These multistage centrifugal extractors, also known as centrifugal contactors, or liquid / liquid extraction centrifuges offer the following advantages and benefits:
- Counter-current continuous extraction for maximum efficiency
- Up to 7 extraction stages in a single rotor
- Single rotor minimizes spare parts and maintenance costs
- Very low residence time
- Rapid operational equilibrium facilitating batch-wise or continuous extractions
- Low hold-up relative to throughput
- Chemical and hydraulic equilibrium achieved rapidly
- Compact installation
- Efficient phase separation
- Vapor-tight construction with the possibility of inert gas blanketing
- Interphase position is independent of the total and relative flowrates of the two phases
- No mechanical seals required
- Multiple inlets for processing flexibility
- Unattended operation
- High extraction efficiency
- Discrete stage-wise operation
- Laboratory, pilot, and industrial scale machines available
- Cart or skid mounted systems for easy portability
- Rental equipment available
