Low-cost FGD systems for emerging markets

摘要

Emerging markets have been calling for several years for new, lower-cost flue-gas desulfurization technologies as an alternative to the mature, proven FGD systems that are currently available. In response to this demand, ABB has developed new FGDtechnologies that perform as well or better than conventional systems at a much reduced cost. Three main technologies are used to control sulfur dioxide emissions: limestone-based wet, lime-based dry or seawater FGD. The optimum FGD solution for aparticular installation depends on many site-specific factors, which can be technically and/or financially driven.
