摘要/Abstract

摘要： 当冷热原油交替输送时,如果混油温度低于其凝点则容易出现凝管现象,但是如果输送温度过高,虽然能保证输送安全,却极易造成能耗损失,因此有必要从节能及安全角度进行研究。通过CFD软件对混油段的温度场进行模拟,结合混油段凝点实验和长吉输油管线数据,与实验结果进行对比并找出了危险点,从而降低了冷油加热温度并达到了节能的目的。同时,给出了两种安全节能输送方案:俄油全程加热到10.0 ℃;只对油尾加热到30.0 ℃,加热长度为1380.8 m。进行经济对比分析的结果可知,第一种输送方案所需费用较传统输送方法可降低 91.54%,第二种输送方案所需费用较传统输送方法降低98.16%,第二种输送方案的节能效果优于第一种输送方案。研究结果对工业生产具有一定的指导意义。

Abstract: In the process of batch transportation, when the temperature of mixing oil is below the solidifying point, the pipeline is easy to be congelation. Although the high temperature could ensure the safety transportation, it could lead to the loss of energy consumption. Therefore, it was necessary to study the transportation from the point of energy saving and safety. Combined with the solidifying point of the mixed oil segment experiment and Changchun to Jilin pipeline,the mixed oil segment temperature field of cold and hot crude oil was simulated by CFD software. Compared with the experimental results, we found out the dangerous point, which reduced the heated temperature of cold oil and achieved the goal of energy conservation. At the same time, two kinds of transportation solutions of safety and energy conservation were given: The Russian oil was heated to 10.0 ℃ in the whole process；only the oil tail was heated to 30.0 ℃ with the heating length of 1 380.8 m. Through economic comparison, the cost of the first delivery scheme was reduced by 91.54% than the traditional transportation, the cost of the second transportation scheme was reduced by 98.16% than the traditional transportation cost, and the energy saving effect of the second transportation scheme was better than the first kind of transportation scheme，which had a certain guiding significance for industrial production．
