Abstract:
Fossil-fuel power plants are the largest single source of carbon dioxide (CO2) emissions.
Post-combustion capture through monoethanolamine-based absorption is viewed as the
most mature technology proposed for mitigating CO2 emissions from such power
plants. Despite its advantages, several design and operational challenges arise in the
application of this technology. The amount of flue gas to process is much greater than
current applications. As a consequence, there will be a large thermal energy requirement
for solvent regeneration. There are also concerns about how post-combustion CO2
capture would affect the flexibility and operability of coal-fired power plants. Though
expensive pilot plant studies exist worldwide, they are still on a much smaller scale than
what would be required commercially. This thesis provides useful insights for the
design and operation of pilot and commercial plants through modelling and simulation. Cont/d.
