Carbon dioxide (CO2) has been identified as the most significant
greenhouse gas arising from anthropogenic activities. Presently,
atmospheric levels of CO2 are thought to be about 25% higher than in
pre-industrial times [1]. It is of great importance to reduce
anthropogenic CO2 emissions in order to counteract global warming.
In many countries (7 in the EU) a tax related to CO2 emissions has
been introduced in order to encourage better plant efficiency and/or
create increased investment in CO2 mitigation. One method of
accomplishing a reduction in CO2 emissions is fuel switching. As an
example, if naphtha is used as a fuel, the following combustion
reaction takes place:
