PLTU Tanjung Jati B is a steam power plant with a supply capacity of 4×660 MW located at the edge of Semenanjung Muria Pulau Jawa. With one of the largest production capacities in Indonesia, PLTU Tanjung Jati B can supply around 12% of Indonesia’s total electricity demand to the Java-Bali electrical grid. Electricity is produced by utilizing steam generated by the burning of sub-butiminous coal in any of the 4 boiler rooms. As a result of this burning, PLTU Tanjung Jati B generates gaseous emissions in large quantities as a by-product. A major gaseous emission that is generated is sulfur dioxide. In 2017, PLTU Tanjung Jati B generated sulfur dioxide emissions as much as 6,641,187.15 kg SOx/year for Unit 1 and 8,518,913.98 kg SOx/year for Unit 2. This amount has the potential to drastically increase due to a potential change in the quality of coal used as fuel in the near future. To ensure that the amount of gaseous emissions released into the atmosphere by PLTU Tanjung Jati B does not exceed the limits set by PermenLH No. 21 Tahun 2008 and cause environmental contamination, a re-design of the existing air pollution control system is needed. The existing system will be re-designed into a flue gas desulfurization system implementing a lime scrubbing process with the use of a packed column inside the absorber. The new absorber unit will have an efficiency of 87.69% with a diameter of 26 m and a total height of 27.3 m. The system will produce marketable gypsum as a by-product which will be treated by a thickener and gypsum centrifuge unit.
