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.

BHEL to supply syngas purification plant

Bharat Heavy Electricals Ltd says that it has secured a $305 million contract from Bharat Coal Gasification and Chemicals Ltd (BCGCL) for a syngas purification plant at Lakhanpur, Odisha. The lump sum turnkey package includes design, engineering, equipment supply, civil works, commissioning and 60-month operation and maintenance services. The project, part of BCGCL's planned 2,000 t/d ammonium nitrate facility, has a 42-month execution timeline. BCGCL is a joint venture between Coal India Ltd, with a 51% stake and BHEL with a 49% shareholding.

Government moving forward with coal-based urea plant

The government of Pakistan has published a ‘strategic roadmap’ for the country’s major Coal-to-Fertiliser (C2F) initiative. The project is being executed by the publicly-owned Fauji Fertiliser Company (FFC), and will use local coal reserves at Thar as feedstock for the ammonia plant, which will in turn feed 720,000 t/a of urea capacity. The $1.1 billion project aims to strengthen the country’s fertiliser security as well as add value to local resources. A bankable feasibility study was completed in November 2025, and the project is now in the Front-End Engineering Design (FEED) and project agreements phase. Under the proposed timeline, financial closure is expected between late 2026 and 2027, while commercial operations are targeted to commence in January 2031.
