The Ministry of Mining and Energy has announced that construction of the desulfurization system at TENT B is nearly finished. All construction work is reported as complete, while testing of individual components is currently underway. The next phase involves commissioning activities tied to absorber units.
Absorber tests for flue gases and limestone suspension
The first successful release of flue gases and limestone suspension was carried out through absorber B1. Similar tests are planned for absorber B2 in mid-August. These absorber trials are part of the process verification for the desulfurization equipment.
Scale of investment in TENT A and TENT B plants
More than €400 million has been invested in desulfurization plants at TENT A and TENT B. The project is described as one of the largest environmental undertakings by the Electric Power Industry of Serbia (EPS). Last year, the system at TENT A was completed.
Both plants are expected to improve environmental protection and public health in Obrenovac and surrounding areas. EPS General Director Dušan Živković said the company will fully comply with European and domestic environmental standards once the systems are installed across its major thermal power plants. He cited Kostolac B and TENT A among the units covered by the approach.
Trial operation timelines and commissioning results
Milan Aleksić, advisor to the Minister, said the desulfurization systems are important for extending the operational life of Serbia’s key thermal power plants. He added that TENT B’s system is expected to enter trial operation by the end of the year. EPS officials also indicated that commissioning will proceed through staged testing.
A recent “hot test” involving absorber B1 confirmed that the technological process is functioning. White smoke from the chimney was reported as an indicator of proper operation during the test. Fine-tuning continues, with trial operation expected by mid-December.
Gypsum by-product from desulfurization process
The project also includes production of gypsum as a by-product. The material can be used in construction, according to EPS statements. This feature is presented as an additional outcome linked to the overall desulfurization effort.
