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.

Metso to supply copper smelter

Metso says it has won a €180 million order for the delivery of engineering and key process equipment for a new primary copper smelter investment at an undisclosed location in Asia. The planned production capacity of the copper smelter complex is 300,000 t/a of copper cathodes and 1.1 million t/a of sulphuric acid, based on licensed Outotec® Flash Smelting, PS Converting and Lurec® technologies. It includes the design and supply of key process equipment for the main areas of the smelter complex, and the gas cleaning and sulphuric acid plant, copper electrolytic refinery, and precious metals refinery. The delivery also comprises site services and spares.

Autoclaves arrive for Pomalaa HPAL project

PT Vale Indonesia Tbk says it has officially received the first two autoclave units for the Pomalaa high-pressure acid leaching (HPAL) project, a key component of the Indonesia Growth Project (IGP) Pomalaa. This delivery marks a critical milestone in preparing Indonesia’s high-tech nickel processing facility for operation. The welcoming ceremony was attended by PT Vale and PT Kolaka Nickel Industry (KNI) management, along with strategic project partners including Indonesia Pomalaa Industrial Park (IPIP), Huayou Southern Construction Command, MCC20, and other stakeholders.

Approval for phosphate expansion

Madhya Bharat Agro Products has announced board approval for a major capacity expansion at its Dhule manufacturing facility. The expansion represents a comprehensive enhancement of the company's fertilizer production capabilities, including 330,000 t/a of diammonium phosphate and NPK fertilizer, a 66,000 t/a phosphoric acid plant, and a 396,000 t/a sulphuric acid plant. The expansion plan is part of a strategy of vertical integration in fertilizer production. The addition of phosphoric acid and sulphuric acid production capabilities will support the primary DAP/NPK manufacturing operations, creating operational synergies and potentially reducing input costs, according to the company.
