Abstract：To meetthedemandoffluegasdesulfurizationincoppersmelting，theapplicationofionicliquiddesulfurization process in acid-making fluegas and ring-collected flue gas was studied.Problems such as large fluctuation of SO 2 concentrationand insuffcientregeneration eficiencyduring operationwereanalyzed.Byoptimizing thepre-absorption system，increasing steamsourcesandheatrecovery，thestableoperationoftwodesulfurizationsystems asrealized.The results indicatethatthesystem'semissonindicatorsare stableand meetthespecial emission limitrequirementsofnational standard，providing a reference for similar enterprises.
