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.
