Sittard, The Netherlands — Stamicarbon, the nitrogen technology licensor of NEXTCHEM (MAIRE Group), has been awarded licensing, process design package (PDP), and proprietary equipment supply based on its proprietary NX STAMI™ Urea technology, for a new urea plant in China by Shandong Lianmeng Chemical Company.

The plant will adopt Stamicarbon’s Ultra-Low Energy design. This solution, part of the proprietary NX STAMI™ Urea series, enables a 35% reduction in steam consumption and a 16% decrease in cooling water usage compared to conventional methods, thanks to innovative high-pressure steam utilization and advanced pool reactor design. The process also ensures very low biuret content in the final product and high-quality prills, thanks to Stamicarbon’s prilling tower design.

Key equipment, including the pool reactor and stripper, will feature E-type super duplex stainless steel, leveraging Stamicarbon’s expertise in material science and industrial applications.

“The progress of our first Ultra-Low Energy urea plant currently under construction, together with our successful collaboration with Stamicarbon, has been very positive,” a representative of Shandong Lianmeng Group commented. “Based on this experience, we are confident in investing in a second plant using the same technology.”

"This contract further strengthens our long-standing presence in China and the partnership with Shandong Lianmeng Group. This award demonstrates the trust of our clients in our Ultra-Low Energy urea technology which sets a benchmark for energy efficiency and reliable large-scale urea production," said Pejman Djavdan, Managing Director of Stamicarbon.

This project marks the tenth global application of Ultra-Low Energy technology and the eighth in China, with seven plants already in operation.
