Odour assessment and control

Odour assessment and control

In industrial terms, an odour is caused by one or more volatilized chemical compounds that are generally found in the atmosphere/ work place that workers/ recipients can perceive by their sense of smell. The odour assessment study pertains to the objectives including (i) identification of odour emission sources, (ii) establishing the possible reasons for odour events based on scientific studies, (iii) suggesting the effective and suitable odour control plans/measures.

  • Identification of odorous compounds and emission sources – speciation of odours compounds will be undertaken and all the process units will be reviewed to identify the point sources, fugitive sources, leaks, flare etc.
  • Emission inventory development – plant records and other scientific methods will be used for developing the emission inventory
  • Air Quality Modelling – to identify the impact zone due to the emissions identified, USEPA approved air quality modelling tools will be used.
  • Simulation of Odour events – the actual odour events recorded will be simulated based on the actual emissions data and real time metrological data to identify the possible root cause of the odour event.
  • Health risk assessment – USEPA approved health risk indicators will be used to undertake the health risk assessment. The odour nuisance and potential chronic effects including cancer risk will be evaluated based on the predicted odour concentrations.
