Among the many types of pollution-abatement systems in use today, wet fluegas desulfurization (FGD) systems – also known as wet scrubbers – are notoriously capital- and maintenance-intensive. Mist ...

In coal-fired power plants, measurement and control of pH is critical to the efficient operation of wet flue gas scrubbers. However, harsh process conditions can necessitate frequent cleaning and ...

Are you using your flue gas desulfurization (FGD) system to its highest potential? You might not be if you’re not making it do double duty. It seems that million ...

The flue gas desulfurization (FGD) process removes sulfur dioxide (SO 2) — one of the elements in acid rain — from fossil fuel power-plant emissions. FGD systems, commonly called scrubbers, encompass ...

In Part I of this two-part report ( COAL POWER, July/August 2007, p. 22), we introduced the integrated R&D effort by the U.S. Department of Energy’s National Energy Technology Laboratory (DOE/NETL) to ...
