Fractional Distillation Systems for Purification, Fractionation, and Solvent Recovery

The separation of volatile components (fractionation) can be achieved using Pope's state-of-the-art line of fractional distillation equipment systems, (Fractional Columns). 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 equipment is available in a multiple range of sizes from the lab scale solvent recovery through 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.

Utilizing Pope’s engineering expertise for fractional distiller equipment, 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 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.

Pope Scientific Fractional Distillation Systems are available as:

  • Batch or continuous feed applications
  • 1 to 100 gal/hr range of throughput capacities
  • 1" and larger packed column diameters, in standard flanged sections
  • 316-L stainless steel (glass & special alloys available)
  • Wide variety of column packings & internals
  • Turnkey fractional column systems, partial systems & individual components
