Liquid-Liquid Extraction

Liquid - Liquid Extraction (LLX) Process Equipment :

LLX units with flexibility spanning use from university engineering and chemistry class and research laboratories, to use as a continuous production pilot plant. As supplied, features readily adjusted flow patterns of counter-current, co-current, cross-current, and internal recycle. Standard size LLX unit consists of a total of 10 mixer-settler (M-S) boxes. 


Pilot or Small Plant :

Unit offers a bench or pilot scale capability in LLX for your value recovery business or R&D lab. The unit is custom made in Alabama by skilled technicians and can be custom-designed to meet your needs. Designs are readily changed or refurbished as desired using available parts.
