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.

Manyar smelter faces supply issues

Freeport Indonesia may be forced to suspend operations at its Manyar smelter at the end of October due to a lack of copper concentrate, according to local press reports. The news follows the mudslide at the Grasberg mine in September, which killed seven workers. Grasberg, which represents almost 3% of global copper mine production, has halted production and Freeport says that it may not return to pre-accident operating rates until 2027. Stocks of copper concentrate at Grasberg were estimated to be only sufficient to operate the Manyar smelter until the end of October. The $3.7 billion Manyar smelter only resumed operations in May after a fire broke out in October last year, damaging the plant.

Government to limit new nickel projects

The Indonesian government has moved to limit new licenses for nickel projects in an attempt to correct overdevelopment of the industry and the subsequent crash in global nickel prices. The permit restriction applies to new nickel processing companies that produce intermediate products, both with pyrometallurgical (RKEF) and hydrometallurgical (HPAL) technologies. Currently, Indonesia already has 54 nickel processing plants operating, 38 in the construction stage, and 45 are still under planning.

Paradeep plans additional phosphoric acid capacity

Paradeep Phosphates Ltd (PPL) has announced a $400 million capacity expansion program, following its October 13th merger with Mangalore Chemicals & Fertilizers Limited (MCFL). This company says that the move aims to strengthen PPL's market position and enhance its production capabilities. The investment will involve increasing granulation capacity by 1.0 million t/a at the Paradeep site, as well as an additional 250,000 t/a of phosphoric acid and 750,000 t/a of sulphuric acid capacity at the company’s new Mangalore site. The expansion is expected to be completed within three years, according to PPL, and is expected to ensure 100% backward integration for fertilizer production, reduce import dependency, and enhance operational capabilities and profitability. low-contaminant phosphate concentrate that allows for easy conversion into purified phosphoric acid. The company has spent over C$100 million advancing the project and has received funding and investment from the Quebec Government.
