In the field of fertilizer engineering, particularly in compound fertilizers and Mannheim process potassium sulfate, we possess outstanding design advantages with a professional team of over 50 members. Representative projects include: a 200,000-ton/year new compound fertilizer project, two 200,000-ton solid microbial agent projects, a 200,000-ton potassium sulfate project, a 160,000-ton/year potassium sulfate project, and a 20,000-ton high-efficiency potassium fertilizer project. Additionally, we have conducted safety diagnosis and review engineering for large-scale phosphate and compound fertilizer integrated units, covering 280,000 tons of sulfuric acid, 120,000 tons of sulfuric acid, 150,000 tons of phosphoric acid, 300,000 tons of diammonium phosphate (DAP), and a complex unit comprising 1 million tons of sulfuric acid, 300,000 tons of phosphoric acid, and 400,000 tons of DAP. For major agricultural demand countries along the Belt and Road Initiative, we provide full-process design services for fertilizer projects ranging from feasibility studies to construction drawings, and can integrate upstream technologies from phosphate and potassium chemical industries to form comprehensive solutions.
