The Claus Oxygen Enrichment of sulfur recovery units (SRU) is a popular, economic, reliable, and safe method for addressing the dual needs of providing additional sulfur removal capacity while conserving capital for more profitable operations. Implementation of oxygen enrichment is the most economic route for incremental SRU capacities. For grassroots facilities, oxygen enrichment can effectively reduce equipment sizes and thus provide significant savings on capital investments and operation costs.
Fluor offers three distinct SRU oxygen enrichment technologies designed for the level of capacity increase desired. These technologies, ranging from low-level to medium-level to our patented high-level COPE® process, provide capacity increases from 10% to 100% or more.
