Kreber’s R&D department has been researching the prilling of sulphur in pursuit of the ideal process. In this article, T. Nieboer of Kreber recounts the history of prilling up to today, tracing the developments and highlighting the challenges that still remain.
Sulphur demand in Australia has been boosted by the restart of the nickel leaching plant at Ravensthorpe, and new HPAL projects are under development, but a slew of new phosphate projects are not scheduled to consume more acid domestically.
With increasing frequency, companies that have molten sulphur on site must put environmental controls on the vent streams from molten sulphur pits, storage tanks and loading operations. This article* describes the typical characteristics of molten sulphur vent gas streams as well as some of the important chemistry related to these systems in caustic scrubbers. Solids deposition issues observed in the field with caustic scrubbers operating on actual molten sulphur vent gas streams are presented. Design and operational strategies to mitigate plugging in molten sulphur vent gas scrubbers are also summarised in this article by D. J. Sachde, K. E. McIntush, D. L. Mamrosh , and C. M. Beitler of Trimeric Corporation.
Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.
Ordinarily I try to choose a different subject each issue for an editorial, but as April lengthens towards May, and here in the northern hemisphere we start to see the first signs of summer, there unfortunately remains only one subject that is obsessing every industry, and that is the Covid-19 pandemic and its impact upon every aspect of our lives. Since our last issue we have all had to come to terms with ‘lockdown’ and ‘social distancing’, as the grim toll of deaths climbs in all regions. Here at BCInsight we are working without an office as best we can, and issues of Sulphur will continue to land in your email inboxes, but paper copies of the magazines may take longer to arrive, if at all, as shipping and customs procedures are tightened all around the world, and I can only apologise and ask that you bear with us.
How the macro market responds to the coronavirus pandemic over the months ahead and governmental response in different parts of the globe will likely have a lasting impact on the outlook for the sulphur market.
A look at the major factors influencing the sulphur market around the world.
West Texas Intermediate (WTI) forward oil prices for May dropped into negative territory during mid-April, on fears of lack of storage capacity to deal with the excess production. Forward prices for June were also nosing to equally unprecedentedly low levels.Elsewhere, Brent Crude spot prices dropped to $20/bbl, a fall of $50/bbl from the start of 2020.
Sulphur’s annual survey of recent, current and future sulphur recovery unit construction projects maps the developing shape of brimstone production from fuel and gas processing plants worldwide.
The Indonesian government’s decision to enforce the processing of more copper and nickel ores domestically rather than export them to China has led to the rapid development of domestic smelter capacity as well as nickel acid leaching projects.
