Block 8: Environmental Issues and Public Health - Air Pollution Chapter 4: The Principal Sources Of The Common Air Pollutants; Methods Of Estimating Emission Rates (Continued)
 

CASE STUDIES:

A. Consol Glass:

Approximate data:

Fuel: HFO (heavy fuel oil);
Usage rate: 30 000 kl per annum;
sulphur content: 1.0 to 2.0 %S
stack heights: 45 to 60 m
Questions: What are:
  • the approximate SO2, PM10 and NOx emission rates?
  • Stack gas concentrations?
  • Ambient (ground level) concentrations?
B. Abnormal emissions example: Oil Refinery: flare at SAPREF (Durban)

Questions:
  • What is being emitted?
  • Emission rate?
  • Ambient concentrations?
  • Exposure-response relationships for the pollutants?
  • Health risks associated with the incident?
