Pilodist

Compact design with control system and safety items for unattended operation. No operator intervention and no intermediate stops are required.

The distillation ensues automatically from the gas cut (IBP) to the pre-selected end point without any interruptions and any interventions. The yield calculation refers to the weight of the flask charge. The weights of the fractions are detected by means of a build in electronic balance prior to the discharge from the system into the fraction collector. The system can alternatively be equipped with a volume follower for volume detection.

A data station for overriding parameter input as well as for display and print-out 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 water removal (prior to the start of the distillation), stainless steel flasks, gas detector, hydrogen sulfide-alarm and trap as well as a complete sheating of the system. The TBP-curve will then be printed out in weight and volume percentage.

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.

Special advantages:

• Processor controlled Crude oil distillation system according to ASTM D-1160.
• Computer as parameter input and display unit as well as calculation of the distillation data and printing of the distillation curve.
• Menu control guarantees uncomplicated operation.
• Flexible parameter selection makes using of the system for continuous problem definitions possible.
• Perfected safety system.
• Distillation reports and curves can ever be re-called.
• Calculation of charge according to receiver temperature and charge density.
• Detailed distillation data by self-calibrated accurate volume measuring system.
• Minimum installation effort as the system is delivered ready for operation.

The distillation is automatic, from the initial boiling point to the pre-selected end boiling point or detected break-off. The criteria for break-off are:

• The pre-selected final AET (atmospheric equivalent temperature) is reached.
• The maximum bath temperature is reached.
• The maximum flask temperature is reached.
• The pre-selected distillate volume is reached.
• The flask insert cracks.
• The distillate pressure drops.
• Product lack in the flask.

The distillation volume is measured automatically in a tempered receiver. The yield is calculated in percentage to the charge quantity. Distillation report, final data and distillation curve are printed out.
