Abstract:
Mineral carbonation of CO2 using coal fly
ash (CFA) is identified as a promising way of mitigating
carbon emissions safely and permanently with a low
material cost. However, the available literature has been
limited to laboratory scale studies. Thus, a process
simulation-based analysis was conducted using the
Aspen plus process simulation software for a large-scale
CO2 sequestration process from CFA. Carbonation
performance was analyzed against variation of several
process conditions while validating the developed
simulations with published experimental results.
Regarding multiple column arrangements for the scaledup
process, the simulation results showed that a parallel
arrangement would be more effective in both CO2
sequestration performance and economic aspects.
