HONEYWELL UOP SULFUR RECOVERY Reducing Emissions with High Reliability MEET ENVIRONMENTAL REGULATIONS WITH EASE From a global leader in refining and gas processing technology, UOP’s sulfur recovery systems meet the industry’s most stringent environmental regulations with high reliability and operational flexibility, leading to increased profitability. Sulfur is removed as a contaminant RELIABLE RECOVERY STAY ON-STREAM from crude oil and sour gas streams to SOLUTIONS Conventional sulfur recovery units reduce harmful emissions and protect With half a century of Ortloff™ sulfur are often plagued with reliability and downstream equipment. It can also be recovery engineering, design and startup operability issues that cause costly recovered as a marketable by product. experience and more than 100 installations unplanned shutdowns. Based on As sulfur dioxide emissions regulations worldwide, UOP has developed a continued innovation and hands-on become more stringent globally, refiners comprehensive portfolio of sulfur recovery owner/operator experience, UOP has and gas processors need proven sulfur units (SRUs) with high recovery efficiencies developed unique sulfur recovery unit recovery solutions to reliably comply and excellent on-stream times. UOP designs that are more robust, easier with the strictest requirements. technology stems from the professional to operate and less prone to corrosion adaptation of the best industry processes and failure. This results in service combined with proprietary technology and lives of more than 30 years and KEY ADVANTAGES expertise. UOP experts work with refiners significantly minimizes both planned and gas processors to select the most and unplanned shutdowns. • Excellent plant reliability with cost-effective sulfur recovery solution to on-stream times of 99-plus percent reliably meet their processing goals. • Cost-effective, streamlined modular solutions available COMMON SRU UOP SRU DESIGN BENEFIT PROBLEM SOLUTION • 30-plus year service lives for Allows for startup without warming robust waste heat boiler designs Catalyst deactivation and Cold catalyst bed catalyst reactor beds, reducing refractory damage during startup capability the risk of fire or sooting, extend- • Minimal operator and maintenance startup design ing catalyst life and preventing attention required refractory failures Eliminates the most frequent • Longer time between turnarounds Lost revenue from boiler Robust waste heat cause of extended SRU shutdowns with fewer catalyst change-outs failures boiler design and sulfur shedding with industry- leading performance Dependable valve designs Unreliable switching Superior sulfur eliminate solids formation, valve valves vapor valve design sticking and leakage which can cause high emissions Avoids extended shutdowns from Tailgas Cleanup Unit Improved TGCU water accumulation in the blower (TGCU) startup blower blower location casing and reduces emissions failure during startup and shutdown Generates saturated or superheated Wasting the heat value Tailgas Thermal high pressure steam with less of the fuel gas consumed Oxidizer (TTO) waste fuel gas consumption than an in incineration heat recovery auxiliary boiler Saving between $2 million to $20 million per turnaround for a 400 kbpd refinery UOP SRU SOLUTIONS tailgas cleanup processes to achieve UOP Selectox™ Processes recovery efficiencies up to 99.95 UOP Ortloff Modified Claus Process The Selectox and Recycle Selectox™ percent.
