Scientists are testing the effect of different scrubber technologies on the removal of pollutants from coal power plants. The sc
Andre45 [30]

Answer:

When a water and limestone slurry is used as a scrubber, the impact of modifying the slurry by increasing the amount of limestone has as a consequence that the amount of sulfur dioxide released will decrease.

Explanation:

One of the consequences of the use of coal as fuel is the emission of toxic gases, one of which is sulfur dioxide (SO₂), a colorless and toxic gas that can affect the health of humans and animals. That is why SO₂ scrubbers are necessary for the removal of this gas.

One of the most commonly used SO₂ scrubbers is the suspension of water and limestone, since the calcium (Ca) contained in the limestone reacts with the SO₂ to form calcium sulfide (CaS), which precipitates as a solid, decreasing the emission of SO₂ to the environment.

It is for this reason that, by <u>increasing the amount of limestone in the scrubber slurry, more SO₂ will react, and the amount released from this gas will decrease.</u>
