However, environmental regulations continue to tighten, putting growing pressure on Claus sulphur recovery processes and this step can become a bottleneck within the refinery.
Boosting efficiency
You can overcome this problem by enriching the combustion air in a Claus plant with oxygen. This increases the capacity significantly. Our innovative burner technology ensures excellent mixing of hydrogen sulphide and oxygen-enriched air over a wide load range.
Benefits of oxygen enrichment
• Increased Claus plant capacity at low revamp capital cost
• Increased productivity without changing the pressure drop
• More effective treatment of feeds containing ammonia
• Greater flexibility in handling feed gas composition variations
• Less effort for tail-gas purification (reduced nitrogen flow)
• Ease of installation with minimum disruption to plant operation.
We have the technology and expertise to enable all levels of oxygen enrichment – from low levels through mid levels up to 100% oxygen with our SURE burner technology. Our SURE solution is a tip mixed design offering low pressure drop, operational flexibility and enhanced contaminant destruction.
