that co2 emission may also play a major role in global warming. In recent times, there have been global environment concerns for the reduction of green house gas emissions from industrial sources, such as thermal plants, to alleviate the global warming problem. Generally, global warming results from the emission of methane, carbondioxide, nitrous oxide, chlorofluoro carbons (Daris and Cornwell 1991). Among these, co2 is considered to be the principal contributor to the problem, thus being the target of major reduction.
