Vacuum Distillation Separation TRIZ Cases

Sulfur pre-treatment removes copper-driven solids in lead-tin vacuum distillation, maintaining melt fluidity and continuous high-purity separation.

Pre-cooling and dross separation keep molten solder fluid during vacuum distillation, preventing clogging while recovering high-purity lead.

Removing water before distillation prevents azeotrope formation and improves acetonitrile recovery from low-purity waste streams.

Amine-alcohol solvent extracts organic acids from aqueous solutions, followed by water back-extraction to recover high-concentration product.

A closed system uses a desiccant to create a pressure gradient for ambient solvent evaporation.

Vacuum heating removes residual solvents from the extract, achieving zero contamination in shatter or budder products.

Segmenting atmospheric pressure residual oil into satellite sub-reactors and a main kettle reduces coking risk while improving light oil extraction rates.

Reclaimed terphenyl thermal fluids maintain pumpability at room temperature while resisting degradation, reducing waste from tar formation.

Low-concentration sulfuric acid neutralizes alkali catalysts while limiting 2-methyl-2-pentenal formation from acid-catalyzed condensation.

An independent impeller distributes molten polymer on a duct wall to extract volatile compounds without damaging mechanical properties.

A vacuum centrifuge uses a single drive motor and magnetic coupling to rotate the rotor head and sample container independently.

Vulcanizing agent mixes with crushed crude selenium slag to form mercury sulfide before vacuum distillation separates the purified metal.
