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

Rotating Disc Contactor (RDC) Columns – Agitated Column Design

Characteristics

  • Reasonable capacity: 20-30 M3/M2-hr
  • Limited efficiency due to axial backmixing
  • Suitable for viscous materials
  • Suitable for fouling materials
  • Sensitive to emulsions due to high shear mixing
  • Reasonable turndown (40%)

Pulsed Column Characteristics

  • Reasonable capacity: 20-30 M3/M2-hr
  • Best suited for nuclear applications due to lack of seal
  • Suited for corrosive applications when constructed out of non-metals
  • Limited stages due to backmixing
  • Limited diameter/height due to pulse energy required
