VSF^®X mixer-settler

Our renowned SX knowledge is integrated in the innovative VSF® X mixer-settlers. This environmentally friendly product is available with fast-track delivery, predefined costs, state-of-the-art documentation and implementation, efficient logistics, and fast installation.

VSF^® X DOP unit

DOP (Dispersion Overflow Pump) Unit provides optimized droplet size distribution and excellent dispersion to give a very low entrainment values and fast and complete extraction reactions. It also offers highest volumetric throughputs.

VSF^® X Spirok unit

Spirok mixer unit maintain the dispersion to give enough residence time for the ion transfer reactions. Double helical impeller creates a gentle and uniform mixing with very low energy input. Vertical mixing pattern keeps the dispersion together and no small droplets are created.

VSF^® X settler

VSF (Vertical Smooth Flow) X modular deep settler combined with DDG X separation fences provides effective separation enabling efficient footprint and enhanced coalescence of small droplets minimizing entrainments.

VSF® X organic and crud treatment unit

The organic and crud treatment unit is a ready-made auxiliary treatment unit for the VSF^®X plant. Designed to treat both formed crud and oxidated organic and return separated liquids back to the process. It enables efficient and continuous VSF^®X solvent extraction process and is easily integrated to VSF^®X plant.
