B&W's proven technology, flexibility of design options and advanced features of our wet flue gas desulfurization (FGD) systems help to reduce emissions in new or retrofit applications.. Our wet FGD systems, or wet scrubbers, have operated efficiently, economically and reliably since 1971. Current designs can achieve more than 99% SO 2 removal, with system availability greater than 99.5%.

Mar 09, 2004· Scrubbed flue gas passes through a mist eliminator and is emitted to the atmosphere from a stack or cooling tower. Figure 1. A typical wet FGD (flue gas desulfurization) system Figure 1 illustrates the limestone desulphurization process which consists of the following process steps:
