What is Air Pollution?

Air pollution occurs when gases, dust particles, fumes or odors are introduced into the atmosphere, which has harmful or poisonous effects. The common air pollutants are :

  • SCR Selective Catalytic Reduction,Zeolite Catalyst

    01

    Nitrogen dioxide
    (NO2)

  • SCR Selective Catalytic Reduction,Zeolite Catalyst

    02

    Particulate matter
    (PM10 and PM2.5)

  • SCR Selective Catalytic Reduction,Zeolite Catalyst

    03

    Ozone
    (O3)

  • SCR Selective Catalytic Reduction,Zeolite Catalyst

    Carbon monoxide
    (CO)

  • SCR Selective Catalytic Reduction,Zeolite Catalyst

    05

    Sulphur Dioxide
    (SO2)

  • SCR Selective Catalytic Reduction,Zeolite Catalyst

    06

    Volatile Organic Compounds
    (VOCs)

Nitrogen Oxides and its Harmful Effects

Nitrogen oxide is a collective term used to refer nitrogen monoxide (NO) and nitrogen dioxide(NO2), which is produced from the reaction of nitrogen and oxygen gases in the air during combustion, especially at high temperatures. And NOx emitted into the atmosphere is harmful to the human body such as coughing, phlegm, respiratory disorders, and reacts with ultraviolet rays and dust to cause photochemical smog and ultrafine dust.

SCR Selective Catalytic Reduction System

SCR Process is a technology in which NOX and NH3 are reduced to molecular nitrogen (N2) and molecular water vapor (H2O) by chemical reaction on the catalyst surface. This is a post-processing technology of the combustion process that can reduce nitrogen oxides (NOX) from combustion gases of fossil fuels such as coal, oil, and natural gas to less than 10%. It has the highest and most stable removal efficiency among denitrification technologies.

Flue Gas Desulfurization (FGD) Systems

FGD process is the dominant worldwide method for the control of SO2 emissions. It is a technology that reduces the concentration of Sulfur Oxides in the flue gas system through a chemical reaction process with a reagent, such as lime.

Activated Carbon

Activated carbon is a type of carbon that has been processed to increase the surface area and porosity. This makes it an effective adsorbent that can attract and hold other molecules on the surface. Activated carbon is used for various purposes such as water purification, air purification, odor control, and so on.
