How does inventory change impact sulphur availability and pricing?

In the last two years there have been significant changes to the level and location of sulphur inventory, which has caused swings in short-term supply availability. Inventory plays a necessary role in balancing the sulphur market but exactly when, where, how, and why inventory enters the market can trigger a diverse range of price responses. In this insight article, CRU’s Peter Harrisson looks at how inventory change influences sulphur availability and pricing.

Full speed ahead for Indonesian nickel

One of the biggest areas for new sulphuric acid demand in the past few years has been in nickel processing plants, particularly in Indonesia. A decade ago, incoming president Joko Widodo took a strategic decision that the country needed to try and capture more of the value chain from its mining and mineral industry, which was focused at the time on exports of aluminium, copper and nickel ores and concentrates, mainly to China. Over the past 10 years, the export of raw ores has been progressively restricted and companies instead compelled to build downstream processing plants for the metals. With China the main recipient of Indonesian ores, much of the investment in metals processing in Indonesia has been via Chinese companies.

Enhancing sulphuric acid production

In this case study, Florian Kistl of CS Combustion Solutions presents a comprehensive strategy for the capacity enhancement and optimisation of a sulphuric acid production plant that was facing several operational challenges that were hindering its efficiency and reliability. As a result of a series of targeted optimisations, including the innovative use of ultrasonic nozzles and CFD modelling, downtime and maintenance costs were reduced, and a substantial capacity increase was achieved.

Boosting sulphuric acid production with oxygen

A plant operating a spent acid decomposition furnace as part of its sulphuric acid production facility desired to increase acid production primarily by processing additional spent acid while making minimal modifications to the plant equipment and operations. The Messer solution entailed introducing oxygen in two steps, both as an enrichment to the combustion air and by direct injection into the furnace. The resulting performance improvements exceeded the project objectives for acid production and spent acid decomposition, without increasing NOx emissions. This paper provides a summary of the system start-up and tuning and presents the resulting improvements and lessons learned.
