等温输油管道的工艺计算与运行管理 摘要 管道输送是原油、成品油及天然气长距离运输的主要方式。一般通过工艺计算确定: 输油参数。等温输油管道的工艺计算已作为其他各种管道输送方式的计算基础，等温输 油管道的工艺计算包括有：水力计算和管道厚度计算。本文涉及的工艺计算是使用已给 定了主要的工艺设计参数，利用相关公式通过水力计算以及其他计算方法确定本次工艺 计算所需要的参数：泵站数、站址、以及各站进、出站压力。等温输油管道在正常工作 时，全管线基本处于运行参数相对最佳的稳定运行状态，当有时有计划的调整参数或者 一些突发事故原因，都会可能引起运行工况的变化。不论是正常工况变化还是事故工矿 变化，都要加以控制调节。在本论文中运行管理部分主要分析了某中间站停运后的工况 变化和干线漏油后的工况变化，以及输油泵与管路系统的调节。 关键词：等温输油管道；工艺计算；工况变化；水力计算；运行管理。 Processcalculationofisothermaloilpipelineandoperation management Abstract:Pipelinetransportation of crude oil,themain form of long-distancetransportation of refined oil and natural gas. The oil parameters are generally determined through process calculation.Processcalculation ofthetemperaturepipelineprocesscalculation ascalculated on the basis of various other pipeline, isothermal pipeline include:hydraulic calculation and pipe thicknesscalculation.Processcalculationsinvolvedinthispaperhasidentifiedthemainprocess design parameters, using the relevant formula by hydraulic calculation and other calculation methods to determine the process calculation parameters: the number of pumping stations, station site, as well as the station into the station pressure. During the isothermal pipeline is normal operation, the whole pipeline in the basic operating parameters relative steady state, when sometimes there are plans to adjust the parameters or some unexpected cause of the accident will cause changes in operating condition. Both normal operating conditions change, and accident, industrial change,must be controlledto adjust.In thispaper mainly analyzesthe operating conditions change after the oil spill of the operating conditions change in a middle stationoutageandtrunk,andtheregulationofthepumpandpipingsystems.
