging operations, and batch property differences of the same oil as well as influence of batch migration on contaminated volume. Moreover, the paper verifies the linear relationship between oil concentration and blending capability by mathematical deduction. Finally, the model is successfully applied to one of the product pipelines in China and proved to be practical.

Refinery throughput is 76.8 9 106 bbl/d (BP 2014) and pipelines can provide an economic transportation mode for petroleum industries. In both producing and consuming countries, a large amount of oil products is transported from refineries or wharfs to oil depots through pipelines and pumped to downstream markets (Li et al 2015; Liang et al 2012a)
Summary
Oil products are still one of the major energy sources in industries, such as power generation, transportation, metallurgy, chemical industry and light industry. In both producing and consuming countries, a large amount of oil products is transported from refineries or wharfs to oil depots through pipelines and pumped to downstream markets (Li et al 2015; Liang et al 2012a). Oil depots connecting up-stream sources and down-stream markets, play a vital role in the entire transportation system (Duan et al 2016). Oil depots have large turn-round volume and complex operations. The delivery of contaminated oil to the down-stream stations is a systematic issue and the operation of each oil depot is interrelated with others
