Liquid-Liquid Extraction Equipment Manufacturer and Supplier in India
Liquid-liquid extraction, also known as solvent extraction, offers a powerful technique for separating desired components from a liquid mixture.
This process relies on the selective solubility of target compounds in a chosen immiscible solvent. Here, we delve into the world of liquid-liquid extraction equipment, exploring its functionalities and applications.
The Science Behind Separation
Imagine a mixture containing a valuable component you wish to isolate. Liquid-liquid extraction equipment facilitates this by introducing a carefully selected solvent that preferentially dissolves your target molecule. This solvent doesn’t readily mix with the original liquid mixture, forming two distinct phases:
- The extract: This phase contains your desired component dissolved in the chosen solvent.
- The raffinate: This phase comprises the original liquid mixture minus the extracted component.
By carefully controlling the contact between these two phases and exploiting differences in density, separation is achieved.
Equipment Breakdown: A Closer Look
Our liquid-liquid extraction equipment operates in a semi-batch mode, providing an efficient and versatile solution for your separation needs. Let’s dissect the key components involved:
- Extraction Vessel: This vessel serves as the heart of the process, holding the liquid mixture from which you want to extract your target component. It’s available in 10, 20, and 50-liter capacities to suit your specific needs.
- Reboiler Vessel: This vessel plays a crucial role in solvent recovery. The solvent, after fulfilling its extraction duty, is collected here and boiled to generate vapors.
- Overhead Condenser: As the solvent vapors rise from the reboiler, they encounter the condenser. This component cools the vapors, converting them back into liquid form.
- Reflux Divider: The condensed solvent exits the condenser and flows into the reflux divider. This divider regulates the flow of the condensed solvent, allowing a portion to return to the top of the extraction vessel (reflux) and the remaining portion to be directed for further extraction.
- Piping Network: This intricate network of pipes ensures efficient solvent flow throughout the system. Strategically placed valves enable control over the solvent’s entry point into the extraction vessel, either at the top or bottom, depending on the density differences between the solvent and the liquid mixture.
The Extraction Process: A Step-by-Step Guide
- Charge the Extraction Vessel: The liquid mixture containing your target component is introduced into the extraction vessel.
- Solvent Reheating: The solvent, stored in a separate container, is transferred to the reboiler vessel and heated to its boiling point.
- Solvent Condensation: The generated solvent vapors travel upwards and encounter the overhead condenser. Here, they cool down and condense back into liquid form.
- Solvent Flow Control: The condensed solvent enters the reflux divider. A portion of this solvent, designated as reflux, flows back to the top of the extraction vessel. The remaining solvent is directed for further extraction.
- Solvent-Mixture Contact: The refluxed solvent and the solvent specifically directed for extraction come into contact with the liquid mixture in the extraction vessel. During this crucial stage, the chosen solvent selectively dissolves your target component, forming the extract.
- Extraction Cycle: The mixture of solvent and extracted component, along with the raffinate (the remaining liquid mixture devoid of the target component), gravitate back down to the reboiler vessel due to density differences. This cycle of solvent boiling, condensation, extraction, and settling continues until the desired level of extraction is achieved.
- Product Recovery: Once extraction is complete, the contents of the extraction vessel are drained. Back in the reboiler vessel, the solvent is evaporated, leaving behind the isolated extract. Finally, both the extract (containing your target component) and the raffinate (the remaining depleted liquid mixture) can be collected from their respective vessels.
