E = (cs Qsd) / (PK)
where:
E = emission rate of particulate matter, kg/Mg (lb/ton) of ammonium sulfate produced.
cs = concentration of particulate matter, g/dscm (g/dscf).
Qsd = volumetric flow rate of effluent gas, dscm/hr (dscf/hr).
P = production rate of ammonium sulfate, Mg/hr (ton/hr).
K = conversion factor, 1000 g/kg (453.6 g/lb).
P = ABCK 1/4
where:
A = sulfuric aid flow rate to the reactor/crystallizer averaged over the time-period taken to conduct the run, liter/min.
B = acid density (a function of acid strength and temperature), g/cc.
C = acid strength, decimal fraction.
K 1/4 = conversion factor, 0.0808 (Mg-min-cc)/(g-hr-liter) [0.0891 (ton-min-cc)/(g-hr-liter)].
P = DEFK'
where:
D = total combined feed stream flow rate to the ammonium crystallizer before the point where any recycle streams enter the stream averaged over the time-period taken to conduct the test run, liter/min.
E = density of the process stream solution, g/liter.
F= percent mass of ammonium sulfate in the process solution, decimal fraction.
K' = conversion factor, 6.0 * 10-5 (Mg-min) / (g-hr) [6.614 * 10-5 (ton-min) / (g-hr)].
