Claus Sulfur Recovery Unit
The high-concentration H2S gas obtained after natural gas desulfurization is mixed in controlled proportions with air or oxygen and combusted ina furnace.
Application
Througha series of catalytic reactions, the hydrogen sulfide is converted into elemental sulfur, achieving both resource recovery and effective reduction of environmental impact.
In a typical surface processing train the sequence is: Wellhead → Separation → Treating → Metering → Pipeline.
Scope of supply
Capacity, design conditions and scope of supply are confirmed per project.
