Abstract

In the process of crude oil pipeline transportation, if the transportation volume is lower than the minimum allowable pipeline transportation, the pipeline will increase the operation economy due to the increase in energy consumption, and the transportation process is not conducive to the efficient operation of equipment. Intermittent transportation is the main means to solve this problem, but the process is affected by pipeline throughput and intermittent time. In order to rationally distribute the pipeline hourly throughput and determine the intermittent time to reduce the pipeline energy consumption, a crude oil pipeline intermittent transportation optimal operation model is proposed in this paper. The model innovatively considers the pipeline shutdown time constraint and pipeline flow constraint and establishes the minimum energy consumption optimization model of crude oil pipeline intermittent transportation. Taking an oil pipeline in China as an example, the optimization model is solved by the FPA algorithm. After optimization, the energy consumption of the pipeline is reduced by 44% compared with the longest shutdown time and 18% compared with the shortest shutdown time.
