FGD Pumps Ideal for Power Stations in South Africa

2009-10-12 · Otten explains that more than 90% of global installations use lime or limestone as the absorbent to neutralise flue gases. “This translates into slurry concentrations which vary between 15 to 30 % by weight, obviously depending on the type of process, and this means that pumps operate in highly corrosive and erosive conditions,” he says.

Flue gas desulfurization effluents: An unexploited

2018-7-1 · Wet limestone FGD system. The wet limestone FGD process (non-regenerable) is based on complex acid-base reactions that take place under forced or natural oxidation conditions. According to the reactions of the desulfurization process, two regions can be differentiated in most of the scrubbers: the gas-to-liquid contact zone and the reaction tank.
