Descaling Solutions for Flue Gas Desulfurization (FGD) - Goodway
Maintenance of Flue Gas Desulfurization (FGD) processes is an important part of power plant operations. Without desulfurization, flue gases can be filled with unacceptable levels of sulfur dioxide (SO2) emissions, that are in violation of EPA regulations. A common way to reduce these emissions is to employ wet scrubber operations, using hydrated lime (lime slurries). However, …
