Flue Gas Desulphurization Plant at TENT A

The First Quantities of Gypsum Produced

The flue gas desulphurisation plant (FGD) and the thermal power plant "Nikola Tesla A" produced the first quantities of gypsum as a by-product of the desulphurisation process. Euro-quality gypsum was obtained after a month of functional hot tests using absorbers C2 for units A5 and A6. The construction of the FGD plant at TENT A is currently the most important environmental project undertaken by "Elektroprivreda Srbije" and is valued at almost EUR 205 million.
According to Ljiljana Velimirović words, Project Manager for the Construction Project of the FGD plant in TENT A, in the produced gypsum the percentage of moisture is less than 10 per cent, gypsum more than 95 per cent, magnesium oxide is less than 0.1 per cent, sodium oxide less than 0.06 per cent, chloride less than 0.01 per cent. The annual production of gypsum is expected to be about 600,000 tons.
- In the upcoming period, functional hot tests will continue with absorber C1 for units A3 and A4. The process and other pipelines are currently undergoing their final assembly and testing. However, the booster fan of unit A3 still needs to be tested, which will require several days of downtime. Once the testing is complete, the absorber will be ready for hot tests, and the release of the first flue gases from unit A4 is expected at the end of January. This will mark the finalisation of the implementation, which finalises the implementation - Velimirović says.
The entire FGD plant is scheduled to be handed over for use at full capacity on March 28th.
- By purifying flue gases to four 350-megawatt units of TENT A, significant environmental benefits will be achieved. Following European standards and domestic regulations, the concentration of sulphur oxides will be reduced below 200 milligrams per cubic meter, while the concentration of powdery substances will be below 20 milligrams per cubic meter. At the FGD plant in TENT B, which is under construction, this concentration of sulphur oxides will be below 130 milligrams per cubic meter - said Srđan Josipović, Director for Power Generation of the TENT Branch.
