Every distillation pilot test involves a setup customized for the application at
hand. Varying configurations are available for flashing, steam
stripping, vacuum, azeotropic, multi-component and non-ideal
processes. Column internals can be either trays or packing. Flanged
column sections are used to provide maximum flexibility for
arrangement of internals. Both stainless steel and glass sections
can be used. Provisions can be made for multiple feed point
locations, as well as vapor or liquid sidedraw.
Reboilers
can be kettle, thermosiphon, forced circulation or falling film,
heated by steam, hot oils, or electricity. Alternatively, direct
steam addition can be utilized.
Operating pressures from 30 PSIG to 1 mmHg absolute are possible.
Heat loss is minimized by means of heat tracing and insulation.
The pilot column is run over a range of operating conditions to
measure separation performance and help determine optimum
conditions. Other observations, such as operating stability,
foaming, fouling, or thermal degradation, are also made and
recorded. This type of data and information is extremely important
for process scale-up.
