There is a growing skills gap in the sulphur industry due to the changing nature of the workforce. The traditional ways of doing things are no longer working effectively. Knowledge is lost with retiring subject matter experts (SMEs) and other experienced operations staff leaving a reducing pool of SMEs. In this article a case study reviews how knowledge automation solved the skills gap in a sulphur recovery unit at a major US refinery.
Debopam Chaudhuri of Fluor Daniel India Pvt Ltd and Michiel Baerends of Fluor B.V. Netherlands investigate how SO2 impacts the Claus furnace temperature in an SRU and the ways to mitigate it. This article studies the extent of quenching experienced in the Claus furnace with varying amounts of SO2 in the Claus feed. A case study is presented based on real operating data of a refinery Claus plant with a feed gas cocktail that includes substantial SO2 recovered from a regenerative flue gas desulphurisation unit.
Sulphur dust is one of the greatest hazards when producing and handling solid sulphur, and methods for its suppression are vitally important to prevent fire and explosion.
Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.
The centre of gravity of the phosphate industry continues to shift, with Chinese exports less important, and fresh demand coming from India and Brazil.
Kazakhstan’s oil and condensate output increased by 7% from 1.79 million bbl/d to 1.92 million bbl/d in early June after sour gas reinjection operations resumed at the Kashagan offshore oil and gas development following a recent outage, according to the Kazkah Energy Ministry. Reinjection of sour gas into two wells resumed on 8th June, enabling operator the North Caspian Operating Company (NCOC) to boost oil and condensate production at a large artificial island in Kazakhstan’s Caspian Sea waters. Reinjection was paused on May 20th following the detection of sour gas during routine sampling and a subsequent integrity test. Kashagan normally produces about 300,000 barrels of oil per day. Kazakhstan expects Kashsgan to raise oil production this year to 18.2 million t/a from 12.7 million t/a in 2022.
The 2023 Middle East Sulphur Conference (MEScon 2023) was the biggest sulphur event in the region to date with over 650 attendees representing 23 countries from across the sour gas and sulphur value chain. More than a conference, this annual event offers conversation, collaboration and community, with leaders and experts from across the industry sharing knowledge, best practice and predictions for the future of sulphur.
Indonesian imports have increased in 2023 so far on a year earlier. As new nickel high pressure acid leach projects ramp up, demand for sulphur is expected to increase further. Swing buyers have been importing significant volumes of sulphuric acid, affecting short term sulphur demand in the second quarter. It remains to be seen if this will continue, we expect sulphur demand to ramp up further in the second half of the year, bringing import expectations for the year to around 2 million t.
Aged sulphur products can be friable and fragile, which can lead to sulphur dust during handling. Because sulphur dust can lead to dust explosions and excessive wet sulphur contact corrosion, shipping and handling specifications for the safest products are used by producers, shippers and consumers to limit dangerous incidents. Metastable polymeric sulphur in the solid product limits friability and is rarely cited as a measured quantity within sulphur specifications, but often discussed when explaining best handling and forming practices. In this article, ASRL discusses why sulphur tends to be friable and explores several measurements cited in many specification documents, with the purpose of focusing on several modern solid forms. In addition, the measurement of total and extraneous water is explored.
Market Insight courtesy of Argus Media. Urea: Scarcity continued to drive urea prices higher in some markets at the end of April. The US market remains short on urea and prices spiked to reflect this. Nola barges for April were trading as high as $450/st f.o.b. ($490/t cfr), 55 percent up on this year’s low point. Southeast Asia remains short on urea too, amid planned and unplanned turnarounds, with one cargo trading at around $345/t f.o.b.
