Abstract
Disclosed herein are combustion systems, power plants, and flue gas treatment systems that incorporate sweep-based membrane separation units to remove carbon dioxide from combustion gases. In its most basic embodiment, the invention is a combustion system that includes three discrete units: a combustion unit, a carbon dioxide capture unit, and a sweep-based membrane separation unit. In a preferred embodiment, the invention is a power plant including a combustion unit, a power generation system, a carbon dioxide capture unit, and a sweep-based membrane separation unit. In yet another embodiment, the invention is a flue gas treatment system that incorporates three membrane separation units with a carbon dioxide liquefaction unit.
