Bosnia & Herzegovina: A three-month test run of hot flue gas desulphurisation at RiTE’s Ugljevik coal-fired power station in the Republika Srpska region began on 13 December 2019. The Euro80m installation will reduce sulphur dioxide (SO₂) emissions to 200ppm from 16,000ppm, in accordance with European Union standards, and produce an unspecified quantity of gypsum. Ugljevik manager Čedomir Stojanović said, “we are considering the construction of a second plant.”

India: GE Power India has won three wet flue gas desulphurisation (FGD) projects. A contract worth US$335m covers the supply and installation of FGD systems at two NTPC coal power plants, the Simhadri Super Thermal Power Station and the Sipat Super Thermal Power Station, and one Aravali Power Company plant, IGSTPP Jhajjar.

GE’s scope includes design, engineering, civil work, supply, erection and commissioning of Wet FGD systems along with auxiliaries, including limestone and gypsum handling systems and wet stack on full turnkey basis. In addition, GE’s scope for IGSTPP Jhajjar also includes 10 years of operation and maintenance including the supply of spare parts.

With these three wet FGD projects together, GE will help NTPC to treat 35Mm³/hr of flue gas and will remove up to 0.11Mt/yr of SO₂, which will be converted into gypsum by-product for use in the construction industry.
