Ammonium Nitrates TRIZ Cases
- Method for preparing cathode active material precursor for secondary battery, and preparation apparatus using same
Filtrate recycling removes ammonia and sodium sulfate while recovering metal ions, cutting wastewater in cathode precursor production.
- UAN Production From Ammonium Nitrate Waste With pH-Controlled Recovery
pH-controlled evaporation and scrubbing convert dilute ammonium nitrate waste into UAN while recovering nitrogen compounds and limiting corrosion.
- Static-Mixer Ammonium Nitrate Reactor for Low Ammonia Slippage
Upstream and downstream static mixers improve ammonium nitrate reactor mixing to cut ammonia slippage, nitrogen losses, and energy use.
- UAN Production from Small Ammonium Nitrate Waste Streams
pH control and vapor scrubbing turn small ammonium nitrate waste streams into UAN while recovering nitrogen compounds and lowering emissions.
- Two-Loop Ammonia Scrubbing for Concentrated Ammonium Nitrate
Separate nitric acid generation and ammonia capture loops improve scrubbing safety while producing concentrated ammonium nitrate.
- Integrated Ammonia–Nitric Acid Process With Ammonia Buffering
Mode switching stores excess ammonia during high renewable power and sustains nitric acid production during low-power periods.
- Integrated Urea Production for Low-Biuret DEF and UAN
This case integrates aqueous DEF and UAN production, recycling ammonia while avoiding evaporation and wastewater treatment.
- Sodium Bicarbonate Regeneration for Sulfur Oxide Removal
A regenerative method converts sulfur oxides into sodium sulfate using sodium bicarbonate under oxidizing conditions.
