Liquid-Liquid Extraction is a separation process in which a feed stream containing dissolved components is contacted with an immiscible solvent which forms a second liquid phase and selectively extracts the dissolved components from the feed. It is primarily used for services where distillation is not practical, like close boiling point or heat sensitive materials.
Packed columns in liquid-liquid extraction are used in certain extraction services, such as alcohol washing and contaminant removal from light hydrocarbon. Packed columns are flexible and can handle wide range of feeds and extract to feed ratio. Packed columns are equipped with internals like Disperser Plate/Disperser cum Support Plate, Feed pipes for Dispersed and Continuous Phase. Packing promotes, contacting of two phases, as they have to follow tortuous path through packed bed. It brings both the phases in close contact, maintaining dispersion and preventing short-circuiting.
The following types are available:
- Light Phase Disperser Support Plate
- Heavy Phase Disperser Support Plate
