Fluegas scrubbing Fluegas scrubbing is a process for removing oxides of sulfur and nitrogen from the waste gases emitted by various industrial processes. Since the oxides of sulfur and nitrogen have been implicated in a number of health and environmental problems, controlling them is an important issue. The basic principle of scrubbing is that flue gases are forced through a system of ...

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.

Abstract. ASPEN Plus simulations have been created for a CO 2 capture process based on adsorption by monoethanolamine (MEA). Three separate simulations were developed, one each for the flue gas scrubbing, recovery, and purification sections of the process. Although intended to work together, each simulation can be used and executed independently.

SO 2 is formed during the combustion of coal. The amount of SO 2 produced depends on the sulfur content of the coal burned in a boiler. FGD scrubbers remove the SO 2 from a boiler's postcombustion exhaust (flue gas) by passing it through an alkaline solution. This process is also effective in removing acid gases, such as hydrochloric acid.
