Globally, large private and public funds are invested into CO₂ capture and storage (CCS) research to provide the knowledge and technology required to mitigate CO₂ emissions below a sustainable level. A pertinent question to ask is whether this is the best way of spending limited resources. This pape...

A technical evaluation of CO₂ capture technologies when retrofitted to a cement plant is performed. The investigated technologies are the oxyfuel process, the chilled ammonia process, membrane-assisted CO₂ liquefaction, and the calcium looping process with tail-end and integrated configurations. For...

This paper presents an assessment of the cost performance of CO₂ capture technologies when retrofitted to a cement plant: MEA-based absorption, oxyfuel, chilled ammonia-based absorption (Chilled Ammonia Process), membrane-assisted CO₂ liquefaction, and calcium looping. While the technical basis for ...
