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.

Muntajat announced its QSP for September at $125/t f.o.b., an increase of $19/t from its August price. This was following its tender earlier this week, which market sources indicated to have achieved at or around $130s/t f.o.b. Over the past two weeks, KPC in Kuwait closed two sales tenders, with both indicated awarded in the high $120s/t f.o.b. Middle East spot f.o.b. prices are at their highest level since March 2023 and have climbed 58% over the past two months.

Transporting sulphur as a dry bulk solid can lead to it breaking into small particles which create dust. Over the years, various forming processes have been developed to try and minimise dust formation and produce the strongest, most resilient formed sulphur particles.

In this case study, CS Combustion Solutions presents a comprehensive strategy for the capacity enhancement and optimisation of a sulphuric acid plant that was facing several operational challenges.

This troubleshooting case study describes an incident at one of the sulphur recovery units at BPCL Kochi Refinery, India. Following a maintenance turnaround of the unit in 2022, unusually high H2 S and SO2 were observed at the outlet of the Claus section. This created an additional load on the tail gas reactor, which led to frequent plugging in the quench column and frequent outages in the tail gas unit, creating environmental and reliability issues in the unit. The activities to identify the root cause of the incident are described and the measures to solve the problem are shared.

Veolia says that its subsidiary Veolia North America has signed an agreement for the divestment of Veolia North America Regeneration Services, which includes its sulphuric acid and hydrofluoric acid regeneration activities for refineries, to private equity firm American Industrial Partners for $620 million. These activities represented revenues of around $350 million in 2023. The financial closure of the transaction is expected soon. Veolia’s Sulphuric Acid Regeneration Business includes its sulphuric acid and potassium hydroxide regeneration, as well as sulphur gas recovery, and sulphur-based products production businesses.

China’s acid production continues to grow as new smelters come on-stream. But high domestic demand from phosphate production as export restrictions are lifted and a shortage of copper concentrate may limit the potential for acid exports.

Optical gas imaging technology, enhanced by artificial intelligence, offers a groundbreaking approach to monitoring SO2 emissions in real time. Andrés Russu of SENSIA introduces SENSIA’s RedLook solution which offers fully autonomous, 24/7 continuous monitoring of SO2 leaks, providing industries with the tools they need to maintain environmental integrity and operational safety.

Saudi Aramco has sold another tranche of 1.54 billion shares, amounting to 0.64% of the company’s total ownership. The sale, at 27-29 riyals per share, was oversubscribed by a factor of five, making it more popular than the previous IPO, in 2019, which sold 1.5% of the company’s shares for a total of $29.4 billion. Foreign take up of shares was also higher this time, with more than half of sales to foreign investors, compared to 23% for the 2019 sale. However, it remains relatively small in scale compared to Saudi Arabia’s ambitions as part of its Vision 2030 plan to encourage more foreign direct investment and wean the country off its dependence on oil. Aramco is the world’s largest oil company in terms of both daily crude production and market cap, and remains 82% in the hands of the government and 16% held via the country’s sovereign wealth fund, the Public Investment Fund (PIF).
