Purification, Fractionation, and Solvent Recovery
The ideal separation of volatile components (fractionation) can be achieved using Pope's state of the art range of fractional distillation systems. Fractional distillation is particularly suitable for critical applications that require separation of complex mixtures such as fine chemicals, pharmaceuticals, foods, flavors, cosmetics, extracts, etc. – anywhere where a finer level of purity is needed or when component’s boiling points are close.
Fractional distillation eqiupment is available in a multiple range of sizes from the lab scale solvent recovery to processing scale.
Pope specializes in mid-size fractionation columns. These precision designed fractionations units fill the gap between small laboratory bench scale fractional distillation units and large process systems for critical applications. The 1 - 100 gal/hr throughput capacity is ideal for pilot plants and for applications requiring small runs. These systems incorporate exacting design and fabrication with meticulous finishing to rigorous standards.
Utilizing Pope’s engineering expertise, together with Pope's hands-on toll distillation experience, we provide assistance with design, (including evaluation for theoretical plates, plus energy required for desired separation), and can determine the necessary components for the best configuration for your needs. The ideal fractional distillation unit is then manufactured, tested and delivered.
Installation and in plant training are more features available to complete the complex distillation processing solution.
Batch Mode Stills are used when relatively small quantities of liquid are to be processed or when an extremely high level of purity is required.
