Overview of Air Dispersion Modelling

Ecoprime Services Limited can be relied upon for comprehensive and state-of-the-art air dispersion modelling.

We have the ability to run a broad range of dispersion models and can recommend the modelling approach that would best suit your needs. Ecoprime Services has extensive experience and expertise in utilizing relevant dispersion models to demonstrate regulatory compliance against current and proposed air quality standards, criteria and guidelines. Ecoprime Services has completed odour modelling for numerous projects, including frequency of exceedence at sensitive receptors analysis and the preparation of graphs illustrating predicted odour concentrations, as required by many ECAs.

What is Air Dispersion Modelling?

Air dispersion modelling is the use of mathematical formulations to simulate atmospheric processes and predict the dispersion of pollutants. It is a tool used as part of an air quality risk assessment, usually to support either Environmental Permit or Planning Applications. Any facility or development that emits pollutants to air could need a dispersion modelling assessment for example:

Industrial sites, chemical plants;
Food and drink factories;
Boilers and Combined Heat and Power plants (CHP) on any of the above sites;
Medium Combustion Plants and Specified Generators;
Power stations, Waste to Energy, Carbon Capture plants;
Data centers – emergency back-up generators; and
Animal rearing / intensive agriculture / farms e.g. for odour emissions, ammonia emissions.

Benefits of Dispersion Modelling

Whilst dispersion modelling is more time and cost expensive than basic assessments, it can also result in capital expenditure savings especially where it is employed early in the design process and feeds into cost-benefit-analysis, for example: a dispersion model can:

Identify potential constraints early in the design stage and assist in findings solutions;
More accurately define appropriate stack heights than basic methods (like D1 calculations), and usually shows lower stack heights are sufficient; and
More accurately define abatement requirements e.g. a combination of increased stack height and less expensive lower maintenance abatement system may achieve the same results as multi-stage abatement (identify cross-environmental benefits).
