1、摘要天然气是优质、高效、清洁的能源和化工原料,在支持国民经济可持续发展、改善人民生活水平和保护环境方面已开始发挥越来越重要的作用。作为天然气开发和利用的纽带,管道已成为中国天然气输送的主要方式之一。但天然气管道的建设投资越来越大,输送距离越来越长,自动化程度要求也越来越高,这就要求建立完善输气管网。本设计主要进行兰州到银川输气管道首站工艺设计。其主要内容包括三部分:说明部分、计算部分和绘图部分。在说明部分,主要介绍了工程概况、设计方案比较与选择、压气站布置、管道材料选择、输气管道运行与管理、辅助生产设施和输气管道存在的问题及改进意见;在计算部分,主要计算管径、水力计
2、算、布站计算、压缩机和驱动机选型、确定工作参数及校核、末端储气量计算、管道强度校核;在绘图部分,绘制了沿程压降图、压气首站平面布置图和压气首站流程图。本次设计根据地形地貌、地理位置、管道长度、管道的年输量、天然气组分、沿线年平均地温及水文地质等情况,运用输气管道基本理论和基本原理,进行水力计算、经济计算并加以分析,最终确定输气站布置的最优方案。关键词:输气管道,设计,天然气,方案,末站AbstractNaturalgasasaclean,high-effectandhigh-qualityenergychemicalrawmaterials,insupportofs
