The Computer Controlled Liquid-Liquid Extraction Unit, allows to study the extraction of one or several components in a continuous way with a solvent.
Technical Specifications
ATENG 10813 — Computer Controlled Liquid-Liquid Extraction Unit
(for main items)
With this unit there are several options and possibilities:
Main items: 1, 2, 3, 4, 5 and 6.
Optional items: 7, 8, 9, 10 and 11.
Let us describe first the main items (1 to 6):
1UELLC. Unit:
Anodized aluminum frame and panels made of painted steel.
The unit includes wheels to facilitate its mobility.
Main metallic elements made of stainless steel.
Diagram in the front panel with distribution of the elements similar to the real one.
Transparent elements for a better observation of the process.
Extraction process:
Jacketed glass column packed with glass Raschig rings:
Length: 1200 mm.
Internal diameter: 50 mm.
Two enlargement pieces at the ends, capacity: 2 l.
Distillation process:
Boiler for the distillation, heated by an adjustable electric heating mantle and with control
of the temperature; capacity: 5 l.
Jacketed glass column packed with glass Raschig rings:
Length: 500 mm.
Internal diameter: 25 mm.
Coolant column.
Five Pyrex storage tanks for the feed, refined, solvent, extract and solute, capacity (each one):
10 l. They include drain valves and force sensors to measure the stored liquid mass; force
sensors range: 0 – 15 Kg.
Supply circuits and product collection circuits to connect the different components of the unit.
They include five sampling taps, distributed between all the circuits of the unit, to control
the process in all the pipelines of fluid, three-way directional valves, drain valves and a
regulating valve.
Two computer controlled diaphragm pumps: Unit: ATENG 10813
Computer controlled diaphragm pump with stainless steel head to pump the feed, max. flow: 47 l/h,
max. pressure: 5 bar.
Computer controlled diaphragm pump with stainless steel head to pump the solvent, max. flow: 17 l/h,
max. pressure: 5 bar.
Computer controlled electrical heating mantle, power: 800 W.
Two “J type” temperature sensors to measure the temperature in the column head and the boiler
temperature in the distillation process.
Two flowmeters to measure the feed and solvent flow:
Flowmeter for acetic acid 4%, range: 0 – 48 l/h
Flowmeter for trichloromethane, range: 0 – 17 l/h.
The unit includes safety devices in the pumps to avoid shortcomings by overpressure. There are two
pressure switches that switch off the pumps when the pressure is high.
The complete unit includes as well:
Advanced Real-Time SCADA and PID Control.
Open Control + Multicontrol + Real-Time Control.
Specialized Control Software based on LabVIEW.
National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
Calibration exercises, which are included, teach the user how to calibrate a sensor and the
importance of checking the accuracy of the sensors before taking measurements.
Projector and/or electronic whiteboard compatibility allows the unit to be explained and
demonstrated to an entire class at one time.
Capable of doing applied research, real industrial simulation, training courses, etc.
Remote operation and control by the user and remote control for technical support,
are always included.
Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).
Designed and manufactured under several quality standards.
Optional ICAI software to create, edit and carry out practical exercises, tests, exams,
calculations, etc. Apart from monitoring user's knowledge and progress reached.
This unit has been designed for future expansion and integration. A common expansion is
the Scada-Net (ESN) System which enables multiple students to simultaneously
operate many units in a network.
