Cancelledreport It has the operating conditions of the source? NO yes The sampling equipment has calibration certificate? NO yes NO Laboratory analysis reports comply the legal requirements? yes Analyze the report
Stack Sampling Results Report • the results in concentration shall be expressed in the same oxygen content of the emission limit • To correct the oxygen is necessary to apply this expression: Where: y is the oxygen in the flue gas • x is the oxigen of the emission limit
Stack Sampling Results Report Example: To correct a concentration obtained in a sampling (135 mg/Nm3 to 9% O2) for the content of 7% oxygen will be:
Stack Sampling Results Report • the results in concentration shall be expressed in the same unit to the emission limit • Example: the average readings of continuous monitor of CO was 100 ppm, but emission limit is mg/Nm3
ConcentrationConversion MM = molecular mass
Stack Sampling Results Report • the results in concentration shall be expressed in the same unit to the emission limit • Example: the average readings of continuous monitor of CO was 100 ppm, but emission limit is mg/Nm3 124,944 mg/Nm3
ConvertSO3 and H2SO4 to SOx Conc. SOX = Conc. SO2 + Conc. SO3 x 64/80 Conc. SOX = Conc. SO2 + Conc. H2SO4 x 64/98

Exercise: The source is attending the emission limits? • Source: Incinerador • EmissionLimitto PM: 70 mg/Nm3, base seca a 7% de O2 • Report: 1asample = 50,238 mg/Nm3, base seca a 12,2 % de O2 2asample = 43,951 mg/Nm3, base seca a 13,1 % de O2 3asample = 43,185 mg/Nm3, base seca a 12,7 % de O2
Exercise: The source is attending the emission limits? • Source: Incinerador • EmissionLimittoSOx: 250 mg/Nm3, base seca a 7% de O2 • Report: Concentração de SO2 = 54,2 mg/Nm3, dry base, 12,2 % O2 Concentração de H2SO4= 11,4 mg/Nm3 , dry base, 12,2 % O2
Exercise: The source is attending the emission limits? • Source: CementKiln • EmissionLimitto HF: 5 mg/Nm3, base seca a 7% de O2 Report: 1asample = 8,5 mg/Nm3, dry base, 7 % O2 2asample = ND 3asample = ND ND - notdetectable (quantitationlimit = 8 mg/Nm3)
Exercise: The source is attending the emission limits? • Source: CementKiln • EmissionLimittoNOx: 650 mg/Nm3 • Report: the average readings of continuous monitor of NOx was 1000 ppm
