- 摘要:
- 在区分可避免、不可避免热㶲损失的基础上,提出了热㶲利用率的定义,用以评价原油管道不同运行工况下的㶲耗状况,能够真正体现对热㶲的有效利用程度。以大庆某输油管道为例,计算原油管道在不同运行条件下的热㶲利用率,研究其随管径、原油输量、出站温度及保温层厚度等影响因素的变化情况,并采用正交实验分析法比较四种因素对管道热㶲利用率的影响程度。研究结果表明,四种因素对热㶲利用率影响程度由大到小依次是管径、原油输量、出站温度、保温层厚度,可为原油管道优化运行提供一定理论依据。
Based on differentiating the avoidable and inevitable heat exergy loss, heat exergy utilization is defined and used to evaluate the exergy consumption of crude oil pipeline under different working conditions, which can truly reflect effective heat exergy utilization level. A pipeline of Daqing oilfield is taken as an example, the heat exergy utilization of the crude oil pipeline under different operation conditions is calculated and analyzed, and the effects of pipe diameter, crude oil throughput, outbound temperature and insulation thickness on it are studied. The orthogonal experiments are made to compare the influence of the factors. The results show that influences of the four factors from high to low are pipe diameter, crude oil throughput, the outbound temperature and insulation thickness, which could provide certain theoretical basis for the optimal operation of crude oil pipeline.
