Formula
SO2 = Fuel x Sulfur% x 2 x (1 - Control/100)
SO2 mass equals fuel times sulfur fraction times 2 (MW ratio) reduced by scrubber efficiency.
Worked Examples
Example 1: Coal Plant FGD
Problem:5000 kg/hr, 2% S, 6000 hr, 90% FGD.
Solution:S = 100 kg/hr SO2 = 200 kg/hr Total = 1200000 kg Ctrl = 120000 kg
Result:120000 kg/yr
Example 2: Oil No Scrubber
Problem:2000 kg/hr, 1% S, 4000 hr, 0%.
Solution:S = 20 kg/hr SO2 = 40 kg/hr Total = 160000 kg
Result:160000 kg/yr
Frequently Asked Questions
How is SO2 emission calculated from sulfur content?
SO2 is calculated by multiplying fuel consumption by sulfur fraction and then by 2.0 which is the molecular weight ratio of SO2 to sulfur. Each kilogram of sulfur produces 2 kilograms of SO2 when fully oxidized during combustion. The formula assumes complete conversion which is valid for over 95 percent of sulfur in most systems.
