In a few short years Abu Dhabi has grown to become the world’s largest sulphur producer and exporter, and new sour gas projects will lead to additional sulphur recovery capacity, provided they can overcome economic challenges.
It’ s not a very worthy thought, I’m afraid, but I must admit it was my first reaction on seeing the terrible pictures from Beirut on August 4th. The explosion that ripped through the centre of the historic and much troubled Mediterranean city was captured from many different smartphone cameras, and watching the expanding vapour cloud from the supersonic shockwave, and witnessing the sheer size of the explosion, it seemed immediately evident to me that it had to be a high explosive responsible, not the fireworks that could be glimpsed sparkling beforehand in the smoke from the burning warehouse. The rising cloud of orange-brown nitrogen dioxide that followed the blast was the clincher – it looked like it was ammonium nitrate yet again.
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.
Although amine solution foaming problems have been studied and reported extensively, direct correlations about the root causes of foaming have not been completely established. This article approaches the problems of foaming from a different perspective, rather than theoretical discussions, the topic is centred exclusively on Amine Experts’ field-related experiences with amine foaming episodes.
IPCO provides an update on its latest activities, with flexible processes enabling IPCO’s project for the first drum granulation plant in Europe to remain on track despite unprecedented Covid-19 restrictions.
At the end of last year, in our November/ December 2019 issue, I remarked upon the fresh impetus that the International Maritime Organisation’s (IMO) target of reducing carbon emissions from shipping by 50% in 2050 (compared to a 2008 baseline) had given to the idea of using ammonia as a shipping fuel. This year, in spite of You Know What, things seem to have, if anything, accelerated.
Haldor Topsoe and Sasol have announced that they have entered into a collaboration agreement to jointly license their GTL technologies. For many years, the two companies have worked together on numerous GTL projects and technologies, and Topsoe’s Syn-COR™ syngas generation technology and Sasol’s Fischer-Tropsch technologies have been licensed for several world-scale GTL ventures. Under the new collaboration agreement, the companies will continue to offer these core technologies, but will now also provide Topsoe’s hydroprocessing and hydrogen technologies. This gives potential customers access to a single-point licensing offering that covers the entire value chain from gas feed to liquid fuels. As single-point licensors, Sasol and Topsoe will offer customers all necessary technology licenses for a complete GTL solution and in addition provide basic engineering, catalysts, and hardware.
Sirius Minerals is in talks with Anglo American about a £386 million cash offer for its UK-based polyhalite mine project.
