Description

Instrumentation and control of distillation columns have changed considerably in the recent years, prompted by the advances of computer-linked systems which are generally supported by powerful software packages which allow the operators to handle operating data.

Armfield has acknowledged these recent changes and has developed two state-of-the-art laboratory-based distillation columns which enable safe hands-on practical training for student engineers and plant operators as well as empowering research in different fields to be conducted.

Armfield have designed two distillation column options:

UOP3BM: Batch Distillation Column (Manual) A Batch-only operated version, manually controlled, which permits a comprehensive study of the basic principles involved in the distillation process.

UOP3CC: UOP3CC – Continuous Distillation Column (Computer Controlled) A Continuous or Batch operated version, computer controlled, which enables a full range of demonstrations from the introductory stages of a process engineering course through to the more complex demonstrations of modern control strategies

Each option comes with two different distillation columns supplied:

A packed bed distillation column

A sieve plate distillation column, including eight sample and feed ports across the column

Armfield UOP3CC and UOP3BM are the only units on the market with this sampling capability. The column is unique because it can use flammable solvents. In addition, sample ports can be utilised as additional feed positions on each sieve plate. Correct at time of product release.

The unit is a self-contained and fully instrumented distillation facility, suitable for practical laboratory work relevant to the teaching of unit operations.

The equipment employs galvanically isolated intrinsically safe circuits and flameproof devices as appropriate to enable safe distillation of standard test mixtures such as methylcyclohexane-toluene, methyl alcohol-water etc.

The equipment consists of two interconnected units: a floor standing process unit and a bench-mounted control console.

The system includes two distillation columns supplied as standard:

A 50mm diameter plate distillation column containing eight sieve plates and downcomers. Every plate includes a temperature sensor positioned to measure accurately the temperature of the liquid on each plate. The sheaths of each plate temperature sensor are not more than 1.5mm diameter to ensure rapid dynamic response.

A 50mm packed column supplied as a separate item but readily interchangeable with the plate column by the user, for comparative studies of the two types of distillation column.
