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.

Methanol from biomass

Chinese electrolyser manufacturer LONGi Green Energy has begun construction on a $325 million green methanol project in Inner Mongolia that will combine biomass gasification with hydrogen from the company’s electrolysers. The project, being developed at the Urad Rear Banner Industrial Park, will process 600,000 t/a of agricultural waste to produce 190,000 t/a of green methanol in the first phase. Phase 2 will expand ethanol capacity to 400,000 t/a, with hydrogen coming from new electrolysers powered by 850 MW of wind and 200 MW of solar power. LONGi says that the project will cut carbon dioxide emissions by 1.2 million t/a, while adding more than 1 GW of wind and solar capacity to the region’s energy mix.

Joint venture for green ammonia project

L&T Energy GreenTech Ltd (LTEG), a wholly-owned subsidiary of Larsen & Toubro (L&T), has entered into a joint development agreement with Japan’s Itochu Corporation of Japan to develop and commercialise a 300,000 t/a green ammonia project at Kandla in Gujarat state. Under the agreement, LTEG and Itochu will collaborate on the development of the green ammonia facility, with Itochu planning to offtake the product for bunkering applications in Singapore.

Ammonia-urea plan for Chechnya

The Chechen Republic’s Ministry of Industry and Trade is reportedly in discussions with Chinese company Wuhuan over the construction of a mew nitrogen fertilizer plant in the region. Wuhuan is being considered as a potential EPC contractor, with technology and design coming from Russian design agency JSC GIAP. A site in the republic’s Naursky district has been earmarked for the project, which aims to produce 1,700 t/dm of ammonia and 3,000 t/d of urea. Development and construction is expected to take five years, with plant startup currently scheduled for the first half of 2030. The total cost of the project is estimated at $2.4 billion.
