The most important air pollutants relevant to our type of industry are:
- Nitrogen oxide (NOx)
- Fine dust (Particulate matter between 2.5 and 10 micrometers)
- Volatile Organic Compounds (VOCs)
- Greenhouse gases (CO2, methane, and CFCs)
NOx, CO2, and many fine dust emissions originate from combustion processes – for example, within the naphtha crackers.
Because hydrocarbons are the first base material for all SABIC-installations, nearly all plants contribute to VOC emissions.
Benzene and methane originate mostly from naphtha crackers and logistic activities.
In recent years, SABIC maintained its downward trend in air emissions. For example, the emission of volatile organic compounds (VOCs) decreased as a result of improved furnace performance and better fugitive emission monitoring of our naphtha crackers.
Generally speaking, emissions from point sources (chimneys, smokestacks, etc.) are tightly monitored and controlled. As point source emissions reduce, possible fugitive emissions (from gaskets, valves, etc.) come into greater focus for monitoring and prevention.
