· Flue gas desulfurization (FGD) is a technology used to remove sulfur dioxide (SO 2) from the exhaust flue gases of fossil fuel power plants. Fossil fuel power plants burn coal or oil to produce steam for steam turbines, which in turn drive electricity generators. Sulfur dioxide is one of the elements forming acid rain.

One of the most recent power stations in the Iberian Peninsula, Sines is also among the three most efficient coalfired plants in that area. In 2017, due to a highefficiency rate of %, the Sines power plant boasted a CO2 emission factor of TonCO2/MWhe (an,3 ktonCO2 emission against 9426 GWh of electricity generated) probably among the lowest in the Iberian Peninsula.
WhatsApp · 1. Introduction. The term Flue Gas Desulphurisation (FGD) system has traditionally referred to wet scrubbers that remove SO 2 emissions from large electric utility boilers. The FGD systems emerged in the industrial field of the coalfired power plants and on some industrial processes in the early 1970s in United States (US) and Japan, and expanded rapidly in the 1980s in Europe.

Coalfired power plants and coalfired industrial boilers constitute a large and important source of atmospheric mercury emissions. In 2010, coal burning was responsible for the emission of some 475 tons of mercury worldwide, the majority of which was from power generation and industrial boiler use (UNEP, 2013a). This represents about 40 per cent of the total global anthropogenic emissions
