Reg Adams of pigments and titanium dioxide consultancy Artikol reviews the demand for sulphuric acid in the manufacture of TiO2 , and the prospects for consumption over the next few years.

DuPont Clean Technologies has announced the successful startup and performance test of a 300,000 t/a STRATCO® alkylation unit licensed at the Hengli Petrochemical Company’s new refinery complex on Changxing Island in the Harbour Industrial Zone, China. The new alkylation unit enables Hengli to produce high-quality alkylate from a 100% isobutylene feed stream, catalysed by sulphuric acid. This first-of-a-kind unit was developed through DuPont research into the best ways to maximise product octane and minimise end point with this feedstock. Hengli had awarded DuPont the contract for the new alkylation unit as well as a MECS® sulphuric acid regeneration unit in 2015.

Legislation to control emissions of sulphur dioxide continues to tighten, via vehicle exhausts, and refinery and smelter emissions, leading to increased recovery of both sulphur and sulphur dioxide.

“T here are,” Mark Twain once remarked, “three kinds of lies: lies, damned lies, and statistics.” It’s certainly difficult to know what to make of economic statistics and indicators at the moment, in the world turned upside down that the Covid-19 pandemic has delivered. Here in the UK, we are told that April and May saw the national economy contract by 25%, the largest fall in 300 years of the Bank of England’s economic record keeping, and the situation is very similar across much of the developed world. But how real is that figure? After all, we were all sent home in March, to ‘lock down’ and prevent the spread of the virus, and we are only now starting to move back towards some semblance of normality. Some of us, fortunately or not, have still been able to work from home, but for much of the economy, especially for much of the service sector; tourism, travel, restaurants and hotels, theatres and cinemas – there has been zero activity. Remove half of the largest sector of the economy for three months and surely a 25% fall in output is exactly what you’d expect? But is that real, or just a number? Has that activity gone for good, or, now that we are emerging, blinking into the sunlight again, can we switch the economy back on again as easily as we switched it off?

Meena Chauhan , Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.

Sulphur demand losses for production of phosphoric acid are forecast at 2.2 million t/a in 2020. Factoring in demand gains in markets such as Morocco, the sector is expected to see a drop of 800,000 t/a in 2020. Recovery is forecast from 2021 with a 2 million t/a increase forecast.

There was a rapid increase in sulphuric acid demand for copper, uranium and nickel leaching from 1995-2015, but over the past few years growth in this sector has slowed dramatically. Now however there are signs that demand is starting to pick up again with several new projects under development.

Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.

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.
