Countercurrent Supercritical Fluid Fractionation System

Model: SFE-CF

The FLOSN SFE-CF is designed for countercurrent fractionation of suitable liquid feeds using supercritical CO₂. The proposed platform brings a descending liquid phase into contact with an ascending CO₂-rich phase inside a temperature-zoned packed column. Selected components transfer between the phases according to their partition behavior, producing an extract stream and a raffinate stream. Independent feed delivery, CO₂ metering and controlled product withdrawal support the development of continuous fractionation methods for compatible oils, fragrance intermediates and other low-volatility liquid mixtures.

FLOSN / PRODUCT FEATURES

Product Features

8 FEATURES

01Continuous Liquid-Feed Operation

Independent metering is proposed for liquid feed and CO₂ once a stable operating window is established.

02Temperature-Zoned Contact Column

Three controlled thermal zones allow axial temperature profiles to be investigated.

03Replaceable Packing

An accessible column assembly allows packing and distributors to be selected for the intended separation.

04Selectable Feed Locations

Multiple engineered ports support comparison of upper and intermediate feed positions.

05Separate Extract and Raffinate Paths

Independent outlet handling supports product sampling and material-balance measurements.

06Hydraulic Monitoring

Column differential pressure and flow trends are proposed to help identify changes in loading or flooding behavior.

07Optional Reflux and CO₂ Recovery

Dedicated modules can be added after separation trials define the required recycle configuration.

08Pilot-Scale Method Development

The platform is intended to evaluate partitioning, residence behavior and collection strategy before scale-up.
