庆哈输油管道热力计算模型研究

摘要

The long-distance pipeline in eastern China's main transport of high crude oil,less waxy crude oil at normal temperature fluidity,so often by heat transport processes. To ensure the safety of pipeline transportation of oil,at the same time be able to run the economy,you should study the thermodynamic properties of normal operating conditions of the pipeline,the establishment of the thermal model,along the pipeline using a model to calculate different conditions (different seasons,different transmission capacity, etc.) under the temperature,compared with the actual data,error analysis,summarize the distribution of temperature.%中国东部的长输管道主要输送高含蜡原油，含蜡原油在常温状态下的流动性较差，所以常采用加热输送工艺。为保证管道安全输送油品、同时能够经济运行，则应该研究正常运行工况下管道的热力特性，建立热力模型，使用模型计算不同工况（不同季节、不同输量等）下输油管道沿线的温度，与实际数据相对比，进行误差分析，总结温度的分布规律。
