中国石油大学（华东）毕业设计（论文） AY-CHI输油管道的初步设计 学生姓名：秦光达 学 号专业班级：油气储运工程07-3班 指导教师：张足斌 2011年6月19日 摘要 高滨管线工程全长456.7km，年设计最大输量为1690万吨，最小输量为1014万吨。 管线沿程地形虽然较为曲折，最大高差为102m，但经校核全线无翻越点；在较大输量时可热力越站，较小输量时可压力越站。 全线共设热泵站4座，管线埋地铺设。管材采用，L415（X60）的钢管；采用加热密闭式输送流程，先炉后泵的工艺，充分利用设备，全线输油主泵采用串联方式，给油泵采用并联方式。加热炉采用直接加热的方法。管线上设有压力保护系统，出站处设有泄压装置，防止水击等现象，压力过大造成的危害。 首站流程包括收油、存储、正输、清管、站内循环、来油计量及反输等功能；中间站流程包括正输、反输、越站、收发清管球等功能。 绘图部分内容包括管道纵断面图(布站图)，首站工艺流程图，首站平面布置图，泵房安装图和中间热泵站工艺流程图。 关键词: 管道；输量；热泵站；工艺流程；运行方案 ABSTRACT The whole length of the pipeline is 265 kilometer and the terrain is plan.The maximum of transport capacity is 1700 million ton per year and minimum of throughout is 850 million ton per year. The choice of main equipment and determination of station site are based on the condition of every throughout. After the technical evaluation , one type of steel pipeline called L415(X60) is select. The optimum diameter is 720.0 millimeter and the wall thicket is 8millimeter. In order to reduce the loss of heat, the pipeline is buried under the ground. The pipeline is coated with 6-millimeter thick anti-corrosion asphalt layer. The process of transportation is pump-to-pump tight line operation. Crude oil is heated at first and the pump in each station. There are three HSB20?0?5 r pumps and one HSB20?0?9 pump coare equipped as the transporting pump. The process of flows in the station includes: collecting crude oil; forward transportation; reverse pumping over station and circulation in the station. Along the main line, oil transportation included head station, intermediate heating and pumping station, intermediate pumping station and terminal station.
