Crude Oil Distillation System

by B/R Instrument

This distillation system is designed for the fully automatic distillation of crude oil and petroleum products. Crude oil distillation can be complex and time consuming. Our crude oil distillation system includes everything needed to perform the ASTM methods, D2892 and D5236, for distilling crude oil. The system’s automation minimizes the operator time needed to perform the test. The equipment design makes the test straightforward and easier to perform.

Distillation Column Configuration

The crude oil distillation system can come in a wide variety of configurations with single or multipledistillation columns.

D2892 Crude Oil Distillation

The packed column configuration is used to distill the crude oil up to a maximum 450°C atmospheric equivalent vapor temperature. It is some times called true boiling point distillation or D2892. The distillation column has 15 theoretical plates and complies fully with ASTM D2892. Pot sizes of 2 to 100 liters are available.

A variety of column packing types are available including Propak, Helipak, and structured packing. Other packing types are also available.

The vacuum pot still configuration is typically used to distill the residual material from the D2892 distillation out to atmospheric equivalent vapor temperatures up to 565°C or higher. The vacuum pot still complies fully with ASTM D5236. Pot sizes of 1 to 22 liters are available.

A two crude oil distillation column configuration is also available. Usually, one distillation column is the D2892 packed column (true boiling point) and the other is the D5236 vacuum pot still column. Only one distillation column is operated at any time. Both distillation columns share the same microprocessor, fraction collector, vacuum control system, and recirculating bath.

Spinning band distillation columns are available in addition to traditional packed columns and vacuum pot stills. The spinning band distillation columns can accommodate pot sizes from 10 ml to 12 liters.


The Automaxx 9100 automatically produces fractions and a true boiling point curve. The crude oil distillation system is operated by a Pentium processor and a Windows operating system. All distillation functions are automated to make the crude oil distillation process easy and efficient from beginning to end. Up to 1,000 crude oil distillation programs can be stored.

Fraction Collection

The fraction collector can automatically collect crude oil fractions based on temperature cut points at atmospheric pressure or under vacuum. Receivers come in a variety of sizes. Up to 32 fractions can be collected for each pressure level.

D5236 Crude Oil Distillation
Vacuum System

Distillation of crude oil above 200 °C must be performed at reduced pressures. The vacuum system includes a 2-stage mechanical vacuum pump, cold trap, pressure sensor and proportional control valve. The operator can input a vacuum set point from 100 mmHg to 0.1 mmHg and the vacuum system will automatically control vacuum to the set point level.

Spare Parts

A spare parts kit is available which includes the parts necessary to keep your crude oil distillation system operating. B/R Instrument stocks all parts for fast deliveries.
