With the challenges facing the global refining industry, refiners should review their current practices to see how they can stay competitive and continue to thrive in today’s market. This means improving operational efficiencies and producing products at a lower cost, whilst ensuring performance and safety. Brian Visioli of Evonik explores the development of catalyst reuse and how recycled hydroprocessing catalysts can be successfully applied in tail gas treating units to deliver cost and performance gains.

Bedeschi has been awarded a contract by Tecnicas Reunidas and Wison Engineering for the engineering and supply of new sulphur-handling equipment. Tecnicas Reunidas and Wison Engineering are working in a 70-30 joint venture partnership on the North Field Expansion Project (NFXP) Sulphur Project, which forms part of the overall Qatar North Field Expansion Project. Last year were awarded a $600 million contract to process and export sulphur from the projected expansion of the liquefied natural gas (LNG) facilities in Ras Laffan Industrial City. The new sulphur plant will have the capacity to process an average of 5,000 t/d of molten sulphur.

Inshan S Mohammed of Sulfur Recovery Engineering shares the lessons learned from an emergency shutdown of an MCRC sulphur recovery unit in the middle of a cold Canadian winter where temperatures can be -30°C.

Gerald Bohme and Joe Brindle of Sulphur Experts Inc. combine new learnings, historical data, and recent onsite experience from operating companies to show what factors really impact ammonia plugging risk and what can be done to control them in order to allow for a wider operating range for SWS processing in the refinery SRU.

Following the success of VectorWalls™ in the reaction furnace of sulphur recovery units over many years, VectorWalls™ are now delivering similar benefits in SRU thermal incinerators. Uday N. Parekh of Blasch Precision Ceramics reports on the deployment of VectorWalls™ to improve the performance of the SRU thermal incinerator and provide benefits such as lower fuel gas consumption and lower CO2 emissions.

SO2 breakthroughs remain an ever present threat to the successful operation of reductive, quenchamine-based tail gas clean-up units (TGUs). Effects can range from mild and annoying to quite severe, including failure to comply with environmental permit regulations and refinery shutdown. G . Simon A. Weiland, Nathan A. Hatcher, Prashanth Chandran, Daryl Jensen, Ralph H. Weiland, Jeff Weinfeld of Optimized Gas Treating, Inc. and Michael Huffmaster , Consultant.

In the current energy transition era, the oil and gas industry is focusing on lowering its carbon footprint while generating green energy resources such as blue hydrogen. In this article, Thomas K. Chow, Marcus Weber and Denny Li of Fluor Solutions/Goar, Allison & Associates, L.L.C. demonstrate how SRU/TGTU plants within sour gas facilities can facilitate the capture of CO 2 and generate H 2 by implementing advanced sulphur recovery technologies.

Lithium miner Ioneer Ltd has signed a non-binding Memorandum of Understanding with Shell Canada Energy for the supply of sulphur to Ioneer for its Rhyolite Ridge lithium-boron project in Esmeralda County, Nevada. Ionner said in a statement that “securing the supply of key reagents for ore processing is an important step along the critical pathway to developing the Rhyolite Ridge project”. Under the memorandum, Ioneer will purchase up to 500,000 t/a of high-quality sulphur from Shell, which would fulfil the estimated annual sulphur requirement for the Project.

A move towards so-called ‘sustainable aviation fuels’ (SAF) could see refineries having to recast their operations. What might this mean for sulphur production?

Enhancing the reliability of sulphur plant starts in the thermal stage. Matt Coady and Martin McCallister of Delta Controls report on a recently developed and launched insertable process camera that monitors the vessel interior of online Claus thermal reactors, providing valuable process data which will allow plants to make better informed operation decisions.
