Chlorine/Hydrogen-Chloride TRIZ Cases
- Hydrochloric Acid Hydrogen Production Using a Metal Alloy Electrode
A metal alloy electrode drives electron flow in hydrochloric acid solution to produce hydrogen with lower energy use and minimal CO2 emissions.
- Nuclear Fuel Salt Chlorination with Selective Chlorine Recovery
Selective adsorption traps recover high-purity HCl, Cl2, and CCl4 from fuel salt chlorination gas, cutting chlorine-37 loss and cost.
- L-Ergothioneine Salt Crystals for Stable Purification and Formulation
Salt and crystalline forms of L-Ergothioneine improve stability and purification, supporting easier formulation for food, medicine, and cosmetics.
- Halogen-Mediated Hydrocarbon Decomposition for Hydrogen and Carbon
Halogens decompose hydrocarbons into hydrogen and solid carbon at lower temperatures, while recycling reduces heat demand and reactor constraints.
- Low GWP Sulfur Fluoride Hydrogen Dielectric Gases
Replacing fluorine with hydrogen in sulfur hexafluoride reduces global warming potential while maintaining arc quenching capability.
- Retarded Mineral Acid Composition for Oilfield Carbonate Stimulation
Amine fixing agent slows mineral acid reaction with carbonate rock to enable deeper reservoir penetration.
