Absorption based processes applying phase transition for energy efficient postcombustion CO2 capture
… 30 wt% monoethanolamine (MEA) solvent for postcombustion CO2 capture, is energy intensive and thus costly. The novel phase transitional CO2 absorption process has been regarded as a promising alternative to the benchmark MEA process. The solvent in a phase transitional process turns into …

CO2-Abtrennung aus Gasströmen durch Absorption in Poly(methyldiglykol)amin
… neu entwickelten Waschmittels GenosorbN in einem Postcombustion-Prozess einen geringeren Energiebedarf als bisher bekannte Verfahren aufweist. Für die Nachrüstung bereits vorhandener Kraftwerke ist der Postcombustion-Prozess vorteilhaft, da er im Vergleich zum IGCC- oder dem Oxyfuel-Verfahren die …

Efecto del vapor de agua en la adsorción de CO2 postcombustión
… a high CO₂ capture performance, particularly in postcombustion capture applications, has been very intensive. Within this context, it is of the utmost importance to evaluate the performance of the adsorbents under humid conditions and in the presence of other pollutants in the gas stream so as to …

Processing of high-sulfur coals using microbubble column flotation
… a leading contributor to acid rain. A number of postcombustion techniques for the reduction of sulfur dioxide emissions are being tested; however, the reduction in the pyritic sulfur content of coal through physical cleaning methods may be the most economically viable alternative to the S02 …

Charged interfaces and their applications in energy sustainability
… waterbodies, harming the local ecosystem. In postcombustion CO₂ capture systems, the absorption of CO₂ from flue gas into a sorbent liquid is capital expensive. The need for large surface area of interaction necessitates the installation of prohibitively expensive absorption towers and the …

Amine-mediated electrochemical reduction of CO₂ in a nonaqueous, Li-CO₂ battery/
… a combined chemical-electrochemical device for postcombustion capture and subsequent conversion of CO₂ into a benign, solid alkali metalcontaining phase (lithium carbonate, Li2CO₃). The capture is accomplished in a non-aqueous battery electrolyte containing a molecular CO₂ sorbent, and the …

Pilot-Scale Evaluation Of Advanced Solvents For CO2 Capture From Coal-Fired Utilities
… for their removal of CO2. For the case of postcombustion capture, the main conclusions are that 90% CO2 capture can be met with MEA and advanced solvents. The EERC system was able to capture at least 90% of the CO2 present in the flue gas for each advanced solvent and the baseline MEA. …
