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, | 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.

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, | Since 1990, fuel consumption has shown a slightly increasing trend overall.
