The emission of NOX from production of catalysts/fertilisers decreases from
1996 to 2009, whereas the emission of NH3 increases. Fluctuations and the
increase in the “emission factor” can explain the increase in NH3 emission.
The emission of NMVOC from production of pesticides is reduced significantly
from 1990 to 2010 (Cheminova, 2010). The decrease can probably be
explained by introduction of flue gas cleaning equipment rather than any
decrease in activity. The emission of SO2 is from the sulphur regeneration
plant (Claus plant).
The time series will be explained further in the following section.

The emission of SO2, NOX, NH3 and TSP from production of sulphuric acid,
nitric acid and fertiliser is measured yearly or estimated, from 1990 to 2004
(TSP from 2000 to 2004) (Kemira GrowHow, 2005). PM10 and PM2.5 are estimated
from the distribution between TSP, PM10 and PM2.5 from CEPMEIP
(2003). The emission for SO2 and NOX for 1991 to 1993 was estimated by using
interpolated emission factors and activity data. Production of sulphuric
acid was stopped in 1997 and production of nitric acid was stopped in 2004.
The emission factor for SO2 fluctuated and the emission factor for NOX decreased
from 1990 to 2004. Production of sulphuric acid decreased from approximately
150 000 to 60 000 tonnes from 1990 to 1996, and production of
nitric acid decreased from approximately 450 000 to 229 000 tonnes from
1990 to 2004. Overall, production of fertiliser decreased from approximately
800 000 to approximately 395 000 tonnes from 1990 to 2004.
The emission of NH3, NOX and TSP from production of catalysts and fertilisers
is measured yearly from 1996 to 2010 (TSP from 2000 to 2010) (Haldor
Topsøe, 2011). PM10 and PM2.5 are estimated from the distribution between
TSP, PM10 and PM2.5 from CEPMEIP (2003). The process-related NOX emission
has been estimated as 80 % of the total NOX emission; Haldor Topsøe
reports this assumption in their environmental report. The emission of NH3
shows an increasing trend and varies between 13 and 123 tonne from 1990 to
2010. In the same period, the production of catalysts and fertilisers increased
from approximately 33 000 to 45 000 tonnes.
The emission of NMVOC from production of pesticides is measured yearly
from 1990 to 2000 (Cheminova, 2011) and estimated for 2001 to 2010. An
