Abstract: The continuous upgrading of environmental specifications promotes the technical progress of tail gas sulfur recovery. Based on the analysis of the technical difficulties of sulfur recovery for meeting the specifications of the tail gas, the advantages and disadvantages and adaptability of several typical technologies, such as LS-DeGas, alkali washing of flue gas, desulphurization of ammonia, Cansolv SO2 washing using organic amine, as well as super-optimal Claus+ alkali washing of flue gas, were introduced an compared. In view of the current situation of enterprises and environmental constraints, suggestions on technology selection were proposed on the basis of overall consideration of investment, operation cost and emission indexes.

Key words: sulfur recovery, tail gas treatment, Claus reaction
