Abstract: ABSTRACT The present invention discloses a system for prevention of SO2 slippage in a Quench column of a Tail gas treating unit within a sulfur recovery unit (SRU). A method for prevention of SO2 slippage in a Quench column of a sulfur recovery unit (SRU) is also disclosed. The system comprises an SO2 analyzer to measure gas concentration, automatic valves to divert gas to a wash column if SO2 concentration exceeds set limit, and a controller to regulate valve operations. The wash column uses a circulating caustic solution to reduce SO2 concentration to desired concentration. The method comprises measuring SO2 concentration, diverting gas to the wash column, washing with caustic solution, and routing spent solution for treatment.
