Fractional Distillation TRIZ Cases
- Multiple Downcomer Tray Segmentation for Uniform Liquid Flow
Anti-jump plates segment a multiple downcomer tray to prevent inhomogeneous liquid flow, ensuring consistent gas-liquid ratios and improved tray efficiency.
- Vapor-liquid contact tray with tilting canopy cover
Support-area-aeration apertures and a tilting canopy cover redirect vapor flow over tray supports, increasing capacity by 5-25% while reducing pressure drop.
- Natural Circulation Reboiler for Stable Acrylic Acid Recovery
A natural circulation reboiler heats waste liquid through heat exchanger tubes to drive continuous vaporization.
- Acetonitrile Separation via Vacuum Distillation and HCN Removal
Reduced pressure distillation overcomes azeotrope formation with methanol, water, and allyl alcohol to isolate high-purity acetonitrile.
- De-entrainment Device for Mass Transfer Column Tray
Separate deflector members mounted via vertical legs prevent cracking in brittle materials while increasing tray capacity by up to 18 percent.
- Solvent Purification Segmentation for Conjugated Diene Polymerization
Segmented distillation columns purify solvents in conjugated diene polymerization, preventing solvent loss and catalyst deactivation from impurities.
- Prefractionation Main Column Arrangement for LAO Separation
Converting sequential distillation to prefractionation reduces plot space and capital costs by merging separation functions.
