Pulp Liquor Regeneration TRIZ Cases
- Centralized Sorting Control for Dynamic Facility Reconfiguration
Real-time feedback lets one facility retune sorting devices at another, reducing manual retuning while improving sorting accuracy and throughput.
- Sorting Facility Reconfiguration for Jam-Responsive Accuracy Control
Centralized feedback control reconfigures sorting equipment after jams or stream changes, improving accuracy and reducing manual retuning.
- Sorting Facility Reconfiguration Using Feedback and Layout Data
Feedback-driven control reconfigures sorting devices by layout position to handle jams and shifting material streams with less manual retuning.
- Multi-Component Defoamer Feed Control for Adaptive Foam Intervention
Online sensors and ML adjust individual defoamer components in real time to control foam while cutting excess chemical use.
- Delignified Wood Molding for Strong 3D Components
Delignified wood chips are thermomechanically compacted into complex 3D parts, combining high strength, low weight, and binder-free sustainability.
- Fluidized-Bed Caustic Recovery With Calcium Carbonate Pellet Growth
A fluidized-bed crystallizer grows larger calcium carbonate pellets to cut lime mud fouling, improve dewatering, and recover caustic more efficiently.
- Branched Siloxane Antifoam Compositions via Radiation Crosslinking
Radiation crosslinking branches non-functionalized organopolysiloxanes to control viscosity and improve foam suppression without platinum catalysts.
- PCC Production Using Processed Lime Mud to Lower Specific Surface Area
Controlled lime mud particle size and carbonation produce lower-SSA PCC, reducing sizing chemical use and improving printability.
- Acid Retardation Resin for Sulfuric Acid Recovery from Biomass Hydrolysate
Fixed-bed acid retardation resin recovers sulfuric acid from biomass hydrolysate, eliminating lime neutralization waste and enabling direct acid recycling.
- Green Liquor Clarification via Dregs Recirculation and Flocculation
Recirculating dregs through turbulence generators breaks particles into smaller fractions to enhance sedimentation rate in green liquor clarification.
- Pulp Tower White Water Separation for Effluent Reduction
Diverting excess white water into a second pulp tower where it separates from pulp reduces effluent volume and water consumption.
- Green Liquor Recausticization Carbon Dioxide Addition
Adding carbon dioxide during dilution converts residual calcium oxide into calcium carbonate, preventing sedimentation and ring formations in lime kilns.
- Continuous Digester Inclined Separator Black Liquor Heating
Inclined separator uses black liquor circulation to heat lignocellulosic feed, reducing reject levels and bleaching chemical consumption.
- In-line Drainer Screen Basket Curved Slot Edges
Curved inlet edges on slanted screen basket slots prevent solid material lodging in black liquor slurry streams.
- Cellulose Carbamate Production via Integrated Pulp Mill Urea Recycling
Integrating microcrystalline cellulose and carbamate processes in a pulp mill minimizes nitrogen emissions by converting released ammonia back into urea.
- Catalyst Recovery via Hydrophobic Adsorbent Particles
Hydrophobic adsorbent particles concentrate dilute catalyst over 30-fold for reuse while minimizing solvent volume.
