PETRODIST 100 S semi-automatic, ASTM 2892

Crude oil distillation system for semi-automatic operation exactly according to ASTM D-2892 (TBP).

The system is designed for automatic operation within each of the following distillation runs:

  • Debutanization
  • 1. run at athmospheric pressure
  • 2. run at vacuum 100 Torr
  • 3. run at vacuum 10 Torr
  • 4. run at vacuum 2 Torr

After each run, the system stops automatically and the flask temperature has to be cooled down prior to the next distillation run. The operator has to enter the parameters for the next run to restart operation. The system contains a vacuum tight automatic fraction collector with 9 receivers for each run, which have to be replaced after each distillation run. The receiver change is performed according to pre-selected boiling temperature or when a receiver is filled up.

Key features:

  • microprocessor controlled, based on multifunctional serial bus system
  • PC with windows based operation and evaluation software
  • continuous monitoring of distillation process
  • continuous report and data storage
  • flask heater control by differential temperature, differential pressure, power regulation or preselected fixed temperature
  • all distillation parameters can be exactly and reproducibly selected
  • automatic receiver change by preselected cut temperatures
  • debutanization process manually
  • cooling down process manually after each run
  • precise vacuum control


  • stainless steel flask
  • immersion cooler for vacuum cold traps and gas trap
