Fractional Distillation TRIZ Cases

Anti-jump plates segment a multiple downcomer tray to prevent inhomogeneous liquid flow, ensuring consistent gas-liquid ratios and improved tray efficiency.

Support-area-aeration apertures and a tilting canopy cover redirect vapor flow over tray supports, increasing capacity by 5-25% while reducing pressure drop.

A natural circulation reboiler heats waste liquid through heat exchanger tubes to drive continuous vaporization.

Reduced pressure distillation overcomes azeotrope formation with methanol, water, and allyl alcohol to isolate high-purity acetonitrile.

Separate deflector members mounted via vertical legs prevent cracking in brittle materials while increasing tray capacity by up to 18 percent.

Segmented distillation columns purify solvents in conjugated diene polymerization, preventing solvent loss and catalyst deactivation from impurities.

Converting sequential distillation to prefractionation reduces plot space and capital costs by merging separation functions.

Segmented side draws in one column resolve azeotrope issues, reducing unit count while maintaining purity.

Screw-fastened partition plates prevent gas leakage and maintain sidestream purity in thermal separation columns.

Angled circumferential vanes on a valve tray redirect ascending vapor downward, improving vapor-liquid contact efficiency and reducing backflow.

Alkylphenol complexes with boron and phosphorus impurities in crude chlorosilanes to enable high-purity separation through simple distillation.

Openings in the support structure allow horizontal mass transfer, preventing cascading effects and maintaining separation efficiency in large-diameter columns.

Double-walled cylindrical partitions isolate temperature gradients across the column, preventing thermal stress and mechanical skewing.

Evaporation and inert gas stripping remove cyclic alkylene carbonates from polycarbonate polyols, reducing residual impurities below 100 ppm.

A distillation column tray assembly features an enlarged, funnel-shaped upper downcomer region to increase hydraulic capacity and liquid flow speed.

Segmented distillation reduces water content in methanol reflux streams, lowering energy consumption and extending catalyst life.

Trapezoidal-wave corrugation creates alternating relief zones that reduce sensitivity to column levelness errors while expanding the operating range.

A dividing wall column separates nitroalkanes from hydrocarbon feedstocks to resolve high energy consumption in conventional distillation.

A distillation column separates polybutene from halogenated and non-polar hydrocarbon solvents using controlled viscosity ranges.

An asymmetric valve design reduces weep and pressure drop while maintaining manufacturing ease.
