Implementation of Compact Carbon Capture Modules on Offshore Hydrocarbon Production Facilities

Abstract

Abstract Carbon capture and storage (CCS) have been successfully implemented onshore by different industries, including utilities and waste treatment, to capture the carbon dioxide (CO2) from the flue gases after the combustion of fossil fuels. To duplicate this success for offshore hydrocarbon processing facilities can be challenging due to the facility deck space constraints and marine environmental conditions. Innovative compact carbon capture modules for gas turbine (GT) exhaust gas CO2 capture have recently been developed taking these constraints into account for applications on large offshore oil and gas facilities such as Floating Production, Storage and Offloading (FPSO) facilities and Floating Liquefied Natural Gas (FLNG) facilities, as well as relatively smaller fixed-bottom platforms such as Central Production Platforms (CPPs). This paper describes the design of the compact carbon capture modules including the post-combustion CO2 removal process technology used, for applications on offshore facilities. A carbon capture system which removes CO2 using a proprietary amine-based solvent and absorption technique is powering these compact carbon capture modules. The described carbon capture module design is suitable for applications on new as well as existing offshore facilities. For implementation of the carbon capture modules on typical CPP and FPSO/FLNG facilities, the utility requirements and facility layout design are described in this paper. It is demonstrated that deploying amine-based carbon capture technology offshore is now feasible using these lighter-weight and smaller-footprint carbon capture modules, significantly reducing CO2 emissions from GT power generation systems.
