-Refinery processes are very complex. Therefore the development of an adequate calculation method is demanding. Since plant specific data are not complete and partly contradictory, a plant specific reporting is not possible. Data is used to determine fuel specific emission factors as general basis of the calculation model. However, in reality, a large number of several fuels and waste fuels with different fuel characteristics is used for combustion processes. Insofar the calculation model is limited. +Refinery processes are very complex. Therefore the development of an adequate calculation method is demanding.

 Only some refinery power plants use wet desulfurisation in order to decrease sulfur emissions. Usually the fuels mix ensures the compliance with the limit values.       Only some refinery power plants use wet desulfurisation in order to decrease sulfur emissions.

-Fuel inputs for electricity production in refinery power stations are included in Energy Balance line 12 ("Industrial thermal power stations").

 Emission factors are available for different fuel types and combustion technologies. The distinction between refinery power plants and bottom heating in refinery processes is necessary since bottom heating systems have considerably higher specific emissions. Emission factors are available for different fuel types and combustion technologies.

 Before the new emission factors can be used, it has to be checked which data are representative. Further quality checks are necessary in order to reproduce the trend correctly.  Before the new emission factors can be used, it has to be checked which data are representative.

 Since 1990, fuel consumption has shown a slightly increasing trend overall. While some relevant installations have been decommissioned since 1990 - especially in the territory of the former GDR - production increased nevertheless. And while installation efficiencies were improved, increased production of lighter petroleum products and intensified hydrosulphurisation, which led to increases in specific fuel consumptions. Annual fluctuations of all fuel types can be explained as the result of differences in production quantities. The maximum production of petroleum products to date, totalling 123.6 million t, occurred in 2005, as a result of a shortfall in capacity in the USA, which led to an increase in imports. Thereafter, production decreased by reducing excess capacities like everywhere in Europe. Since 1990, fuel consumption has shown a slightly increasing trend overall.

 ===== Recalculations ===== ===== Recalculations =====
  
-Recalculations were necessary for the latest reference year (2017) due to the availability of the National Energy Balance. Germany has a federal structure which causes a time lack of the National Energy Balance. Therefore, recalculations are always necessary. +For the purpose of improving the data quality National Energy Balances for the years 2003 to 2021 have gone under revisions through fine-tuning of the computational models, consideration of new statistics or re-allocation of activity data, along with other revision mechanisms. These updates led to re-calculations in fuel uses in different sub-categories and in their corresponding emissions.
