ASTM Distillation System D-2892

Petrodist 100 CC (ASTM D-2892)

Processor controlled turnkey crude oil distillation system for fully automatic operation without user intervention exactly conforming to ASTM D-2892 (TBP), latest revision.

The system is computer controlled and designed for fully automatic operation throughout the different distillation runs at different pressure levels which includes:

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

These different distillation runs are performed automatically without any intervention of the operator. The system automatically manages the changes of all involved pressure changes from atmospheric to the different vacuum conditions. The duration of the intermediate cooling procedure in between the different runs is minimized by an intensive cooling of the flask charge.

The system measures the distillation rate with an online volume measuring system of each fraction before each cut is being discharged into an automatic fraction collector with 20 receivers. The fraction collector is equipped with an inbuilt electronic balance to measure the weight of each fraction. By replacing filled receivers even during operation, the system can handle up to 80 cuts for the distillation of one sample. The receiver change is performed according to pre-selected cut temperatures or when a receiver is filled up to continue the cut sampling in the next receiver (to avoid overfilling of the receiver).

After the distillation, the operator needs to weigh the gas trap as well as the flask residue by the external balance (part of delivery), the weights are automatically taken by the system and as a result the final data evaluation and TBP-curves in weight-% and volume-% are printed out and can be stored.

A data station for overriding parameter input as well as for display of all operation parameters, distillation results and TBP-curve, as well as an external balance is included.

The system is modularly constructed and provides the possibility to allow several options like online density measurement, water removal (prior to the start of the distillation), stainless steel flasks, gas detector, hydrogen sulfide-alarm as well as a complete sheathing of the system.

The system requires for operation water, nitrogen, compressed air and electricity to be supplied by lab infrastructure.

Key features include:

  • Tick Computer controlled fully automatic process without any interruption
  • Tick PILODIST IP65 control panel with 15,6” touch screen mounted at the side of framework or alternatively stand alone as table top unit
  • Tick Continuous monitoring of distillation process and data storage
  • Tick Boil-up rate controlled by differential temperature, differential pressure, power regulation and distillate volume
  • Tick All distillation parameters can exactly and reproducibly be selected
  • Tick Fraction and receiver changes are performed acc. to preselected cut temp.
  • Tick fully automatic product discharge into sealed final receivers without any influence on the distillation process
  • Tick Automatic debutanization process
  • Tick Adiabatic operation due to column heating jacket
  • Tick Reduced cooling periods between runs by using a quench cooler and nitrogen
  • Tick Cooling down process after each run automatically
  • Tick Precise vacuum control
  • Tick Electrical lifting platform for flask
  • Tick Evaluation of the “final data” and printout of TBP-curve in Microsoft Excel
  • Tick Several safety and alarm options available
  • Tick Automatic online volume and automatic weight measuring
  • Tick All distillation data (results) will be stored even in case of an alarm, followed by automatic shut down
  • Tick Optional automatic online density measurement
  • Tick Optional water removal (dehydration)
  • Tick Various further options available to customize the system
