A Study of Very Large Scale Post Combustion CO2 Capture at A refining & Petrochemical Complex

Publisher Summary This chapter presents a study of the CO2 Capture Project (CCP), which is a joint project of eight major energy companies working to make significant reductions in the cost of capturing and storing CO2. The CCP is developing a range of technologies including post-combustion, oxyfuel, and pre-combustion decarbonization. The study aims to review the cost and practicability of capturing CO2 from the site using today's best available technology. The study examines issues of retrofitting a very large scale, post combustion, amine based capture facility, which is designed to capture 2,000,000 tonnes per annum of carbon dioxide which is compressed to 220 bar(a) for pipeline transmission to a North Sea oil field where it is used for Enhanced Oil Recovery. The study provides a firm basis for comparison with other technologies and develops a feasible process design and cost estimate. The study demonstrates that, despite the unprecedented scale, the post combustion capture of 6,000 tonnes per day of carbon dioxide from a range of process heaters and boilers across a refinery and petrochemical complex is technically feasible, using today's best available technology.
