Abstract:
Increase in greenhouse effect in which more infra-red
radiations are getting trapped within the earth has been traced to fossil
fuel emissions. Among these emissions, carbon dioxide has been the
driving force behind this heating, currently standing at more than
380 ppmv and rising by 2 ppmv per year. Since fossil fuels continue
to form 80% of energy in the foreseeable future, efforts must be
sustained towards reduction of resulting greenhouse gases. Research
has shown that post combustion absorption using a suitable solvent
can reduce carbon emission from an exhaust stream. This research
involves developing a laboratory model of carbon capture technique
based on absorption in a packed bed column. Tests have shown that
increase in temperature, besides gas and liquid loading, facilitates
absorption of the CO2 gas.
