Casale wins melamine contract

Casale wins melamine contract

Casale has been awarded a contract to supply melamine technology by Anhui Haoyuan Chemical Group. The new melamine plant will feature Casale’s uLEM-N technology, with a design capacity of 60,000 t/a, and will be fully integrated into an urea plant operated by Anhui Haoyuan. This is the third project that the two companies have developed together, following the successful implementation of two 1,500 t/a ammonia synthesis loop plants based on Casale’s N-LOOP™ technology.

Casale says that its uLEM-N melamine process introduces a significant shift in sustainable design by eliminating caustic soda usage entirely, thanks to ammonia-based purification, and features a highly efficient and proven high-pressure synthesis section using proven urea-based off-gas scrubbing. It operates with a zero liquid discharge approach, and integrates simply with urea plants, reducing capex.

Casale has also recently noted the successful conclusion of performance tests by the new 1,200 t/d coal-based ammonia plant owned and operated by Jiangsu Debang Xinghua Chemical Technology Co., Ltd., located in China’s Jiangsu Province. Commissioned in June 2024, the plant features Casale’s proprietary ammonia synthesis loop, which has reached 110% of capacity shortly after start-up and operated stably at 130% load for extended periods, with no bottlenecks encountered in the synthesis loop.

“We are extremely proud of the trust placed in us by Jiangsu Debang Xinghua Chemical Technology Co., Ltd. and pleased to see our technology making a real difference in performance. This achievement underscores our commitment to delivering cutting-edge solutions that help our customers meet and exceed their production targets” said Casale CEO, Federico Zardi.

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.

METI funds hydrogen for steel and ammonia production

As part of the Japanese government’s Green Transformation scheme, two hydrogen producers have been selected to receive subsidies for low-carbon production projects. Out of the overall $1 trillion GX scheme, $51 billion is earmarked for hydrogen and ammonia investments, with the bulk going towards a long-term programme that subsidises the increased production costs. The first two recipients are a Toyota Tshuho-led consortium (electrolytic hydrogen for steel), and Resonac (hydrogen from used plastics for ammonia). In the programme, production projects are required to have the support of a major hydrogen consumer – in Resonac’s case, this is Japanese chemicals giant Nippon Shokubai, who will offtake the ammonia produced from lower-carbon hydrogen.
