+ | ===Activity Data=== | ||
+ | |||
+ | There are two kinds of processes called chloride process and sulfate process for the production of titanium dioxide. The total production amount is attained from the German Federal Statistical Office[(ProStat> | ||
+ | |||
+ | For the calculation of individual production of each process, the fraction of chloride process is determined based on the estimated total production capacity in Germany (480 kt/y) and the production capacity via chloride process (165 kt/y) [(https:// | ||
+ | |||
+ | ===Emission Factors=== | ||
+ | |||
+ | Emission factors for Titanium dioxide production are the Tier 2 emission factors from EMEP Guidebook: NO< | ||
+ | |||
+ | The applied Tier 2 emission factors are listed in Table 1 [(European Environment Agency: EMEP/EEA air pollutant emission inventory guidebook 2019, Part B: sectoral guidance chapters, 2.B Chemical industry (Oct 2019): pp.25-26, table 3.19 and table 3.20)]. | ||

+ | The association of the titanium producers reports the sum of SO< | ||
+ | |||
+ | Except for SO< | ||
+ | |||
+ | As the emission factors are constant over the time the emission trend is influenced only by the development of the production. | ||
+ | |||
+ | |||
+ | ===== Recalculations ===== | ||
+ | For SO₂ emissions from the production of **titanium dioxide** and **sulphuric acid**, estimates reported for the //second to last year// of the time series are routinely actualised by the producers. Furthermore, | ||
+ | |||
+ | As the SO₂ emissions from titanium dioxide are no longer confidential, | ||

+ | ===== Planned improvements ===== | ||
+ | |||
+ | For 1990 and 1991 for reasons of confidentiality the SOx-emissions were replaced by the emissions value from 1992. Meanwhile the confidentiality does not anymore exist. So for the next submission the real SOx for 1990 and 1991 will be published. |
