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 ...

The calcium carbonate (CaCO 3) in limestone is only slightly soluble in water, but in the presence of acid, it reacts much more vigorously. It is the acid generated by absorption of the SO 2 into the ...

A new analysis of data collected from various field tests allows more accurate estimations of sulfuric acid emissions from FCC units equipped with wet gas scrubbers. FCC units are potential sources of ...

The installation represents one of the first scrubber retrofits to be carried out in a Chinese yard, a reflection of the industry-wide acceleration in the global scrubber market. (Photo: CTG) (Left) ...
