Bicarbonate Preparation TRIZ Cases
- Recycled Carbon Material Processing for Lithium Removal
A two-stage ethylene carbonate heat treatment converts residual Li into lithium carbonate, yielding higher-purity recycled carbon material.
- Lithium Compound Dissolution via Carbonic Acid for Scrap Recovery
Carbonate-fed carbonic acid converts poorly soluble lithium compounds into lithium hydrogen carbonate, improving scrap recovery and purity.
- Sequential Crystallization for Sodium Bicarbonate Alkali Recovery
A sequential crystallization process recovers alkali from sodium carbonate purge streams to produce saleable crystals.
- Sulfide Removal from Alkali Solutions via Hydrogen Peroxide Oxidation
Hydrogen peroxide oxidizes sulfides in aqueous alkali solutions to soluble products, preventing hydrogen sulfide emissions during bicarbonate decomposition.
- Waste Solid Purification for Soda Ash Production
Selective leaching removes sodium chloride and silicates from waste solids, preventing equipment scaling during soda ash production.
- Alkali Metal Bicarbonate Particle Size Control via Additive Crystallization
Additives modify alkali metal bicarbonate crystallization to adjust particle size and specific weight by flow.
- Sodium Carbonate Production via Electrodialysis and Chemical Conversion
Dissolving fine sodium carbonate particles enables electrodialysis to generate sodium hydroxide for reacting with mineral ore.
- Ion Exchange Resin for Lithium Extraction from Brine
Ion exchange resin separates lithium from sodium contaminants in brine, boosting conversion rates while reducing energy consumption.
- Sodium Bicarbonate Production via Alkali Recovery
A sodium bicarbonate production process recovers alkali from mother liquor to minimize purge volumes.
- Zinc-Based Syngas Production from CO2 and Water
A chemical process using zinc to convert water and carbon dioxide into hydrogen and carbon monoxide.
- Caustic Soda Synthesis for CO2 Absorption
Caustic soda synthesis using natural ore and slaked lime reduces energy consumption while absorbing carbon dioxide from combustion exhaust.
- Lithium Fluoride Crystallization via Purified Bicarbonate
Converting low-grade carbonate to soluble bicarbonate enables simple impurity removal, reducing production costs while maintaining battery-grade purity.
- Sodium Hydroxide CO2 Capture with Calcium Oxide Mediator
Calcium oxide mediates sodium carbonate regeneration at low temperatures, avoiding high-energy direct decomposition.
