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.
