Small Scale
Crude Oil Distillation
36-100 Spinning band distillation system
25ml to 1 liter range.
The need for
information about the composition of crude oil has become an
increasingly important topic among refiners, oil producers and
researchers. These professionals want an easy, automatic distillation
system that can produce distilled fractions quickly. Often the
available volume to be distilled is very small, between 15ml
and 1000 ml.
Traditional crude oil distillation systems have problems with small samples.
A large amount of material can be held up in the distillation column packing.
This skews the results and makes the distillation process difficult or impossible.
Spinning band distillation has two very unique characteristics, low hold-up
and low pressure drop. Low hold-up means that very little sample is left in
the column at the end of the distillation. For spinning band distillation columns
the hold-up is usually much less than 1 ml. This is very important when dealing
with very small samples. Low pressure drop means that there is very little
back pressure created by the spinning band. This permits the spinning band
distillation column to handle everything from very light materials to viscous,
high boiling materials.
 The
low pressure drop and low hold-up of the spinning band distillation
column makes it ideal for distillation of crude oil from the initial
boiling point to as high as 565 °C (final boiling point depends
on crude oil type and sample handling). Traditionally, two distillation
columns are needed, one from initial boiling point up to 400 °C
and a second distillation column is needed from 400 to 565 °C.
A major advantage of spinning band distillation is that this can all
be done with one distillation column. This greatly simplifies the whole
distillation process by eliminating the change over from one distillation
system to another. This is particularly important with very small samples
since material is lost in the changeover process.
Additionally, the spinning band provides for a distillation curve with no discontinuities.
Using the traditional method, a discontinuity occurs in the distillation curve
when changing over from a packed column to a vacuum pot still. This does not
occur with the spinning band since one distillation column is used from beginning
to end.
Lastly, the spinning band has a great separating efficiency. It has a maximum
of 80 theoretical plates at atmospheric pressure. As a result, the fractions
are very sharp, having much less cross contamination than with a traditional
distillation system.

Automation
and Accessories:
All our distillation equipment is available in fully automatic or manually
operated models. Manually operated systems are inexpensive and simple to operate.
Automatic models are microprocessor controlled. All the distillation functions
are fully automated to make the distillation process easy and efficient from
beginning to end.
M690
Microprocessor Controller
 The
microprocessor minimizes the amount of operator time required
for each crude oil distillation. Call up your stored program
from one of 19 available memory locations and let the microprocessor
perform the crude oil distillation. Each program can store up
to eight distillation fractions. Each fraction has programmable
open and close temperature cut points, heat rates, reflux ratio
and equilibration times. Programmable shut down at the end of
the distillation run. The microprocessor allows easy editing
of each of the parameters while the distillation is in progress.
Automatic and Manually Operated Fraction
Collectors
Four and eight
place fraction collectors are available to direct distilled material
to the desired receiver. Automated versions allow distilled fractions
to be collected unattended. Manually operated versions are also
available.
