Using computational fluid dynamics (CFD) it is possible to simulate in the computer any type of leak and predict where gas concentrations above the detectable limit will be obtained and where the location of detectors will be really effective. The total number of combustible or toxic gas detectors is optimized considering different leak conditions and different wind conditions, may consider 100% of possible leakage points.
The use of this computational solution by CFD replaces the traditional tools of dispersion calculus, usually based on Gaussian models, that do not consider the iteration of the winds against obstacles and that can change the direction of dispersion of the gas clouds.
The CFD use shows excellent results in evaluation of pollutants dispersion or toxic gas dispersion of chimneys of industrial plants close to populated areas or environmental protection areas, facilitating the approval of projects by national and international environmental agencies.
Gas dispersion studies can be used for:
- Prepare the optimized design of gas detection system in any type of unit.
- To evaluate the quantity and explosive and toxic levels of large leakages.
- Check and establish the location and height of vent systems.
- Analysis of consequences of the dispersion of power generating boilers gas discharge, engines, etc., in places where the presence of people and/or its consequences on the landing and takeoff areas of aircraft.
- Check and establish location and height of chimneys of power generation plants or factories to attend the requirements of national or international environmental organ.
