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

Copper major Freeport-McMoRan is reportedly on verge of finalising a $2.8 billion deal with China’s Tsingshan to build a copper smelter in Weda Bay, Indonesia. The Indonesian government said that the companies were aiming to conclude negotiations by the end of March. It also said that most of the financing will be borne by Tsingshan, with Freeport possibly only needing to provide funding for 7.5% of the total project cost. The smelter would have a copper concentrate input capacity of 2.4 million t/a.

The coronavirus outbreak necessitated a ‘virtual’ CRU Sulphur + Sulphuric Acid conference last year, held in November 2020.

Selecting the right catalysts for the SO2 converter in a sulphuric acid plant has always been about balancing expenses, gains, and compliance. With increasing demands for sustainability and in challenging economic times, operators need to adjust their plants to get even more from less. This has led to market demand for new catalytic solutions that offer better productivity and a lower climate footprint, all at the lowest cost possible. Catalyst design and formulations continue to evolve with Haldor Topsoe, DuPont Clean Technologies and BASF all adding new types of sulphuric acid catalysts to their portfolios.

The global pandemic and new wave of lockdowns in some regions continue to pose a level of uncertainty to oil demand and in turn sulphur recovery. There are positive signs in the macro economic picture on the back of the vaccine rollout but significant question marks remain.

Metal markets are used to ups and downs, and, as we discuss elsewhere in this issue, this year has seen more than most, mainly thanks to the virus that is still keeping us indoors – as I write this, the UK has just moved back into a second national ‘lockdown’. However, this year has seen the fortunes of one metal in particular simply rise and rise – nickel.

Although 2019 had been a volatile year for acid markets, with shutdowns disrupting supply, the coronavirus outbreak wrought even more havoc in 2020, across both supply and demand.

Production cuts globally at refineries have left supply tight heading into the fourth quarter, firming prices. This has been compounded by major exporters in the Middle East prioritising sulphur tonnes to contracts before spot sales.

Several highly corrosion resistant materials are available today for use in handling process fluids encountered in the production of concentrated sulphuric acid. These alloys, properly selected for the operating conditions, provide the benefits of long operating life under harsh operating conditions extending the period of uninterrupted production cycles and lowering the incidence of catastrophic equipment failure. In this article, M. J. Cooke of Weir Minerals discusses materials of construction for pumps, valves and piping used in the production of sulphuric acid.
