Statistical Study of the Atmospheric Dispersion of Sulphur and Nitrogen Oxides at the Stack of a Special Waste Incineration Plant Located in the Southern Part of Timisoara

Abstract

This paper presents the zone maps resulted from the statistical processing of NOx and SOx emissions varying with the weather conditions. This study uses data from the nitrogen and sulphur oxides emissions monitoring collected in 2013-2016 from the on-line gas analyser with the incineration plant evacuation system, as well as hourly weather records for four parameters (atmospheric pressure, temperature, rainfalls, wind speed and direction) recorded at our own weather station in the same period. The statistical calculation and zone map drawing software was performed by our team members.

Study on Nanoparticles Flow Reduction Tests to Hwi Plants Using Numerical Simulations

“…The transport of settled particles experimentally defined below was numerically shaped through the original CloseView program (Strambeanu et al 2016). The time averaged DEP force acting on a spherical particle situated in an AC electric field can be written as (Morgan & Green 2003): where we denoted by a the particle radius,  the angular field frequency, and VR, respectively VI the real and imaginary part of the electric potential phasor, ̃= + , with = √−1.…”

The Influence of Meteorological and Topographical Parameters on the Dispersion of Pm10 and Co Pollutants

“…Meteorological factors, especially wind, significantly influence the levels of pollution and the spread of pollutants in the lower atmosphere (Chris, 2002). The transfer and dispersion of pollutants, which reach the atmosphere, take place according to the laws of turbulent diffusion, ie they are influenced by the direction and speed of the wind and the vertical gradient of temperature (Constantin et al, 2017, Strambeanu et al, 2016. The main objective of the study on the influence of meteorological factors on the dispersion of PM₁₀ and CO pollutants in Argeș County was to analyze how meteorological factors, especially direction and speed of wind, influence the phenomenon of air pollutant dispersion.…”

Air Pollution Meteorology. Case Study: So2 and No2 Monitoring in Argeș County

“…or to the penetration into the atmosphere of compounds foreign to this environment (radioactive elements, synthetic organic substances, etc.). Meteorological conditions determine how pollutants disperse through the air (Chris, 2002, Strâmbeanu et al, 2016. The time that pollutant emissions spend in the air and the place where the maximum pollutant concentration reaches the ground is influenced by several meteorological conditions, such as: thermal inversion, high air humidity, wind and calm atmospheric, etc.…”
