Postcombustion CO2 capture with aqueous monoethanolamine (MEA) scrubbing is one of the most promising and wellproven techniques for reducing CO2 emissions into the atmosphere. However, this process has a critical problem: the high reboiler heat energy requirement for solvent regeneration at the stripper reboiler. To reduce the reboiler heat requirement, this paper suggests a new stripper ...

When coal is burned, the sulfur combines with the oxygen in the combustion air to produce SO 2, which is emitted into the air through a plant's stacks, if not removed by a scrubber. Why does SO 2 need to be scrubbed? Sulfur dioxide is a reactive gas so when it meets other gases within the earth's atmosphere, a fine, secondary particle forms.
