The best example is the reduction of mercury emissions achieved through the application of desulfurization measures.

The best example is the reduction of Hg emissions by the desulfurization installations.

For oil, emphasis has been placed on the development of technology for improving the desulfurization rate and producing low sulphur.

The application of flue gas desulfurization (FGD) has a very important impact on removal of not only sulfur dioxide but also mercury.

With regard to coal, emphasis has been placed on the development of cleaner technologies, improvement in electricity generation efficiency, desulfurization and denitrofication, underground gasification and vaporization by combustion.
