Boost capacity of SRUs with mixing devices for oxygen enrichment
The requirement for additional sulfur recovery unit capacity in a refinery may stem from hydroprocessing operations; a refinery expansion project; a shift from lighter to heavier, sourer crudes to improve margins; or the need to remove extra sulfur content to meet tighter environmental regulations.
