油气管道总传热系数的计算与分析
|
摘要
油气管道的总传热系数(OHTC)是体系管道热流量的重要参数,对于管道热力计算和后期运行状态监控至关重要。为了解决设计阶段依据规范和手册的可参考值有限以及现有工艺分析软件在模型描述上存在不足等问题,根据热阻原理分析了设计过程中常用管道模型的总传热系数计算方法,编制了具备常见模型模块和自定义模块的OHTC计算软件,该计算软件提高了油气管道总传热系数的计算精度,简化并完善了设计计算。
The overall heat transfer coefficient(OHTC)of oil &gas pipelines is a significant permanent to reflect the heat flow of the pipe.It's quite crucial for pipe thermodynamic calculation and monitoring the later operation state.In order to deal with the problems present to the design process,such as the limited referable value(according to the present specifications & manuals)and incomplete model description in process analysis software,etc.,the paper analyzed the calculation method of OHTC of several frequently used pipe models based on principle of thermal resistance,and programed the OHTC Calculation Tool which is qualified with the normal model modular and custom model modular.The OHTC Calculation Tool can improve the calculation precision of OHTC and simplify the calculation process.Besides,related suggestions on choosing OHTC of oil &gas pipelines have also been proposed.
