Question

In 1986 an electrical power plant in Taylorsville, (Georgia, burned 8, 376, 726 tons of coal, a national record at that time. Assuming that the coal was 82.3 % carbon by mass and that combustion was complete, calculate the number of tons of carbon oxide produced by the plant during the year. Express your answer numerically in tons. Assuming that the coal was 3.90 % sulfur by mass and that combustion was complete, calculate the number of tons of sulfur dioxide produced by the plant during the year. Express your answer numerically in tons.

Explanation / Answer

Q1.

a)

mass of coal = 8376726 ton of coal

assume 82.3% is C

calculate mass of CO2 produced:

so

12 kg of C --> 44 kg of CO2

12 ton of C --> 44 ton of CO2

mass of C --> (82.3/100)*(8376726 ) = 6894045.498 ton of C

so.. ton of CO2 = 44/12*6894045.498 = 25278166.826 ton of CO2

B)

if 3.9 is sulfur...

32 ton of S --> 64.066 ton of SO2

so..

3.9/100*8376726 = 326692.314 ton of S in coal...

ratio is 64/32 so..

Ton of SO2 = 326692.314*2 = 653384.628 ton of SO2 produced
