Pulping With Inorganic Bases TRIZ Cases
- Oxidized Kraft Lignin Production With Sodium-Sulfur Recovery
Oxidizing unwashed kraft lignin with white liquor and membrane filtration enables in-mill surfactant production while preserving sodium and sulfur balance.
- Black Liquor Filtration and Lignin Recovery for Lower-Energy Pulping
Multi-stage filtration, lignin precipitation, and electrodialysis cut black liquor recovery energy while separating reusable sodium chemicals.
- Pulp Digestion Accelerator Composition for Faster Lignocellulose Breakdown
A quaternary ammonium, amine, and sulfide-generating accelerator speeds lignocellulose digestion to raise pulp output with less wood use.
