Membrane technologies for CO2 separation
Journal of Membrane Science, 2010Today, all the existing coal-fired power plants present over the world emit about 2 billion tons of CO2 per year. The identification of a capture process which would fit the needs of target separation performances, together with a minimal energy penalty, is a key issue.

Among various CO2-capture technologies, membrane separation is considered as one of the promising solutions, because of its energy efficiency and operation simplicity. Many research and development are conducted for the (1) CO2/N2 (post-combustion: CO2 separation from flue gas), (2) CO2/CH4 (CO2 separation from natural gas), and (3) CO2/H2 (pre ...

CO2 separation during hydrocarbon gasification
Energy, 2005Abstract Hydrocarbon can be gasified with steam into fuel gas, including CO, CO 2 , H 2 , CH 4 , etc. For H 2 production, it is necessary to separate the other gases from hydrogen. In this study, hydrogen production by removal of carbon oxides during hydrocarbon gasification with CaO and other metal oxides was examined theoretically and ...

AlPO-18 membranes for CO2/CH4 separation
Chemical Communications, 2012The synthesis of reproducible and continuous AlPO-18 membranes is demonstrated. The separation performance of these membranes for equimolar CO(2)/CH(4) gas mixtures is presented. The AlPO-18 membranes displayed CO(2) permeances as high as ~6.6 × 10(-8) mol m(-2) s Pa with CO(2)/CH(4) separation selectivities in the ~52-60 range at 295 K and 138 kPa.

CO2-tolerant oxygen separation membranes targeting CO2 capture application
Journal of Membrane Science, 2009Abstract Burning fossil fuels with O2/CO2 mixture produces a concentrated CO2 stream and thus enables efficient CO2 capture. In an attempt to improve the economic competiveness of this oxy-fuel combustion technology, intensive efforts have been made to develop ceramic oxygen separation membranes that have a potential to reduce the oxygen production ...

Steam-promoted CO2 flux in dual-phase CO2 separation membranes
Journal of Membrane Science, 2015Abstract Steam dissolving into molten carbonates through the formation of hydroxide ions could contribute to the permeation of CO 2 in dual-phase membranes under certain conditions. In this work, ceria (CeO 2 ) supported dual-phase membranes was fabricated and the effect of steam on the transport properties has been investigated by means of flux ...

Sizing Separators for CO2 Flood Operations
SPE Annual Technical Conference and Exhibition, 1982ABSTRACT The design of field separation equipment under CO2 flood operations requires that many variables be addressed. During a CO2 flood, separators will be required to effectively separate large volumes of multi-component gas streams from produced oil and water.

H2 Production and CO2 Separation
2011A promising technology for H2 production and CO2 separation is based on water gas shift reaction operated in water gas shift membrane reactor (WGSMR). In such a reactor the synthetic gas reacts with steam in a catalytic bed to produce additional hydrogen and CO2.
