Transporting sulphur as a dry bulk solid can lead to it breaking into small particles which create dust. Over the years, various forming processes have been developed to try and minimise dust formation and produce the strongest, most resilient formed sulphur particles.
Join us at the CRU Sulphur + Sulphuric Acid 2024 Conference and Exhibition in Barcelona, 4-6 November, for a global gathering of the sulphur and sulphuric acid community. Meet leading market and technology experts and producers, network, share knowledge, and learn about market trends and the latest developments in operations, process technology and equipment.
IPCO has expanded its Rotoform range with the high yield XG model for granulation of suspensions. Designed for applications such as sulphur bentonite and urea mixes as well as NPK and other fertilizers, this new Rotoform model can convert solid-containing product melts into consistent, high quality pastilles from 2-4 mm diameter.
Specialty fertilizer products represent a small volume, high value segment of the overall fertilizer market that’s been growing at around four percent per annum in recent years. Economic, environmental, regulatory and agronomic imperatives are driving up their adoption – and an overall shift from volume to value in the fertilizer market.
Mark Brouwer and Jo Eijkenboom of ureaknowhow.com examine the major shifts in global urea production. They also discuss the future of the urea industry and, in particular, how the sector is being affected by the increasing focus on low-carbon ammonia production.
A report on CRU’s annual Sulphur + Sulphuric Acid conference, held in New Orleans, USA, 6-8 November 2023.
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.
Sulphur is a vital secondary crop nutrient. It can be delivered in sulphate, thiosulphate and elemental form. The range of product and process options are outlined.
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.
It is generally necessary to solidify sulphur into a robust form suitable for handling and long-distance transport. Granulation, pastillation and prilling are some of the technologies used to produce solid sulphur from molten material. Similar technologies are also used to manufacture sulphur fertilizers.
