✦ Synopsis
The autlkrs have conducted a series of basic experiments for CO, removal from the flue gas of thermal power plants by use of hollow-fibre gas-liquid con&tom It was confiicd that the stability of PTFE membrane having a high degree of hydrophobic&y is more than 6,600 hours and that by improvin4 the de the durability an lr= of hydrophobicity on the surface of the membrane, performance of the membrane can be improved. They coofhcd that flow chtuacteristics of fluid in hollow-fibre can be estrmated based on Hageo-Poiscuilic law. The overall volumetric mass transfer coefficient Ka(=Kxa) of the hollow-fibrc gas-liquid contactor is more than 5 times larger than that of a conventional packed bed, which suggests that adoption of the present method has the advantage of making the absorber more compact. 9Sl02006 Thr COI l torago l fficloncy of aqulfrra yly e; Mcer, L G. Energy Convers. Mgmf., Jun.-Sep. 1995, 36, (6), Previous' work on the technical feasibility, limiting geological conditions and consequences of carbon dioxide storage in aquifers demonstrated that CO, storage in aquifers is a realistic option. At the 'First International Conference on Carbon Dioxide Removal' held in Amsterdam on the 4-6 March 1992, it was reported that the volumetric CO, sweep efficiency for a given representative aquifer was in the order of 3%. The main objective of that study was to investigate the tech&al possibility and limitations of CO, storage ln aquifers, not to fmd the maximum stars e efficiency (or volumetric sweep efficiency). The paper presents TNO'S 6-N 0 Institute of Applied Geoscience, Delft, The Netherlands) present view on the COJ water displacement process.
