Crude Oil Distillation, Fully Automatic, Potstill (D5236)

Turn key processor controlled crude oil distillation system for fully automatic
operation according to ASTM D-5236 (Standard Test Method for Distillation of Heavy
Hydrocarbon Mixtures, Vacuum Potstill Method).

The system is designed for unattended operation (during the distillation), the safety
devices are designed accordingly.
Data station for data input as well as for display and print out of all operation
parameters, distillation results and distillation curve.
The distillation ensues automatically from the start to the pre-selected or detected
end point. The distillate volume is automatically recorded by means of an integrated
volume follower system. The volume is measured separately on every individual
receiver. The unit does not contain any intermediate receiver i.e.: to avoid reblend of
the distillate. The volume calculation is expressed as percentage corresponding to
the weight and the volume of the flask charge or total recovery. The distillation curve
is printed out in weight and volume percent.

The fraction changes are carried out automatically, alternatively according to a pre-
selected boiling temperature or distillate volume or when the receivers are filled up.
The vacuum-tight fraction collector contains 12 receivers with a capacity related to
the flask size.

The boil up rate is controlled according to a pre-selected distillation rate in ml/min. An
accurate vacuum control guarantees the required stability of the distillation pressure.
All necessary accessories will be supplied together with the system.

The installation requires water, nitrogen, compressed air and electricity.
