PETRODIST 200 HV is a processor controlled crude oil distillation system for automatic operation following ASTM D-5236 for distillation up to a final temperature of 600° C AET.
The crude oil is charged into a 33 L stainless steel flask for charge of 10-22 L of crude oil and heated by an electrical heating bath. The heating bath has 3 horizontal heating zones which can be activated or de-activated according to the filling level of the flask. All rising vapors are passing through a DN 100 stainless steel column and are condensed in an integrated vertical condenser. An additional high performance condenser made of borosilicate glass which is located on top of the column construction is required to condensate all remaining light boiling components.
The distillation is performed in several pressure steps (atmospheric and vacuum) until a final atmospheric equivalent temperature (AET) of 600°C. During distillation residue samples can be automatically be discharged into another fraction collector for the residue via a vacuum tight gear pump. Once the final temperature is reached and distillation is finished the hot residue in the flask can be discharged as well from the bottom of the flask.
The PC-based PILODIST- process control system includes control of heating and vacuum as well as the display and storage of all important process values:
- Temperature of heating bath (PT 100)
- Temperature of product in flask (PT 100)
- Temperature of vapor (PT 100)
- Pressure of distillation (0-100Torr)
