Extraction Column Types: Agitated and Static Columns for Liquid-Liquid Extraction
As part of our liquid-liquid extraction equipment, Koch Modular has a wide range of extractors to choose from, both static and agitated columns. In addition to Koch Modular’s signature KARRⓇ Columns and SCHEIBELⓇ Columns, we also provide rotating disc contactors (RDC), pulsed columns, and special designs for those in need of an agitated column design, as well as sieve trays, random packing, and structured packing (SMVP) static columns.
Agitated Columns
KARRⓇ Column – Liquid Liquid Extraction Equipment
Characteristics
- Highest capacity: 30-60 M3/M2-hr
- Good efficiency
- Good turndown capability (25%)
- Uniform shear mixing
- Best suited for systems that emulsify
SCHEIBELⓇ Column – Liquid Liquid Extraction Equipment
Characteristics
- Reasonable capacity: 15-25 M3/M2-hr
- High efficiency due to internal baffling
- Good turndown capability (25%)
- Best suited when many stages are required
- Not recommended for highly fouling systems or systems that tend to emulsify
Static Columns
Packed – Random
- High capacity: 40-80 M3/M2-hr
- Poor efficiency due to backmixing and wetting
- Limited turndown flexibility
- Affected by changes in wetting characteristics
- Limited as to which phase can be dispersed
