IPM Model Updates to Cost and Performance for APC

Units below 100 MW will typically not install a wet FGD system. Sulfur reductions for the small units would be accomplished by treating smaller units at a single site with one wet FGD system, switching to a lower sulfur coal, repowering or conversion to natural gas firing, dry sorbent injection, andor a reduction in operating hours.

Flue gas desulfurization systems are classified as either non-regenerable or regenerable. Non-regenerable FGD systems, the most common type, result in a waste product that requires proper disposal. Regenerable FGD converts the waste by-product into a marketable product, such as sulfur or sulfuric acid.
