Pulp By-Products Recovery TRIZ Cases
- Lignin Separation from Black Liquor via Two-Stage Acidification
Segmented acidification with a storage phase grows lignin particles, resolving poor filterability and high fresh chemical usage in black liquor processing.
- Plant Tissue Composition Enhances Saccharification Yield
Plant tissue composition supplies endogenous cellulases to increase fermentable sugar yields, reducing the need for expensive exogenous enzyme additions.
- Paper Mill Sludge Carbonation for High-Purity Calcium Carbonate
Acid-treated paper mill sludge eluate captures carbon dioxide to precipitate high-purity calcium carbonate.
- Lignin Bioash Concrete for Carbon Sequestration
Lignin bioash concrete sequesters carbon dioxide through carbonation reactions, reducing embodied emissions while maintaining structural integrity.
- Lime Mud Recycling via Pulverization and Hydration
Burning and hydrating lime mud converts waste into high-whiteness raw material, resolving the contradiction between treatment complexity and reuse potential.
- Black Liquor Hydrothermal Carbonization Lignin Separation
Hydrothermal carbonization upgrades black liquor lignin to solid carbon, simplifying extraction and reducing ash impurities.
- Cellulose Nano Crystal Production from Paper Sludge
Acid hydrolysis and enzymatic treatment extract high-purity cellulose nano crystals from paper mill sludge, eliminating complex deinking waste disposal.
- Lignin Separation from Black Liquor via Na/S Balance Control
Recycled precipitator dust controls ionic strength during washing to reduce acid consumption and prevent filter cake plugging.
