Decreasing the carbon intensity of sulphur recovery is one of the many actions that operators can take to help meet their climate ambitions. It is also becoming increasingly rewarding financially because of the rising cost of carbon emissions. In this article, G. Kidambi of Shell Projects & Technology demonstrates the potential to cut the carbon intensity of tail gas treating units by more than 50% through swapping to the latest SCOT ULTRA amine solvent and catalyst technologies.

The processed phosphates market will be a major indicator for price direction for sulphur markets in 2022. A significant downward correction is expected in DAP prices with early signals prices could soften in the February-March period.

As the world looks to a lower carbon future, refineries are having to examine their operating models, and look to, for example, renewable hydrogen production for desulphurisation technologies.

N. A. Hatcher, D. R. Jensen , and P. L. Ott of Optimized Gas Treating Inc. provide a technology overview of ProBot™ – a unit monitoring system developed by OGT to digitalise the sulphur processing assets in a facility in a manner that facilitates knowledge retention, rapid optimisation, and plant troubleshooting. ProBot™ has been built to allow rapid access to a virtual plant platform that provides advice, training and, monitoring to enable more efficient, safe, reliable, and environmentally friendly plant operations.

Import duties on phosphates from Morocco and Russia imposed by the US government in 2021 have compounded a lack of availability of phosphate fertilizer caused by Chinese export restrictions and led to higher prices for US farmers. Are there knock-on effects possible for sulphuric acid demand?

A look at papers presented at CRU’s annual Sulphur + Sulphuric Acid conference, which was once again held virtually, in November 2021.

It’s a slightly dispiriting fact about the sulphur industry that most of its producers don’t really want it. If you’re a refiner or a sour gas producer, you mainly care about the diesel and gasoline or natural gas that you can process and sell, and the sulphur is just the inconvenient component that the law and your customers force you to remove. But at times when sulphur prices, as they have at the start of this January, reach levels as high as $300/t, then the industry standing joke is that sulphur suddenly stops being a by-product or waste product, and starts to become a ‘co-product’ instead.
