so2 emissions Safe and efficient

A steady increase of the design SO2 removal efficiency can be noted for wet limestone and spray drying processes. This improvement may be due, in part, to the increasing need to better control SC2 emissions. However, the trends do reflect that the SO2 removal efficiency for the processes considered has improved with time.
