Where:
CO2, CH4, or N2O, from Biomass = Biogenic CO2 emissions or emissions of CH4 or N2O from spent liquor solids combustion (metric tons per year).
Solids = Mass of spent liquor solids combusted (short tons per year) determined according to § 98.274(b) .
HHV = Annual high heat value of the spent liquor solids (mmBtu per kilogram) determined according to § 98.274(b) .
(EF) = Default emission factor for CO2, CH4, or N2O, from Table AA-1 of this subpart (kg CO2, CH4, or N2O per mmBtu).
0.90718 = Conversion factor from short tons to metric tons.
Where:
Biogenic CO2 = Annual CO2 mass emissions for spent liquor solids combustion (metric tons per year).
Solids = Mass of the spent liquor solids combusted (short tons per year) determined according to § 98.274(b) .
CC = Annual carbon content of the spent liquor solids, determined according to § 98.274(b) (percent by weight, expressed as a decimal fraction, e.g., 95% = 0.95).
44/12 = Ratio of molecular weights, CO2 to carbon.
0.90718 = Conversion from short tons to metric tons.
Where:
CO2 = CO2 mass emissions from makeup chemicals (kilograms/yr).
M (CaCO3) = Make-up quantity of CaCO3 used for the reporting year (metric tons per year).
M (NaCO3) = Make-up quantity of Na2CO3 used for the reporting year (metric tons per year).
44 = Molecular weight of CO2.
100 = Molecular weight of CaCO3.
105.99 = Molecular weight of Na2CO3.
