Chloride Preparation TRIZ Cases
- Hydrothermal Plastic Separation for High-Purity Recycling
Superheated water separates light and heavy plastics, removes contaminants, and produces a light fraction with at least 95 wt% purity.
- Superheated Water Dechlorination for Chlorinated Plastic Recycling
Superheated water dechlorinates plastic at acidic pH, keeping HCl dissolved while producing material suitable for recycling.
- Hydrohalite Decomposition for Fine, High-Surface-Area Salt Crystals
This case uses warm saturated brine to decompose hydrohalite, producing fine NaCl crystals with high surface area and lower energy use.
- In-situ Chloride Formation in Titanium Dioxide Pigment Production
Reacting metal alloys with chlorine gas forms chlorides for titanium dioxide, eliminating hazardous material handling and expensive facility requirements.
- Vertical Three-Zone Reactor for KCl-NaCl Separation
A vertical three-zone reactor separates potassium chloride and sodium chloride from sylvinite ore using integrated dissolution, flotation, and countercurrent washing.
- CO2 Removal via Hydroxide Electrolysis and Mineralization
Electrolyzed hydroxide captures carbon dioxide from waste streams, generating saleable carbonate products that offset high capital costs.
- Selective Chlorination of Metal Oxide Waste for High Purity Recovery
Selective chlorination converts calcined metal oxides into volatile chlorides, enabling high purity separation from low-grade industrial waste.
- High-Purity Vanadium Tetraoxide Production via Low-Temperature Chlorination
Fluidized bed chlorination and rectification purify vanadium oxytrichloride, reducing production costs and wastewater pollution.
