With renewed interest in enhanced oil recovery (EOR) as existing fields become depleted, there is renewed interest in supplying CO2 for flooding by CO2 recovery from flue gas. This paper examines key design and operating issues and trends for new unit designs which hold the potential for reducing the plant investment and operating costs associated with this source of CO2. The emphasis is on conventional processes using chemical solvents for CO2 removal (such as Fluor Daniel＇s ECONAMINE FG(SM) process) as these are either commercial or have been successfully pilot tested. Developments in new tower packings and solvents and their potential impact on plant and operating costs are discussed, as are the effects on these costs of the flue gas source. Operating and capital recovery cost data are provided for 1.000 tonne/d plants which would be a typical size for an EOR project.
