Price Trends

At the end of August, the Qatar Chemical and Petrochemical Marketing and Distribution Company (Muntajat) tendered for 35,000 tonnes of sulphur for September loading from Ras Laffan, with offer prices reported at or around $130s/t f.o.b., according to market sources. Bids were received at multiple levels, with market participants initially anticipating awards around the mid-$120s/t f.o.b. The tender result was higher than market expectations and would equate to delivered prices to key Asian markets at $150-155/t c.fr. But prices in China and Indonesia remained lower this week at around $140-145/t c.fr, with India at $145-150/t c.fr. Prices have increased steeply since Muntajat’s 25 June session, which was indicated awarded in the mid-$80s/t f.o.b.. and Muntajat posted its Qatar Sulphur Price (QSP) for September at $125/t f.o.b., up $19/t from $106/t f.o.b. in August. This represents the highest QSP since March 2023 at $133/t f.o.b., and reflects delivered levels to China nearing $150/t c.fr at current freight rates. Tight supply and strong downstream demand have pushed tender prices higher. Muntajat tenders were previously awarded at $92/t f.o.b. in April, up from $88/t in March and the low $80s/t f.o.b. in February.

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.

Channelling in SRU converters

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.
