Evaluation of the Performance and Economic Viability of a Novel Low Temperature Carbon Capture ProcessLychnos, George; Clements, Alastair; Willson, Paul; Font Palma, Carolina; Diego, Maria E.; Pourkashanian, Mohamed; Howe, Joseph; PMW Technology Limited; University of Sheffield; University of Chester (SSRN, 2018-10)A novel Advanced Cryogenic Carbon Capture (A3C) process is being developed due to its potential to achieve high CO2 capture efficiencies using low cost but high intensity heat transfer to deliver a much reduced energy consumption and process equipment size. These characteristics, along with the absence of process chemicals, offer the potential for application across a range of sectors. This work presents a techno-economic evaluation for applications ranging from 3% to 30% CO2 content.
Experimental Exploration of CO2 Capture Using a Cryogenic Moving Packed BedCann, David; Willson, Paul; Font Palma, Carolina; University of Chester; PMW Technology Ltd; University of Chester (SSRN, 2018-10)This study examines a novel cryogenic post-combustion capture process, based on a moving bed of cold beads to freeze CO2 out of a flue gas, and this paper presents the first steps in experimental work. The preliminary experiments included the test of fluidization of bed material, if the flow rate of bed material can be kept constant in and out of the column and the estimation of heat transfer coefficient. The obtained results are encouraging for the running of the rig at cryogenic conditions.
Production of Biomethane from Agricultural Waste Using a Cryogenic Carbon Capture ProcessFont Palma, Carolina; Lychnos, George; Willson, Paul; University of Chester; PMW Technology Limited (Energy Proceedings, 2019)This paper evaluates a novel cryogenic carbon capture process to upgrade biogas produced from agricultural waste. The A3C cryogenic process offers simplicity and compactness with lower capital and operating costs compared to many alternative processes. The work addresses potential technical issues presented by trace contaminants in the raw biogas including hydrogen sulphide, organics and siloxanes. It is found that the A3C process offers high CO2 removal with minimal biomethane losses while requiring simple raw gas treatment.
