2.B.10.a - Other Chemicals

Short description

In sub-category 2.B.10.a - Other Chemicals, emissions from the production of organic chemicals, titanium dioxide, sulphuric acid, carbon black, fertilizers and from the chlor-alkali industry are reported. Relevant pollutants are NMVOC, CO, PCDD/F, SOx, NH3, PM2.5, PM10, TSP and Hg.

Methodology

Organic products: activity data and emission factors

The annual production volumes for all organic products are extracted from national production statistics 1)) by the Federal Statistical Office.

Organic products comprise:

  • Acrylonitrile
  • Ethylene
  • Ethylbenzene
  • Ethylene Dichloride
  • Ethylene Oxide
  • Formaldehyde (Methanal)
  • Methanol
  • Phthalic Anhydride
  • Propene
  • Styrene
  • Vinyl Chloride
  • Polyethylene (LD/HD)
  • Polypropylene
  • Polystyrene
  • Polyvinyl Chloride
  • Styrene Copolymeres

The emission factors for the production of organic products as shown in table 2 and 3 are derived from best reference documents polymers and LVOC mostly for the early years. For later years, plant-specific data on an aggregated level were used.
