In recent years, there found are many places in which the concentration of nitrogen dioxide (NO_2) exceeds the environmental quality standard where automotive exhaust gas the likely to collect, such as road intersections at urban areas, underground parking lots, bus terminals, etc. The Acid Gas Eliminator removes nitrogen dioxide at an efficiency as high as 80%, and simultaneously it is also able to remove smoke and soot. To examine the effect of compact gas purification system, numerical simulations of airflow and pollutant diffusion in a two dimensional cross section were carried out. The calculated results show that the gas purifier works to improve the road side environment under low wind condition.
