Process Efficiency Improvement TRIZ Cases
- Metal Recovery from Organic Secondary Materials
Preprocessing organic secondary materials enables continuous thermal treatment, maintaining high throughput while minimizing pollutant emissions.
- Phosphoric Acid Recovery from Sewage Sludge Ash via Segmented Leaching
Segmented leaching at varying pH levels extracts phosphoric acid from sewage sludge ash, resolving low-grade product issues by enabling technical grade purity.
- Copper Recovery from Chloride Media Using Sulfate Ion Mediation
Adding sulfate ions to chloride media solvent extraction increases copper concentration in the organic phase, reducing solution volume and operational costs.
- Mongrel Alloy Correction for Amorphous Metal Feedstock
Corrects contaminated mongrel alloy composition using specific elements to achieve amorphous structure without virgin material.
- Non-ferrous Slag Processing via Flux-Assisted Reduction
Flux-assisted reduction converts iron and volatile metals in non-ferrous slag to metallic form for clean separation.
- Spent Inert Anode Thermal Treatment for Bronze Casting
Thermal treatment of spent inert anodes at 950-1200°C removes bath residues, preventing voids and iron content reduction in castings.
- Rare Earth Recovery via Reducing Agent and Direct Oxalate Precipitation
Direct oxalate precipitation with a reducing agent isolates rare earth elements from acidic leach solutions.
- Two-Stage Scrap Metal Melting Combustion
A two-stage combustion process heats solid scrap with visible flames before switching to flameless mode for molten metal.
- Tin Stripping Additive with Corrosion Inhibitors
Tin stripping additive reduces nitric acid usage while maintaining high efficiency, addressing environmental pollution from strong acid waste.
- Evaporation Process for Noble Metal Recovery from Waste
Evaporation process separates organic solvents from noble metals in liquid waste streams.
