【摘要】：准确描述管道输送用能过程并科学构建其能耗评价指标体系,是原油管道能效管理的重要基础工作之一。目前,原油管道的用能计算与分析统计、工艺方案优化及能耗评价,一般侧重于供能站而非消耗能量的管段本身,且未对有效耗能与无效耗能进行区分,将能耗与能损完全等同,不利于管道系统节能的进一步研究。将传递用于管输过程的用能描述与能耗评价,强调能的真正价值,侧重于对管段本身有效耗的作用机理分析,补充并扩展了传统能耗评价指标体系。结果表明:在管输过程的总耗中,有效耗占85%以上,其中有效热耗相比有效压耗占了绝大部分,因此,原油管道输送节能的重点应该集中在如何降低热能消耗。研究结果为原油管道的安全经济运行提供了有益的理论依据和技术支持。
[Abstract]:It is one of the important basic work of energy efficiency management of crude oil pipeline to describe accurately the process of energy consumption in pipeline transportation and to scientifically construct the index system of energy consumption evaluation.At present, the calculation and analysis of energy use, the optimization of process plan and the evaluation of energy consumption of crude oil pipeline are generally focused on the energy supply station rather than the energy consuming section itself, and there is no distinction between the effective energy consumption and the ineffective energy consumption.Energy consumption is equal to energy loss, which is not conducive to further research on energy saving of pipeline system.In this paper, the energy consumption description and energy consumption evaluation of pipe transmission process are described, the real value of energy is emphasized, and the mechanism of effective consumption of pipe section is analyzed, which complements and expands the traditional energy consumption evaluation index system.The results show that the effective consumption accounts for more than 85% of the total consumption in the pipeline transportation process, in which the effective heat consumption is more than the effective pressure consumption. Therefore, the emphasis of energy saving in the pipeline transportation of crude oil should be focused on how to reduce the heat energy consumption.The results provide useful theoretical basis and technical support for the safe and economical operation of crude oil pipeline.
