A newly formed partnership between AMETEK Process Instruments and Worley Comprimo, part of Worley’s Technology Solutions, has provided sulfur recovery unit (SRU) stakeholders with critical analytical measurements combined with advanced burner control technology to deliver enhanced automated air control management.
The implementation of the 2ACT™ Solution ensures plant operators gain a fully automated system that minimises SRU upsets, enhances reliability, and delivers strong returns on investment. At the heart of this partnership, the 2ACT Solution offers an all-in-one approach to advanced air control – significantly boosting SRU performance and efficiency while reducing operational costs. The 2ACT Solution uses AMETEK’s IPS-4 ultra-violet and infrared analyser to measure H2S, CO2, NH3, H2O and total hydrocarbons (THCs) by continuously sampling the acid gas upstream of the SRU. The change in air demand requirement is then calculated, with main and trim air adjustments implemented automatically by the feed forward control scheme designed by Worley Comprimo.
In SRUs, tail gas/air demand analysers provide accurate concentration analysis of sulfur compounds, providing important insight into sulfur recovery efficiency and a means of feed-back adjustments of the trim levels of air or oxygen at the thermal reactor. Plant engineers have been investigating ‘feed-forward’ analysis, which is the addition of H2S, CO2, NH3, H2O and THC measurements of the acid gas feed to the SRU, to further optimise efficiency, reduce downtime and comply with emissions regulations. This feed-forward analysis combined with advanced burner control technology enables the reduction in reaction time to changes in feedstocks that may cause SRU plant upsets or an unwanted increase in emissions.
Benefits of the 2ACT Solution include maintaining an optimal H2S to SO2 ratio at the outlet of the Claus Plant to maximise recovery efficiency, mitigating damage to tail gas treatment unit (TGTU) components, lowering SO2 emissions and carbon footprint with improved uptime and plant throughput.
Mike Hevey, Division Vice President and Global Business Manager at AMETEK, said: “While we have the measurement device and experience, it was important to work with a leading partner to provide a completely automated solution for plant operators. Worley Comprimo covers all aspects of the sulfur value chain, making them the ideal fit, enabling our two companies to deliver this solution that ultimately reduces downtime, costs and emissions”.
Frank Scheel, Senior Vice President at Worley Comprimo, stated: “Combining the right analyser with the smart designed feed forward control provides our joined customers with a valuable tool to operate their Sulphur plant and control their emissions accurately.
“The 2ACT Solution, developed by industry-leading experts, provides SRU stakeholders with the critical measurements and air control system design, to finally close the loop on feed-forward enabled, advanced burner controls.”
