General Description

The Advanced Computer Controlled Deodorizing Unit, "AEDC/A", designed by EDIBON is a unit that allows the study and research of the continuous deodorization operation capable of performing a vacuum and high temperature distillation with steam.

In the deodorization process, natural fatty acids (GFA) are removed from different types of vegetable oils, allowing the study of the main factors that influence the process.

The main element is the column that has structured filling and trays, to carry out the separation of fatty acids (stripping), also to wash the gases generated (scrubbing) has another structured filling fraction. After each operation, two demisters separate the liquids in the form of small particles contained in vapors and gases by coalescence.

The feed to the column is distributed evenly through collectors. To improve the exchange of material, superheated steam is injected into the column. The extracted fatty acids are recirculated through the head of the column to avoid cooling and therefore solidification and the possibility of clogging the ducts. Thermal oil circulates through the column’s coil, providing the necessary energy to keep the vegetable oil warm for the necessary residence time until the deodorization stage is completed. Along the column there are sensors that record the temperature and pressure at the different heights of the column.

Heat exchangers are used to provide the necessary thermal jump to the typical deodorisation temperature of the specific vegetable oil.

The feed tank allows the oil to be deodorised to be stored as well as being de-aerated and heated to suit the process conditions.

The refined oil tank stores the oil that has been deodorised for subsequent analysis.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.

MORE PRACTICAL EXERCISES TO BE DONE WITH THE UNIT

  1. Sensor calibration.
  2. Study of the impact of the type of packing in the fatty acid removal process.

Other possibilities to be done with this Unit:

  1. Many students view results simultaneously. To view all results in real time in the classroom by means of a projector or an electronic whiteboard.
  2. Open Control, Multicontrol and Real Time Control. This unit allows intrinsically and/or extrinsically to change the span, gains, proportional, integral, derivative parameters, etc, in real time.
  3. The Computer Control System with SCADA and PID Control allow a real industrial simulation.
  4. This unit is totally safe as uses mechanical, electrical/electronic, and software safety devices.
  5. This unit can be used for doing applied research.
  6. This unit can be used for giving training courses to Industries even to other Technical Education Institutions.
  7. Control of the AEDC/A unit process through the control interface box without the computer.
  8. Visualization of all the sensors values used in the AEDC/A unit process.
  9. Several other exercises can be done and designed by the user.
