Answer 2

Answer:

The two major emissions control methods are sorbent injection and flue gas desulfurization: Sorbent injection involves adding an alkali com- pound to the coal combustion gases for reac- tion with the sulfur dioxide. Typical calcium sorbents include lime and variants of lime. Sodium-based compounds are also used.
