Deduction and Analysis of Driving Exergy Loss in Oil Pipeline System

Abstract:

Pipeline transportation is a substance conveying process that makes crude oil flowing from first station to ultimate station and at the same time takes a certain amount of driving energy for cost. Based on related theories of engineering fluid mechanics, mathematics analytic formula of driving exergy in oil pipeline transportation is deduced by micro-element analysis. We can get the conclusion that driving exergy loss has a positive correlation with diameter and throughput, and also a contrary trend with insulation thickness and outbound temperature by analyzing the influence on driving exergy loss from operation parameters in pipeline process,. This research can provide theoretical guidance for energy consumption classification, and further more, the technical support for energy consumption in pipeline system.
