Report: Kingsnorth E.ON UK Carbon Capture & Storage Front End Engineering and Design (FEED) - Chapter 05: Technical Design-Carbon capture and compression plant

During 2010-11, as part of the Carbon Capture & Storage (CCS) Demonstration Competition process, E.ON undertook a Front End Engineering Design (FEED) study for the development of a commercial scale CCS demonstration plant at Kingsnorth in Kent, South East England. The study yielded invaluable knowledge and the resulting material is available for download here. This chapter presents the FEED stage Capture and Compression plant technical design. The 'Design Basis for CO2 Recovery Plant' lists the design parameters relating to the capture plant site, the flue gas to be treated, the utilities available, the required life and availability of the plant, and other constraints to be complied with in the capture plant, dehydration and compression design. The details of the processes of capture, compression, and dehydration are best visualised on the Process Flow Diagrams (PFDs) which show the process flows described above together with additional detail of coolers, pumps, and other plant items. Separate PFDs are provided for the capture plant, the compression plant, and the dehydration plant to show the complete flue gas and CO2 flows. Some of the key aspects of the technical design of the Capture and Compression plant are; There are two separate water circuits shown in the quencher with separate extractions of excess water. These have been separated because the recovered quench water is of good enough quality for re-use on the power station, whilst the deep FGD waste water is sent to the water treatment plant; Molecular sieves have been selected as the most appropriate equipment for dehydration of the CO2 prior to pipeline transportation; With the particular layout constraints of the Kingsnorth site, a split layout of the absorption and regeneration equipment is preferred over the compact layout.

在2010-11年间，作为碳捕集与封存（CCS）示范竞赛流程的一部分，E.ON公司对位于英格兰东南部肯特郡金斯诺斯的商业规模CCS示范工厂进行了前端工程设计（FEED）研究。该研究积累了宝贵的知识，相关资料可在此下载。本章阐述了FEED阶段的捕集与压缩工厂技术设计。‘二氧化碳捕集工厂设计基础’列出了与捕集工厂场地、待处理的烟气、可用的公用设施、工厂所需的使用寿命和可用性以及捕集工厂、脱水与压缩设计需遵守的其他限制相关的参数。捕集、压缩和脱水的具体过程可通过流程流程图（PFDs）进行最佳可视化，这些图展示了上述描述的过程流程，以及冷却器、泵和其他工厂设备的额外详细信息。为展示完整的烟气及二氧化碳流动，提供了捕集工厂、压缩工厂和脱水工厂的单独PFD。捕集与压缩工厂的技术设计中的关键方面包括：在淬火器中展示了两个独立的水回路，并分别提取多余的水。这是由于回收的淬火水质量足够高，可在电站中再次使用，而深液相脱硫废水则被送往水处理厂；选择了分子筛作为二氧化碳在管道运输前脱水的最适宜设备；鉴于金斯诺特场地的特定布局限制，相较于紧凑布局，更倾向于采用吸收与再生设备的分割布局。第五章节的《关键知识参考手册》的进一步支持性文件也可下载。请注意，此数据集是国家档案馆所保存报告的副本，可通过以下链接获取 - http://webarchive.nationalarchives.gov.uk/20121217150421/http://decc.gov.uk/en/content/cms/emissions/ccs/ukccscomm_prog/feed/e_on_feed_/technical/technical.aspx
