Abstract: This paper summarizes the results obtained in Nanoglowa EU project using polymeric polyvinylamine fixed site carrier membranes developed at NTNU Norway for CO 2 removal from flue gas. The pilot scale testing using real flue gas was performed at Sines power plant of EDP in Portugal. The aim of the project was CO 2 separation from flue gas of coal fired power plants using membrane technology and involved several aspects: membrane up-scaling, material durability and pilot testing in a power plant. Gas permeation experiments and material analyses confirmed that the membrane material and separation performances were not affected negatively by exposure to synthetic and real flue gas contaminants. A pilot scale module having installed a 1.5 m 2 of NTNU membrane was tested continuously for 6,5 months. The membranes showed constant separation performances with a maximum content of 75% CO 2 in permeate and a permeate flow of 525 l/day. The performances were kept constant despite several challenges related to power plant operation such as high levels of NOx (600 mg/Nm 3 ) and 200 mg/Nm 3 SO 2 , and frequent power plant outages.
