MHI successfully produces hydrogen at ammonia cracking pilot plant

Mitsubishi Heavy Industries says that it has succeeded in producing 99% pure hydrogen by cracking ammonia using steam as the heating source. The production of hydrogen at pilot scale using the steam heating was conducted at the company’s pilot plant in the Nagasaki District Research & Innovation Centre, marking a world first. By contrast to technologies that use heat from burner combustion, MHI’s steam heating system operates at lower reaction temperatures, reducing operating costs. In addition, because a combustion furnace is not required, the system offers excellent features such as the potential for miniaturisation.

MHI aims to build on this achievement to promote the development of medium-scale, decentralised ammonia cracking systems near hydrogen demand sites. Based on the results of this pilot test, MHI, in collaboration with project partners Nippon Shokubai Co., Ltd. and Hokkaido Electric Power Co., Inc., will accelerate the development of this technology, which was selected by Japan’s New Energy and Industrial Technology Development Organization (NEDO) for its “Development of Technologies for Building a Competitive Hydrogen Supply Chain” project.

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.
