SO2 emissions control
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.

On June 30th, following clearance from the European Commission, Outotec completed the year-long merger of Metso’s Minerals business with Outotec via a partial demerger of Metso. The newly formed company, Metso Outotec, will focus on leadership in sustainable minerals and metals processing and recycling technologies. Headquartered in Finland, Metso Outotec employs over 15,000 professionals in more than 50 countries and its combined sales for 2019 were e4.2 billion.
“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.
Shell Global Solutions International BV (Shell) has awarded Worley two contracts for PT Pertamina EP Cepu’s (PEPC) new sulphuric acid plant in Indonesia. This plant is part of the Jambaran-Tiung Biru utilised gas field project for PEPC, which is a subsidiary of PT Pertamina-Indonesia’s state-owned energy company. Under the contracts, Worley will supply be supplying Chemetics’ cooled oxidation reactor (CORE) technology. This is the first time that CORE will be paired with Shell’s Cansolv SO2 capture technology. Worley gained the Chemetics technology as part of its Jacobs Energy, Chemicals and Resources acquisition last year. Cansolv controls the emissions and captures additional by-product value from the sulphur dioxide emitted from various refinery flue gas streams (such as cracking units, process heaters and boilers), sulphur plants and spent acid regeneration units. Sulphur dioxide can be recycled to the sulphur recovery unit to be produced as marketable sulphur or converted to sulphuric acid.
We highlight recent innovations in sulphuric acid plant design and construction. NORAM and CPPE are offering a new hybrid sulphuric acid process. KVT, meanwhile, has upgraded its wet sulphuric acid technology to reduce capex, opex and emissions. Improved methods of construction and new materials from Koch Knight are also helping to optimise acid tower design
