Distillation Regulation/Control TRIZ Cases
- Adjustable Gas Phase Distribution Control for Dividing Wall Columns
An electromagnetic mechanism adjusts inlet sizes to resolve inaccurate gas phase distribution and narrow adjustment ranges in dividing wall columns.
- Maple Syrup Evaporator Flow Reversal to Prevent Scale
Periodic flow reversal disrupts mineral precipitation patterns, reducing scale formation on pan walls while maintaining evaporation productivity.
- Multi-Stage Stripper System with Mechanical Vapor Recompression
A multi-stage stripper system integrates a condense-evaporator and mechanical vapor recompression module to recover heat from overhead vapor.
- Acetic Acid Distillation Column Pressure Control
A pressure control unit stabilizes distillation column pressure while scrubbing removes acetaldehyde from off-gases to prevent accumulation.
- Cross-Flow Mass Transfer Column Liquid Distributor Design
Segmented nozzles extend stable operation from 5% to 100% reflux flow rates, preventing gas bypass and enhancing fractionation efficiency.
- Dividing Wall Column for Crude 1,3-Butadiene Separation
A dividing wall column separates crude 1,3-butadiene from a C4 cut using extractive distillation with a selective solvent.
