Where:
E = Mass of halogen atoms, dry basis, kilograms per hour.
K2 = Constant, 2.494 * 10-6 (parts per million)-1 (kilogram-mole per standard cubic meter) (minute/hour), where standard temperature is 20 °C.
Vs = Flow rate of gas stream, dry standard cubic meters per minute, determined according to Method 2, 2A, 2C, or 2D of appendix A of 40 CFR part 60, as appropriate, or determined using engineering assessment as specified in paragraph (b) of this section.
n = Number of halogenated compounds j in the gas stream.
j = Halogenated compound j in the gas stream.
m = Number of different halogens i in each compound j of the gas stream.
i = Halogen atom i in compound j of the gas stream.
Cj = Concentration of halogenated compound j in the gas stream, dry basis, parts per million by volume.
Lji = Number of atoms of halogen i in compound j of the gas stream.
Mji = Molecular weight of halogen atom i in compound j of the gas stream, kilogram per kilogram-mole.
