摘要
以仪征至金陵石化输油管道为例,从点炉临界条件、停炉临界条件的确定以及仪征站最佳出站油温的计算和最大安全停输时间的计算四个方面,介绍了热油管道在不饱和输送工况下如何节能运行需要着重考虑的几个因素,并从仪金管道大量停输数据中反算出确定该段管道特性的总传热系数(K)的取值方法。
Take the Yizheng-Jinling Oil Pipeline as an example,this article introduces the energy saving running for the hot oil pipeline under the condition of low throughput operation from 4 facets: (1) determination of critical condition of heater start-up; (2) determination of critical condition of heater shutdown; (3) calculation of optimized outlet oil temperature from Yizheng Station and (4) calculation of maximum safe shutdown time of the pipeline. The determination method of total heat transfer coefficient of this pipeline section is given on the basis of inversion calculation from the shutdown data of the pipeline.
