Sulfur Recovery

In refining and gas processing, sulfur isn’t just a byproduct—it’s a challenge and an opportunity. From liquid sulfur degassing to tail gas treating, sulfur recovery units must operate with precision, safety, and sustainability. Evonik sulfur-recovery catalysts support Claus and tail-gas-treating performance, emission-control targets and catalyst-life requirements under defined operating conditions.

Why Choose Evonik for Sulfur Recovery?

• Proven Performance: Trusted brands like MAXCEL® 727, 777, TG and EcoMax TG® ensure reliable operation across demanding sulfur recovery units.
• Sustainability at the Core: Evonik sulfur-recovery catalysts support SO₂ emission-control targets, catalyst-life management and catalyst-reuse approaches for defined SRU and tail-gas-treating operations.
• Tailored Innovation: From traditional to sub-dew point Claus processes, including tail gas units, to release agents, our portfolio adapts to your specific recovery and treatment needs.
