Exergy analysis of municipal solid waste incineration processes: The use of O2-enriched air and the oxy-combustion process

Giorgio Vilardi et al.

Summary: This work provides a complete exergy analysis of municipal solid waste incineration process, with considerations on increasing O2 %mol and adopting oxy-combustion conditions. Flue gas recirculation and oxygen-enriched air were found to improve exergy efficiency and reduce environmental impact. However, limited exergetic improvements were observed due to the exergy cost of the air separation unit.

A performance comparison study of five single and sixteen blended amine absorbents for CO2 capture using ceramic hollow fiber membrane contactors

Edoardo Magnone et al.

Summary: This study aimed to establish the relationship between the CO2 absorption properties of five single amine-based absorbents and their sixteen binary mixtures for CO2 chemical absorption, using a hydrophobic modified ceramic hollow fiber membrane contactor. The study found that MEA and DEA have the highest CO2 absorption flux among single amine solutions, while replacing MDEA with 20 wt% DEA can significantly increase CO2 chemical absorption in blended amine-based absorbents. Additionally, aqueous MDEA blended with DEA showed a over 500% increase in CO2 absorption flux compared to single MDEA solution.
