ABSTRACT:
A process is disclosed to produce a commercially valuable concentrated nitrogen sulfur solution by scrubbing sulfur dioxide from flue and other gases using ammonium sulfite solution as a scrubbing media. The process also has the capability of removing the sulfur dioxide as an insoluble zinc or calcium salt from the scrubbing solution without having to regenerate, recover and recirculate gaseous ammonia.
