Summary: | Sequestration projects are attempting to prevent the release oflarge quantities of C02
into the atmosphere from fossil fuel use in power generation and other industries by
capturing C02, transporting it and ultimately, pumping it into underground geologic
formations to securely store it away from the atmosphere. It is a potential means of
mitigating the contribution of fossil fuel emissions to global warming. The process is
based on capturing carbon dioxide (C02) from large point sources, such as fossil fuel
power plants, and storing it where it will not enter the atmosphere.
The interactions of C02 with coal will be investigated under a set of conditions to
determine the effects of the nature of the coal and the sequestration environment
including parameters such as rank and moisture content of the coal, the temperature,
and pressure, And the effect of these parameters on the C02 adsorption capacity.
Some sets of experiments are conducted based on the coal collected from two
different basins across Malaysia and the best isotherm obtained based on the best
adsorption capacity is selected to be the major basin where the carbon dioxide gas is
to be sequestrated.
Adsorption experiments were favorable at high pressure and low temperature
conditions and the Temkin isotherm was selected to represent the adsorption
behavior. |
