Step 3: Calculate the annual mass of coal required.
The annual heat input required (Qin) is 5.230251×1010 MJ/year.
The calorific value of coal is 29.7 MJ/kg.
Mcoal=CalorificValueQin
Mcoal=29.7MJ/kg5.230251×1010MJ/year
Mcoal=1.7609936×109 kg/year
Mcoal≈1.76×109 kg/year
To convert to metric tons (1ton=1000 kg):
Mcoal=1.76×106 tons/year
Step 4: Determine the amount of particulates produced.
Particulates are primarily composed of ash. The ash content in the coal is 7.7%.
Mparticulates=Mcoal×Ash content
Mparticulates=1.7609936×109kg/year×0.077
Mparticulates=1.3569651×108 kg/year
Mparticulates≈1.36×108 kg/year
To convert to metric tons:
Mparticulates=1.36×105 tons/year
The amount of particulates produced annually is 1.36×108kg/year.
Step 5: Determine the amount of CO2 produced.
The carbon content in the coal is 77.0%.
The combustion reaction for carbon is C+O2→CO2.
Molar mass of C ≈12.01 g/mol.
Molar mass of CO2≈44.01 g/mol.
The mass of carbon in the coal is:
MC=Mcoal×Carbon content
MC=1.7609936×109kg/year×0.770
MC=1.3569651×109 kg/year
The mass of CO2 produced is:
MCO2=MC×MolarmassofCMolarmassofCO2
MCO2=1.3569651×109kg/year×12.0144.01
MCO2=4.97400×109 kg/year
MCO2≈4.97×109 kg/year
To convert to metric tons:
MCO2=4.97×106 tons/year
The amount of CO2 produced annually is 4.97×109kg/year.
Step 6: Determine the amount of SO2 produced.
The sulfur content in the coal is 1.0%.
The combustion reaction for sulfur is S+O2→SO2.
Molar mass of S ≈32.07 g/mol.
Molar mass of SO2≈64.07 g/mol.
The mass of sulfur in the coal is:
MS=Mcoal×Sulfur content
MS=1.7609936×109kg/year×0.010
MS=1.7609936×107 kg/year
The mass of SO2 produced is:
MSO2=MS×MolarmassofSMolarmassofSO2
MSO2=1.7609936×107kg/year×32.0764.07
MSO2=3.5182×107 kg/year
MSO2≈3.52×107 kg/year
To convert to metric tons:
MSO2=3.52×104 tons/year
The amount of SO2 produced annually is 3.52×107kg/year.
