Question 3.
An energy production plant has exhaust consisting of mainly two
types of gases, i.e., NO and SO2, requiring treatment
before the discharge. The plant decides to adopt the selective
catalytic reduction and flue gas desulfurization methods by using
Ammonia and limestone to remove the aforementioned gases. Please
write down the correct chemical reaction and estimate the amount of
Ammonia and limestone required per day for the treatment. Assuming
the plant produces 1.5 t and 2 t of NO and SO2 per hour
respectively, the plant operates 24/7, and the treatment efficiency
is 100%. The Atomic weight: N (14 g/mol), H (1 g/mol), O (16
g/mol), Ca (40 g/mol), S (32 g/mol), C (12 g/mol).
