Study on ammonia fuel storage tanks and transportation equipment

Shipping classification society ClassNK has formed a consortium with IHI Corporation, JFE Steel, Tohoku University, and Institute of Science Tokyo to participate in Japan’s Feasibility Study Program on Energy and New Environmental Technology. The consortium will promote the development of stress corrosion cracking (SCC) probability evaluation tools for fuel ammonia storage tanks and transportation equipment. Initially, the consortium will conduct a detailed study of the SCC mechanism involved in steel cracking due to the combined effects of mechanical stress and corrosion caused by liquid ammonia. Thereafter, the consortium plans to develop tools for easily and accurately assessing SCC probability. Finally, opinions will be solicited from stakeholders to formulate risk-based maintenance procedures for fuel ammonia storage and transportation facilities, and marine fuel tanks ultimately to promote the expanded use of fuel ammonia.

Coromandel starts trial operations at new acid plants

Coromandel International says that it has started trial production at its new sulphuric acid and phosphoric acid plants in Kakinada, Andhra Pradesh. The company says that this marks a crucial step towards transforming the unit into a fully integrated facility, significantly enhancing production capacity and diminishing reliance on imported raw materials for fertiliser manufacturing. The company is now focusing on a phased ramp-up. The new plants have of 2,000 t/d of sulphuric acid and 650 t/d of phosphoric acid, respectively. The integration of these acid plants is strategic, aligning with Coromandel's objective to strengthen backward integration in its fertiliser manufacturing value chain. By producing key intermediates in-house, the company aims to secure stable supplies, enhance cost efficiencies, and achieve greater self-sufficiency, thereby reducing dependence on imported raw materials. The project aims to replace over 50% of the Kakinada plant's imported acid requirements and mirror the integration levels seen at its Vizag and Ennore facilities.

Indonesian nickel shutdown to cut sulphur/acid demand

Four Chinese-operated nickel plants at the Indonesian Morowali Industrial Park have temporarily ceased operations following a fatal landslide in February, in a development that will significantly reduce regional demand for sulphur and sulphuric acid. The shutdowns affect facilities run by China’s GEM Co. and its partners, which together account for 30% of Indonesia’s high-pressure acid leaching (HPAL) capacity. The move comes amid heightened regulatory scrutiny. The largest of the four plants, PT QMB New Energy Materials, could remain offline for up to three months.

NCOC seeks arbitration over sulphur fine

The North Caspian Operating Company (NCOC), which operates the huge Kashagan oil field in Kazakhstan, has said that it is seeking international arbitration to resolve its ongoing dispute with the government of Kazakhstan. Kazakhstan has imposed a swingeing $4.6 billion fine for alleged violations of sulphur storage regulations at the NCOC site. In December, a special administrative court in Astana turned down an appeal by NCOC, although it also granted leave to appeal in a higher court. NCOC, a partnership between Shell, Eni, TotalEnergies, ExxonMobil, China National Petroleum Corporation, Inpex and Kazakh state oil and gas company KazMunayGaz, continues to maintain that its sulphur handling operations have been conducted in compliance with Kazakhstan’s laws and that it had the required permits in place.
