Carbon filter process for flue-gas carbon capture on carbonaceous sorbents / Bryce Dutcher in Industrial & engineering chemistry research, Vol. 50 N° 16 (Août 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 16 (Août 2011) . - pp. 9696-9703 Titre : Carbon filter process for flue-gas carbon capture on carbonaceous sorbents : steam-aided vacuum swing adsorption option Type de document : texte imprimé Auteurs : Bryce Dutcher, Auteur ; Hertanto Adidharma, Auteur ; Maciej Radosz, Auteur Année de publication : 2011 Article en page(s) : pp. 9696-9703 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Vacuum  swing  adsorption  Water  vapor  Gaseous  effluent Résumé : A low-pressure carbon filter process can capture carbon dioxide from combustion flue gas. This filter is filled with a carbonaceous sorbent, such as activated carbon, which has a high chemical affinity to and hence high capacity to retain CO2 but not nitrogen. This in turn leads to a high CO2/N2 selectivity, especially at low pressures. While CO2 sorption is spontaneous and rapid, its recovery from the sorbent is a challenge that determines the process efficiency. Among the desorption methods considered in this work, direct steam can produce nearly pure CO2, but it results in condensed water in the bed that reduces the sorbent capacity and requires sorbent cooling, which is slow. Vacuum desorption in the absence of water also works, but it requires low pressures, much lower than 30 Torr, to achieve substantial CO2 yields. However, a hybrid approach, referred to as "steam-aided vacuum swing adsorption" (SA-VSA), proposed in this work, is found to alleviate or eliminate these problems. Water vapor serves as a displacement medium and hence increases the vacuum efficiency at moderate pressures. Vacuum, on the other hand, prevents bulk water condensation and sorbent heating, and hence eliminates the need for cooling. As a result, SA-VSA can completely recover nearly pure CO2 from combustion flue gas, but it also allows for optimizing the CO2 recovery and purity.

Flue-Gas Carbon Capture on Carbonaceous Sorbents: Toward a Low-Cost Multifunctional Carbon Filter for “Green” Energy Producers / Maciej Radosz in Industrial & engineering chemistry research, Vol. 47 N°10 (Mai 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 N°10 (Mai 2008) . - p. 3783–3794 Titre : Flue-Gas Carbon Capture on Carbonaceous Sorbents: Toward a Low-Cost Multifunctional Carbon Filter for “Green” Energy Producers Type de document : texte imprimé Auteurs : Maciej Radosz, Auteur ; Xudong Hu, Auteur ; Kaspars Krutkramelis, Auteur Année de publication : 2008 Article en page(s) : p. 3783–3794 Langues : Anglais (eng) Résumé : A low-pressure Carbon Filter Process (patent pending) is proposed to capture carbon dioxide (CO2) from flue gas. This filter is filled with a low-cost carbonaceous sorbent, such as activated carbon or charcoal, which has a high affinity (and, hence, high capacity) to CO2 but not to nitrogen (N2). This, in turn, leads to a high CO2/N2 selectivity, especially at low pressures. The Carbon Filter Process proposed in this work can recover at least 90% of flue-gas CO2 of 90%+ purity at a fraction of the cost normally associated with the conventional amine absorption process. The Carbon Filter Process requires neither expensive materials nor flue-gas compression or refrigeration, and it is easy to heat integrate with an existing or grassroots power plant without affecting the cost of the produced electricity too much. An abundant supply of low-cost CO2 from electricity producers is good news for enhanced oil recovery (EOR) and enhanced coal-bed methane recovery (ECBMR) operators, because it will lead to higher oil and gas recovery rates in an environmentally sensitive manner. A CO2-rich mixture that contains some nitrogen is much less expensive to separate from flue-gas than pure CO2; therefore, mixed CO2/N2-EOR and CO2/N2-ECBMR methods are proposed to maximize the overall carbon capture and utilization efficiency.

An ammonium cation with short alkyl group, BF4 anion, and polystyrene backbone was found to favor CO2 sorption in PILs. CO2 sorption in the PILs fitted the dual-mode model very well, suggesting that the CO2 sorption consists of dissolution in the polymer matrix and Langmuir sorption in the microvoids.
