二氧化碳脱水和管道输送技术分析-analysis of carbon dioxide dehydration and pipeline transportation technology.docx

摘要环境问题是 21 世纪人类可持续发展所面临的重要问题，其中温室效应是最大 的环境问题之一，已引起人们 的广泛关注。目前，将工业尾气中的 CO2 捕集并加 压封存至海洋或陆地，或者将其纯化用于提高原油采收率（ EOR）是缓解温室效 应的有效手段。CO2 脱水和输送是联系捕集和封存与利用的中心环节，对整个过 程有着重要的作用。本文以国家科技支撑项目为依托，对捕集的 CO2 进行了脱水工艺研究，并对CO2 输送技术及 CO2 管道工程设计方案进行研究。关键词：二氧化碳；三甘醇脱水；Aspen plus；管道输送技术；管道工程设计AbstractEnvironmental problem is an important issue faced by humankind in sustainable development. The greenhouse effect is listed as one of the biggest environmental problems in the 21st century and has caused wide public concern. At present, it is an effective way to alleviate the greenhouse effect by capturing the CO2 from industrial exhaust gas and storing it in the ocean or enhancing oil recovery (EOR). CO2 dehydration and transportation are the central parts of CO2 capture storage and use, and play an important role in the whole process.In this paper, based on national science and technology support project, the dehydration process was studied for the capture of CO2, and CO2 transportation technology and CO2 pipeline engineering design have been analyzed here as well.Keywords: Carbon dioxide; Triethylene glycol dehydration; Aspen plus; Pipe transportation technology; Pipeline engineering design目录湖南大学学位论文原创性声明和版权使用授权书 ..................................................
