The centrifugal extractor mixes two immiscible liquids, a solvent and a liquid mixture, to extract a component from the mixture.


The extraction process involves:


1. Mixing an extraction solvent with the mixture for mass transfer


2. Separation of the raffinate and extract phase


3. Recovery of the desired component from the raffinate, usually by distillation


Process Description


The CTL Liquid/Liquid extractor/separator features a mixing and mass transfer process between two phases concurrently in the equipment.


1. Mixing and Mass Transfer Process: Two phases of different densities are fed into the vessel and mixed for an efficient solute transfer from the mixture to the solute.


2. Separation Process: The two phases are accelerated via the rotor and separated based on their differing densities. The denser phase is brought closer to the drum walls and exits through the top weir, while the lighter phase exits through the central weir.




Small space requirements with no electrical actuators required


Lower retention time and suitable for a wider range of flow ratios as compared to conventional extraction equipment


Weir plates and rotation frequency can be adjusted for liquids of different densities and viscosities


The single/multi stage equipment in either countercurrent or crossflow arrangement establishes equilibrium quickly


Fully automatic equipment for uninterrupted continuous operation


Small equipment requires minimal solvent/extract consumption


The airtight equipment is suitable for explosive, toxic, hazardous and volatile fluids


Meets environmental and GMP requirements


Various optional add-ons such as a Clean-In-Place (CIP) mechanism, inverters or an anti-emulsification setup





Technical Innovations


By changing the electrical motor for a belt drive, the system will achieve explosion prevention requirements.


Changing the cantilever support into a multi legged structure provides increased stability.


A specially designed drum provides an improved extraction & separation efficiency, and greatly reduces operation costs.


A CIP mechanism eliminates problems caused by solid sediments.


Anti-emulsifying structure to suit a larger range of applications.


Multi-stage setup solves process issues such as gas lock.
