- Flue gases containing primarily substantial amounts of sulphur compounds that are particularly harmful to environment and live beings are an uncomfortable waste product of lignite firing. Desulphurisation is a good method to reduce the content of such compounds in flue gases.
- The process of a wet flue gas desulphurisation system involves the direction of flue gases from electrostatic filters to an absorber where they are exposed to lime wash.
- An array of chemical reactions results in binding of contaminants (particularly SO2) into synthetic gypsum.
- After leaving the absorber zone, flue gases, which are already free of sulphur, pass through two levels of a mist eliminator where sorbent suspension droplets are caught for removal from flue gases. Finally, having passed through a pre-heating chamber, the treated flue gases are discharged through a stack integrated with the system. The entire process is largely automated.
- The desulphurisation system treats flue gases in approx. 96% and environmentally friendly, uncontaminated water vapour flows out of the chimneystack.

Such a highly effective approach, commonly used in the world’s power industry, has been accepted by the Konin power plant where ZE „PAK” SA has implemented one of the biggest pro-ecological investment projects of the recent years.
