Mixer Settler Manufacturer and Supplier in India
A Workhorse for Liquid Separation
The world of chemical processing relies on efficient and dependable tools for separating valuable components from mixtures.
Enter the Mixer Settler, a revolutionary device that simplifies and automates the separation of two immiscible liquid phases, regardless of their concentration.
Beyond Traditional Separation Techniques:
Traditionally, techniques like distillation or filtration were often used for liquid separation. However, these methods have limitations.
Distillation works best for components with significant volatility differences, while filtration might not be suitable for fine emulsions or require additional steps for solvent recovery.
The Mixer Settler offers a versatile alternative, particularly excelling in the following scenarios:
- Azeotropic Distillation: When components in a mixture have similar boiling points, forming an azeotrope, traditional distillation becomes impractical. Mixer Settlers provide a valuable solution for separating such mixtures.
- Extractive Distillation: The Mixer Settler can be integrated with distillation processes to improve product yield by introducing a selective solvent that removes unwanted components, making the desired product easier to purify in the distillation stage.
- Steam Distillation: In this process, steam is used to carry over volatile components from a non-volatile mixture. The Mixer Settler can effectively separate the condensed steam containing the desired component from the non-volatile material.
- Esterification Reactions: Many esterification reactions involve the separation of an organic ester layer from a water layer. The Mixer Settler’s efficient separation capabilities make it ideal for such applications.
These are just a few examples, and the Mixer Settler’s adaptability extends to various other processes requiring the separation and recycle of two immiscible liquid phases.
Unveiling the Inner Workings:
The core of the Mixer Settler lies in its modular design comprising a series of interconnected mixing and settling chambers. Let’s delve deeper into its key components:
- Mixing Chamber: This cylindrical chamber houses a variable-speed stirrer (often a turbine design) that vigorously mixes the two phases. This mixing is crucial for maximizing mass transfer between the phases, where the desired component partitions from one phase to the other. The stirrer’s design also incorporates a negative pressure zone at the inlet, allowing efficient liquid flow from previous stages in the process.
- Stirrer Drive Assembly: This assembly houses the variable speed motor that drives the stirrer in the mixing chamber. Adjusting the stirrer speed allows for optimization based on the specific process requirements.
- Separation Zone: After the vigorous mixing, the two phases need to separate based on their differing densities. Here’s where the separation zone takes over. The turbulent flow from the mixing chamber is calmed and converted into axial flow, directing the mixture towards the settling zone. This zone utilizes the principle of gravity, allowing the heavier and lighter phases to naturally separate due to their density difference.
- Adjustable Overflow Valve: This ingenious valve assembly plays a critical role in maintaining the separation interface between the two phases at the desired level. This level can be crucial for optimizing the extraction process. The transparent Borosilicate glass construction allows for visual monitoring of the interface, enabling operators to adjust the overflow valve accordingly.
- Separating Head: This head houses an internal overflow weir that can be manually adjusted using a handwheel. The design channels the heavier phase through a specific path, ensuring clean separation from the lighter phase.
Transparency and Efficiency: Advantages of Borosilicate Glass Construction:
The Mixer Settler’s construction material, Borosilicate glass, offers several distinct advantages:
- Visual Monitoring: The transparency of the glass allows for real-time observation of the mixing and separation processes. This visual feedback is invaluable for process optimization and troubleshooting.
- Easy Interface Adjustment: The ability to visually monitor the interface height between the phases simplifies the adjustment of the overflow valve. This ensures optimal separation efficiency even with fluctuating process conditions.
- Non-Corrosive: Borosilicate glass boasts exceptional resistance to corrosion, making it suitable for handling a wide range of chemicals. This translates to extended equipment life and reduced maintenance costs.
- Unmatched Temperature Resistance: The high temperature resistance of Borosilicate glass allows the Mixer Settler to operate effectively in processes with elevated temperatures.
A Large Interface Area for Enhanced Separation:
One of the key design features of the Mixer Settler is its horizontal Borosilicate glass vessel. This design offers a significant advantage: a large interface area for separation.
This translates to a larger surface area where the two immiscible phases can interact and separate. This enhanced surface area directly contributes to the efficiency and capacity of the separation process.
The Mixer Settler stands as a testament to innovative design in the realm of liquid separation. Its modularity, efficient mixing and settling stages, adjustable overflow valve, and the transparency of Borosilicate glass construction all come together to create a versatile and dependable tool for a wide range of chemical process applications.

Beyond the Basics: Advanced Features and Applications of the Mixer Settler
While the core functionalities of the Mixer Settler have been established, its capabilities extend beyond the fundamental separation process. Here’s a look at some advanced features and applications that further showcase its versatility:
- Multi-Stage Operation: For complex separations or situations requiring high purity, multiple mixer settler units can be cascaded in a series. In this configuration, the lighter phase from one stage becomes the heavier phase entering the next stage. This countercurrent flow significantly improves the efficiency of the extraction process, allowing for the separation of components with very similar properties.
- Heated or Cooled Operation: The Mixer Settler can be equipped with a jacket system that allows for temperature control of the process. This feature becomes crucial for applications where temperature significantly impacts the partitioning of the desired component between the phases. Heating or cooling the mixture can optimize the extraction efficiency.
- Foam Control Mechanisms: In some processes, foaming can occur during mixing, hindering separation. The Mixer Settler can be equipped with anti-foaming agents or defoaming elements within the mixing chamber to address this issue and ensure efficient phase separation.
- Interface Detection Systems: For automated and highly controlled processes, the Mixer Settler can be integrated with interface detection systems. These systems utilize sensors to monitor the interface height between the phases in real-time. This data can be used to automatically adjust the overflow valve, ensuring consistent separation efficiency.
These advanced features highlight the adaptability of the Mixer Settler to various demanding separation challenges.
Applications Beyond Chemical Processing:
While the core application of the Mixer Settler lies in the chemical process industry, its reach extends to other sectors as well:
- Hydrometallurgy: The Mixer Settler plays a vital role in the extraction and purification of valuable metals from their ores. It facilitates the selective separation of the desired metal from unwanted impurities during the leaching process.
- Nuclear Fuel Reprocessing: In the nuclear fuel cycle, the Mixer Settler is utilized for the separation and purification of fissile materials like uranium and plutonium from spent nuclear fuel. This separation is crucial for the safe and efficient reuse of nuclear fuel.
- Biotechnology: The Mixer Settler finds application in the downstream processing of bioproducts like pharmaceuticals and enzymes. It can be used for the selective extraction and purification of these valuable products from complex biological mixtures.
- Vegetable Oil Refining: The Mixer Settler can be employed in the refining process of vegetable oils to remove impurities like gums and phospholipids, improving the quality and stability of the final product.
These diverse applications showcase the versatility of the Mixer Settler as a workhorse for separation across various industries.
