* Removal efficiency values reported below are calculated by comparing inlet concentrations versus outlet concentrations considering the acid gas scrubber only and do not include the acid gas reductions initially affected by virtue of dry line injection into the furnace. Thus, the removal efficiency values reported below are understated (e.g. total actual acid gas removal efficiencies are higher than reported here).
