For a general process description of a gas scrubber, please refer to ‘gas scrubbing – general’. In an alkaline scrubber, acid-forming components are collected via neutralisation using a base as scrubbing liquid. This leads to the formation of salts, which can eventually be reprocessed.

WebNov 1, 1982 · Introduction In Dec. 1977, SFEC contracted with FMC Corp. to install a double-alkali sulfur dioxide absorber serving a group of eight generators consisting of five 62.5-MMBtu/hr (18.44-MW) new steam generators, one 25-MMBtu/hr (7.33-MW) new steam generator, and two 25-MMBtu/hr (7.33-MW) existing steam generators. WebDual alkali scrubbers have been used for gas streams with up to 15% SO 2, but these are exceptions and generally not recommended. Dual alkali scrubbers provide the performance of sodium scrubber with the reagent consumption costs of a lime scrubber. However, a dual alkali system requires more equipment than either lime or sodium WebU.S. Environmental Protection Agency US EPA swallowing too much while high
