Carboxylic Compound Separation/Purification TRIZ Cases
- Acrylic Acid Separation Process for Acetaldehyde By-Product Purification
Absorbent-assisted cooling and distillation separate acetaldehyde by-products from bio-based acrylic acid to improve purity, yield, and process economics.
- Acetic Acid Distillation Draw Layout for Dual Purity Streams
A two-draw distillation column creates acetic acid streams with different propionic acid levels while cutting energy use and process complexity.
