Change is already here

One of the things that produced a lot of worried news headlines over the past couple of years is whether the energy transition is likely to lead to a shortage of sulphur as we switch away from fossil fuels on a large scale. As we’ve discussed in this magazine, those fears are overblown, certainly in the medium term future. Peter Harrison of CRU tackled the issue in his sulphur markets presentation at the recent Sulphur and Sulphuric Acid conference in New Orleans, and while he did admit to some reduction in sulphur supply from oil in the 2030s and increasing into the 2040s, increased sulphur recovered from sour gas is likely to more than make up for that at least until the 2040s. But one of the things that did strike me about his presentation is the extent to which the energy transition is indeed already changing the way that the sulphur market works, and will increasingly do so over the next few years.

Sulphuric Acid News Roundup

First Quantum Minerals Ltd. has contracted with MECS, Inc. (MECS), a subsidiary of Elessent Clean Technologies, for the Kansanshi smelter expansion at the Kansanshi mine at Solwezi. MECS’ scope of work will include a redesign of the existing sulphur-burning sulphuric acid plant into a copper smelter off-gas recovery sulphuric acid plant. This transition to a copper smelter off-gas recovery acid plant will enable First Quantum to reduce emissions from the existing copper smelter, increase production at the mine, and supply more copper to the global market, which will enable the adoption of greener technologies. MECS’ design for First Quantum incorporates proprietary technologies such as MECS® catalyst for low emissions and high conversion, Brink® mist eliminators, ZeCor® alloy towers and pump tank and UniFlo® acid distributor technology for operational reliability and efficiency.

Is a Black Sea deal back on the agenda?

While the world’s attention has been grabbed by the terrible situation in the Middle East, the Russian-Ukrainian conflict continues to drag on. Of particular concern in recent months has been the deal to allow export of grain from Odessa, which lapsed in July 2023, a year after it first began. The deal had allowed 33 million tonnes of grain to be exported, around 60% of it to the developing world. However, Russia had always insisted that continuing with the deal was contingent on (a) a resumption of Russian ammonia exports via Odessa and (b) removing SWIFT payment restrictions on the Rosselkhozbank agricultural bank, allowing easier export of fertilizer. Fertilizers remain exempt from sanctions on Russia, but the difficulty in securing payment, the closure of the ammonia pipeline to the Black Sea, and high maritime insurance rates for traversing the Black Sea have made exports much more difficult. And although Ukraine continues to export grain, now mostly via rail to ports like Ismail and Reni on the River Danube, Russia has done its best to disrupt this, striking ports and warehouses and laying mines in shipping lanes. Around 300,000 tonnes of grain has been destroyed, according to Ukraine, as well as up to three ships hit by mines and one possibly by a missile on November 8th. Furthermore, bottlenecks in rail transit and port capacity and the difficulty in getting ships to the ports mean that actual volumes of grain exported are considerably reduced, with only around 700,000 tonnes exported via the Danube Ports from August to the start of November.
