Abstract： This paper introduces the application of complexing tower desulfurization process to treat the problems such as foul smell and solution turbidity in the filter press room and oxidation tower of the exhaust from Chunfeng Crude Oil Refinery. Through analysis， the method of adding an oil absorption tower and a hydrolysis protection tower in front of the complexing iron device is adopted to solve the problem. The purified gas enters the complexing iron desulfurization device after the oil removal rate is more than 95% and the organic sulfur conversion rate is more than 90%， thus realizing a satisfying effect.
