Flue Gas - an overview | ScienceDirect Topics

The flue gas enters the lower part of the desulfurization absorption column under the action of the booster fan after being dusted by the dust collector. In the rising process, it comes into full contact with the falling limestone slurry sprayed by the spray. SO 2 in the flue gas is absorbed by the slurry and falls into the slurry pool at the bottom of the column.

Natural gas - Wikipedia

Natural gas (also called fossil gas; sometimes just gas) is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and

Climate change mitigation - Wikipedia

Climate change mitigation consists of actions to limit global warming and its related effects.This involves reductions in human emissions of greenhouse gases (GHGs) as well as activities that reduce their concentration in the atmosphere.. Fossil fuel combustion accounts for 89% of all CO 2 emissions and 68% of all GHG emissions. The most important challenge is to eliminate the use of coal, oil
