Choosing
the Right Still
In
the consideration of high volume distillation as a chemical process
certain factors control equipment sizing and production capacity.
The expected goal or objective of the distillation should be well
defined in advance.
Also,
such previous data as composition of the feed material, decomposition
temperatures, molecular weight, etc. should be available.
Production
capacity of high-volume distillation equipment is influenced by
many factors:
- percentage
of low-boiling volatiles as well as dissolved air, moisture,
or other gasses in the feed material
- Viscosity
of the feed material.
- Temperature
differential between feed temperature and evaporator surface
temperature.
- Operating
pressure.

Typical Maximum throughput is shown but can vary dependent
on the process performed and the preconditioning of the
feed material.

Water requirements can vary dependant on process with use
of refrigeration units |
