Transporting sulphur safely
Sulphur is a relatively safe and inert solid. However, it has a number of unique physical and chemical properties which can give rise to hazards, particularly during transport and handling.

Seshu Dharmavaram of Air Products and Venkat Pattabathula of SVP Chemical Plant Services describe the Dakar ammonia accident, which occurred in Senegal on March 24th, 1992. It is claimed to be the worst industrial ammonia accident ever, leaving 129 dead and 1,150 injured.
Yara International has approved a project to partly convert its Pilbara plant near Karratha in Western Australia to green ammonia production.
As we near the end of the third quarter of 2022, the attention of the nitrogen industry is focused on the coming northern hemisphere winter, and the prospects for higher natural gas prices as temperatures fall and power and heating demands rise. Vladimir Putin has been stoking these worries to try and force a climbdown from European countries over the sanctions that followed his invasion of Ukraine, with the flow of gas through the Nordstream 1 pipeline across the Baltic Sea gradually dwindling over the summer and finally stopping altogether at the end of August due to “technical issues” – an explanation somewhat undermined by the subsequent statement from spokesman Dmitry Peskov that gas would flow again once sanctions were eased. This is a familiar enough tactic; Russia has used gas stoppages to pressure Ukraine and Europe several times over the past two decades.
Canpotex is celebrating its 50th anniversary year in 2022. The world’s premier potash exporter has been exclusively marketing and distributing Canadian potash overseas since 1972. In this article, we profile this potash export colossus and look back at its landmark achievements over the past five decades.
The purpose of this article is to emphasise the lessons learned by ADNOC Sour Gas in the material upgrading of the Shah sulphur granulation plant due to severe corrosion of the aluminium components. The sulphur granulation plant was commissioned in 2015 and consists of a total of 12 granulating systems used for solidifying and granulating the liquid sulphur. The study focused on the corroded areas, namely the GX plenum chambers, the lower section of the granulator exhaust stack, the scrubber inlet and the discharge ducting.
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.
By using modular construction, operational modelling and digital plant control, thyssenkrupp Uhde can offer customers fast-build, capital efficient green ammonia plants. Dr Christian Renk and Dr Klaus Nölker explain the company’s innovative approach to plant construction, design and control.
Liquid fertilizers are emerging as a high growth, multibillion dollar market. Their growing use is linked to trends such as no-till farming and the greater adoption of precision agriculture. Leading producers and products are highlighted.
Economically viable production of green ammonia requires plants that can react to fluctuations in renewable power thanks to their flexible design. Casale’s Francesco Baratto, Giovanni Genova and Sergio Panza explain how new tools are helping design green ammonia plants that deliver the highest possible production at the lowest possible cost.
