Distillation Purification/Separation TRIZ Cases
- Styrene Polymerization Inhibition via Hydroxylamine and Free Radical Blends
A hydroxylamine and stable free radical blend inhibits vinyl aromatic monomer polymerization during elevated temperature processing.
- Blending Natural Oils with Kerosene for Linear Alkylbenzene Production
Merging renewable natural oils with kerosene feedstocks maintains C10 content specifications while reducing fossil fuel dependency in alkylbenzene synthesis.
- 1,3-Butadiene Purification via Dividing Wall Column and Extractive Distillation
Dividing wall column separates C4 fractions before extractive distillation yields pure 1,3-butadiene.
- Alkylated Naphthalene Lubricant Blending for Viscosity Control
Separating alkylated naphthalene mixtures into distinct fractions allows precise viscosity and volatility control without complex parallel synthesis lines.
- Diamondoid Fuel Synthesis for High Volumetric Energy Density
Diamondoid fuels use cage structures with allyl groups to increase volumetric net heat of combustion beyond conventional jet fuel limits.
- C8 Aromatics Isolation via Segmented Fractionation Columns
Segmented fractionation columns isolate C8 aromatics from hydrocarbon streams using sidedraw withdrawal and bottom fraction processing.
- Polyalkylate Distillation Column Pressure Gradient Optimization
A polyalkylate distillation column operates with a reduced pressure gradient to separate diisopropylbenzene and triisopropylbenzene.
- Ethylene Monomer Dissolution Device for Alpha-Olefin Refrigerant Reduction
Separating monomer dissolution from the reaction zone extracts heat outside the reactor, reducing refrigerant consumption in alpha-olefin production.
- Extractive Distillation Column Overhead System for Aromatics Recovery
Recycling solvent-rich stream to lower column section reduces C8 naphthenic impurities and benzene loss in full-range feedstock processing.
- Divided-Wall Column Styrene Purification
A divided-wall column segments distillation to remove close boiling impurities from styrene while reducing energy consumption.
- Contaminated Hydrocarbon Re-refining via Flash Separator and Evaporator
Hydroprocessing removes impurities while film evaporators minimize coke formation, preventing catalyst deactivation.
- Bioisoprene Purification via Solvent Absorption and Steam Stripping
Multi-column solvent absorption and steam stripping remove water vapor, carbon dioxide, and bio-byproducts to yield high-purity isoprene for polymerization.
