E = (cs Qsd)/(PK)
where:
E = emission rate of particulate matter, kg/Mg (lb/ton).
cs = concentration of particulate matter, g/dscm (gr/dscf).
Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
P = asphalt roofing production rate or asphalt charging rate, Mg/hr (ton/hr).
K = conversion factor, 1000 g/kg [7000 (gr/lb)].
P = (Vd)/(K' [THETA])
where:
P = asphalt charging rate to blowing still, Mg/hr (ton/hr).
V = volume of asphalt charged, m3 (ft3).
d = density of asphalt, kg/m3 (lb/ft3).
K' = conversion factor, 1000 kg/Mg (2000 lb/ton).
[THETA] = duration of test run, hr.
Where:
d = Density of the asphalt, kg/m3 (lb/ft3)
K1 = 1056.1 kg/m3 (metric units)
= 64.70 lb/ft3 (English Units)
K2 = 0.6176 kg/(m3°C) (metric units)
= 0.0694 lb/(ft3°F) (English Units)
Ti = temperature at the start of the blow, °C ( deg;F)
