Core Pathways for Achieving Green and Low-Carbon Development in Phosphate fertilizer produciton process:
1. Process Upgrading and Energy Efficiency Improvement
Promoting the wet-process phosphoric acid production: Compared to the traditional thermal phosphoric acid process, the wet process reduces energy consumption by more than 30%, and the phosphorus recovery rate can reach over 95%.
2. Solid Waste Resource Utilization
Comprehensive Utilization of Phosphogypsum: Turning the byproduct phosphogypsum into building materials (such as gypsum board), using it as a soil conditioner or underground backfill material, achieving "turning waste into treasure" and reducing the risk of stockpiling pollution.
Other Solid Waste Recycling: Extracting elements such as fluorine and calcium from wastewater to develop value-added products.
3. Clean Energy Substitution and Low-Carbon Energy Application
Using renewable energy sources such as photovoltaics and wind power: Gradually replacing traditional coal and oil combustion to reduce carbon emissions. Improving overall energy efficiency through cascade utilization of thermal energy.
4. Intelligent and Digital Management
Introducing DCS, digital twins, and AI-optimized control: Real-time monitoring of energy consumption and emissions in fertilizer produciton lines, automatically adjusting process parameters, and achieving efficient and low-consumption operation throughout the entire process.
5. Policy Guidance and Green Management
Strict environmental regulations and carbon trading mechanisms: Encourage enterprises to implement clean production audits and improve their environmental management levels.
Capacity concentration and green industrial park construction: Optimize layout, achieve resource sharing, and centralized pollution control.
