Meet emission challenges with reliable Claus tail gas unit performance

Meet emission directives while improving your sulfur management. In today’s oil and gas industry, maximizing sulfur recovery from off-gases is extremely important. Regulations get tighter, forcing operators to constantly optimize the efficiency of their sulfur management units. Adding a tail gas treating plant to your Claus unit will enable you to meet the most stringent emission targets for final sulfur removal from the off-gases.

The effluent from a Claus plant is the feed for the Claus tail gas treating unit, which mainly consists of nitrogen and water; however, it also consists of SX, SO2, COS, CS2, CO, H2S, and H2 which need further treatment. The sulfur containing compounds and CO are hydrotreated and hydrolyzed to H2S and CO2 in the Claus tail gas treating unit, and H2S is recycled for conversion in the Claus unit.

We offer a range of tail gas treatment catalysts that allow you to reach overall sulfur recoveries of 99.9% and minimized pressure drops, which ultimately prolong the cycle length of your unit. With our solutions, you can balance optimal performance and process economics while ensuring low investment.

Key benefits:
• Low reactor inlet temperature
• Low catalyst pressure drops
• Low catalyst bulk densities
