Audit Sample Calculation Tool Equations

 

Sample Volume (dscm):
Vm(std) (dscm) = Qm ?
Vm(std) = Sample Volume (dscm)
Qm = Sampling Rate (dscm/hr); (Default: 1 liter/min or 0.06 m3/hr � Mtd 6 Section 8.3.1)
? = Total Sampling Time (hr)
Est In-Stack Gas Concentration (lb/dscf):
CSO2 (lb/dscf) = ESO2 (lb/hr)/Qstd (dscf/hr)
CSO2 = Estimated In-Stack Gas Concentration for SO2
ESO2 = SO2 Emission Limit (lb/hr)
Qstd = Stack Flow Rate (dscf/hr)
Est In-Stack Gas Concentration (mg/dscm):
CSO2 (mg/dscm) = (CSO2 (lb/dscf)) (35.315 dscf/dscm) (453,592 mg/lb)
Est In-Stack Gas Concentration (ug/dscm):
CSO2 (ug/dscm) = (CSO2 (mg/dscm)) (1000 ug/mg)
Audit Concentration (mg/mL):
Ca (mg/mL) = [(CSO2 (mg/dscm)) (Vm(std) (dscm))]/Vsoln (mL)
Ca = Audit Concentration
Vsoln = Final Diluted Volume per Method (mL); (Mth 6 para 11.2.1 = 100 ml)
Audit Concentration (mg/L):
Ca (mg/L) = (Ca (mg/mL)) (1000 mL/L)
Audit Mass (ug):
Ma (ug) = (CSO2 (ug/dscm)) (Vm(std) (dscm))
Ma = Audit Mass
Audit Mass (mg):
Ma (mg) = (Ma (ug))/(1000 ug/mg)
Audit Mass (ng):
Ma (ng) = (Ma (ug)) (1000 ng/ug)
