TABLE 2-2: Price Differentials for Low-Sulfur Fuels
|Low-Sulfur Fuel Type||Price difference ($ US/GJ-%S)n||Typical Heating Value (GJ/tonne)||Cost (US $) per tonne SO2 removed|
|Hard coal and coke, 0.6% S||0.34||27||482o|
|Heavy fuel oil, 0.6% S||0.54||41.5||1111|
|Diesel-redn. To 0.3% S||0.84||42.5||1784|
|Diesel-redn. To 0.05% S||2.52||42.5||5352|
n. Dollars per gigajoule of fuel energy and per percent of sulfur reduced compared to the original fuel. One gigajoule (GJ) is one billion (109) joules. For purposes of comparison, 34 kg of (standard) coal or 31 liters of gasoline have an energy content of about one gigajoule.
o. Calculated (by the original source) assuming that 5 percent of fuel sulfur remains in the ash after combustion. From Technological Alternatives to Reduce Acid Gas and Related Emissions from Energy-Sector Activities in Northeast Asia by David Von Hippel
