Abstract: In order to more accurately track oil batch interface in the oil products pipeline transportation, an oil batch interface tracking model with consideration of pipeline oil temperature changes is built and solved on the basis of solving oil temperature distribution along the pipeline. This model is used in Southwest Products Pipeline to compare the results of oil batch interface tracking considering temperature effects and those not considering temperature effects. The results show that the batch interface tracking model considering pipeline temperature effects is closer to the actual situation. It is recommended to pay attention to the changes of pipeline temperature for oil batch interface tracking.
