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.

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.

Meena Chauhan , Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.

The production of renewable fuels by retrofitting existing refineries and their infrastructure is witnessing exponential growth. The impact on the existing amine, sour water and sulphur recovery units is inevitable. Based on several case studies, Marco van Son, Shashank Gujale and Tammy Chan of Worley Comprimo discuss the various options available to holistically review the sulphur block to determine the impact and mitigation of processing bio-feed.

Sulphur production continues to expand in the Middle East and China both from new refineries and major sour gas projects.

The Sulphur Institute (TSI) held its World Sulphur Symposium in Edinburgh from April 25th to 27th.

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.

As part of the expansion of the Shah gas plant (SGP) in the United Arab Emirates, a new 12-inch pipeline was designed and commissioned in January 2020. Hassa Al Mulla, Ravi Srinivas and Alsail Al Jaberi of ADNOC Sour Gas highlight the best practices implemented in the newly commissioned liquid sulphur pipeline.

A reader wrote to me recently asking if I had considered the impact of general artificially intelligent systems like ChatGPT on the publishing industry. As a matter of fact I had, but only, somewhat narrowly and selfishly, on how it might impact my own job in the future. But the dramatic shift in AI capabilities that we have seen in the past couple of years is certainly food for thought, and I’ve seen no end of articles predicting the death of the creative industries.
