If unknown divide the MMBtu/hr rating by a 1,000 to convert to MMscf. Then multiply by 8760 hours/yr to get the yearly value. Emissions are based on 55% methane and 98% destruction efficiency. If your values vary significantly from these defaults use the detailed spreadsheet. Emissions are calculated by the summmation of the multiplications of the corresponding landfill gas rate and the Emission Factors.SubstanceCAS#**Landfill Gas Emission Factor Total Derived Default lbs/ MMscfTotal LB/HRTotal LB/YR1,1-Dichloroethane~753431.19E-021.19E-031.19E+001,2-Dichloropropane~788751.04E-031.04E-041.04E-01Acetaldehyde750702.37E-032.37E-042.37E-01Acrolein1070281.49E-031.49E-041.49E-01Acrylonitrile~1071311.71E-021.71E-031.71E+00Benzene714324.40E-034.40E-044.40E-01Bromodichloromethane~752742.62E-022.62E-032.62E+00Carbon disulfide~751502.25E-032.25E-042.25E-01Carbon Tetrachloride~562353.14E-053.14E-063.14E-03Carbonyl sulfide~4635811.50E-031.50E-041.50E-01Chlorobenzene~1089071.44E-031.44E-041.44E-01Chlorodifluoromethane (Freon 22)~754565.74E-035.74E-045.74E-01Chloroform~676631.83E-041.83E-051.83E-02Dichlorofluoromethane {Freon 21}~754341.38E-021.38E-031.38E+00Ethyl Benzene1004143.02E-023.02E-033.02E+00Ethyl chloride (Chloroethane)~750034.12E-034.12E-044.12E-01Ethylene dibromide (EDB)~1069349.59E-069.59E-079.59E-04Ethylene Dichloride~1070622.07E-032.07E-042.07E-01Fluoranthene2064409.35E-039.35E-049.35E-01Formaldehyde500009.35E-039.35E-049.35E-01Hexane1105433.24E-023.24E-033.24E+00Hydrogen Sulfide~77830646.17E-026.17E-036.17E+00Isopropyl Alcohol~676301.54E-011.54E-021.54E+01Mercury~74399762.99E-062.99E-072.99E-04Methyl Chloride (Chloromethane)~748733.12E-033.12E-043.12E-01Methylene chloride (Dichloromethane)~750926.20E-026.20E-036.20E+00Methyl Chloroform~715563.27E-033.27E-043.27E-01Methyl ethyl ketone~789332.61E-022.61E-032.61E+00Methyl isobutyl ketone (Hexone)~1081019.56E-039.56E-049.56E-01Naphthalene912031.65E-041.65E-051.65E-02PAH's11512.20E-042.20E-052.20E-02p-Dichlorobenzene~1064671.58E-031.58E-041.58E-01Perchloroethylene~1271843.16E-023.16E-033.16E+00Propylene1150714.02E-014.02E-024.02E+01Toluene1088832.01E-022.01E-032.01E+00Trichloroethylene~790161.89E-021.89E-031.89E+00Vinyl chloride~750142.34E-022.34E-032.34E+00Vinylidene Chloride~753549.89E-049.89E-059.89E-02Xylenes13302078.05E-028.05E-038.05E+00References:* The emission factors were derived from using default values for methane combustion and Biomethane characterization.
