Distillation Purification/Separation TRIZ Cases
- Olefin Oligomerization Process with Segmented Reactors and Thermal Integration
Segmented oligomerization stages coupled with thermal integration reduce energy consumption while maintaining high olefin conversion rates.
- Olefin Oligomerization Distillation with Bottoms Recycle
Recycling intermediate bottoms to the final column concentrates starting olefins, reducing investment costs from excessive separation stages.
- Prefractionation Column for Heavy Aromatic Removal
A prefractionation column separates spent regenerant streams into overhead and bottoms fractions using low temperature fluid vaporization.
- Partitioned Extractive Distillation Column for Hydrocarbon Separation
A fully partitioned column performs consecutive extractive distillations to separate aromatic, naphthene, and paraffin hydrocarbon families.
- Styrene Purification via Cascaded Distillation Heat Integration
Elevated pressure operation and cascaded column design separate ethylbenzene from styrene while cutting energy consumption by up to 100%.
- Olefin Conversion via Distillation and Dynamic Feed Control
Dynamic distillation removes inhibitors from olefin feeds, resolving the contradiction between high productivity and reliable selectivity.
- Aromatic Transalkylation Process Hydrogen Purity and Energy Efficiency
Hot separator flash drums remove light hydrocarbons from aromatic transalkylation effluent, maintaining hydrogen purity without purge gas loss.
