Sulfur Recovery Units (SRU)

Advanced Environmental Compliance & By-Product Recovery

Turning Emissions into Assets

In today’s environmentally conscious energy sector, effective sulfur management is mandatory. Our Sulfur Recovery Units (SRU) are designed to remove toxic Hydrogen Sulfide (H2S) from acid gas streams and convert it into elemental sulfur, a valuable industrial by-product.

We provide complete EPC solutions for SRU plants, utilizing the industry-standard Claus process optimized for maximum conversion efficiency and reliability, ensuring compliance with strict SOx emission regulations.

99.9% Recovery Efficiency: By integrating Tail Gas Treatment Units (TGTU), our systems achieve near-zero emissions, meeting the most stringent global environmental standards.

Technical Capabilities

State-of-the-art process engineering for gas desulfurization.

Claus Process Units

The core of sulfur recovery. We design multi-stage catalytic reactors that convert H2S to liquid sulfur through thermal and catalytic reactions.

  • High-efficiency Reaction Furnaces
  • Waste Heat Boilers (WHB) for steam generation
  • Advanced burner management systems

Tail Gas Treatment (TGTU)

To maximize recovery, unreacted components from the Claus unit are processed in a TGTU, reducing SO2 emissions to negligible levels.

  • Reduction / Oxidation technologies
  • Amine absorption integration
  • Regulatory compliance guarantee
