Claus plants in refineries process concentrated hydrogen sulfide (H2S) fractions converting them into elemental sulfur. They can also remove pollutants, particularly by decomposing ammonia.
Stricter environmental regulation leads to products with lower sulfur content. As a result Claus plant loadings with hydrogen sulfide and ammonia are increasing and the Claus plant may become a bottleneck.
The problem can be overcome by oxygen enrichment of the combustion air. This increases the capacity significantly. A new type of burner ensures excellent mixing of hydrogen sulfide and oxygen enriched air over a wide load range.
Benefits of oxygen enrichment:
Increased Claus plant capacity
Increased productivity without changing the pressure drop
More effective treatment of ammonia containing feeds
Less effort for tail gas purification (reduced nitrogen flow).
