1. Stack Sampling Results Report

2. It has the operating conditions of the source? NO
Cancelled report
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

3. 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

4. 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:

5. 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

6. Concentration Conversion
MM = molecular mass

7. 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

8. Convert SO3 and H2SO4 to SOx
Conc. SOX = Conc. SO2 + Conc. SO3 x 64/80
Conc. SOX = Conc. SO2 + Conc. H2SO4 x 64/98

9. N = normal condition
CNTP
1 atm e 0°C
1 atm e 273 K
1 atm e 492 R

10. Exercise: The source is attending the emission limits?
Source: Incinerador
Emission Limit to PM: 70 mg/Nm3, base seca a 7% de O2
Report:
1a sample = 50,238 mg/Nm3, base seca a 12,2 % de O2
2a sample = 43,951 mg/Nm3, base seca a 13,1 % de O2
3a sample = 43,185 mg/Nm3, base seca a 12,7 % de O2

11. Exercise: The source is attending the emission limits?
Source: Incinerador
Emission Limit to SOx: 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

12. Exercise: The source is attending the emission limits?
Source: Cement Kiln
Emission Limit to HF: 5 mg/Nm3, base seca a 7% de O2
Report:
1a sample = 8,5 mg/Nm3, dry base, 7 % O2
2a sample = ND
3a sample = ND
ND - not detectable
(quantitation limit = 8 mg/Nm3)

13. Exercise: The source is attending the emission limits?
Source: Cement Kiln
