VDA9000
Automatic Vacuum Distillation System
The Koehler VDA9000 Automatic Vacuum Distillation System performs automated
reduced pressure distillations for the fractionation and collection of crude
petroleum products and/or high boiling components according to ASTM D2892 and
D5236. The system is fully computer automated, featuring an automatic
fraction collector equipped with twelve (12) receivers and a built-in
internal balance, a distillate volume optical sensor system used for the
simultaneous determination of the fractional weight and collected volume for
direct distillation rate control, and a separate volume follower system for
discharging the fractions into the final receivers with determination of the
fraction volume. Under the TBP mode, the following steps are automatically
performed: debutanization, atmospheric distillation, and vacuum distillations
at 100, 10, and 2 mm Hg. Under the Potstill mode, two distillations are
automatically performed at predesignated pressures programmed by the operator
between 0.1 and 10 mm Hg. The final test data including the TBP and/or the
Potstill distillation curves in weight % and volume % are printed out at the
conclusion of the test.
