ATENG 10838 — Computer Controlled Gas Absorption Column
(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):
- 1 ATENG 10838. 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.
- Packed column:
- It consists of a glass cylindrical column of 1400 mm of height and 75 mm of internal diameter.
- It is filled with Raschig rings of 10 mm diameter.
It includes glass ends for inlet and outlet of gases and liquids and for sample point.
Two differential pressure sensors. The pressure can be measure in different parts of the column.
- Liquid circuit (water):
- PVC glass storage tank, capacity: 40 l.
- Computer controlled centrifugal pump, maximum flow rate: 540 l/h.
The liquid flow that arrives at each moment to the column is measured with a flow sensor,
- range: 0.25 – 6.5 l/min and a flowmeter.
Liquid flow is controlled by PID control.
Glass diffusion shower.
PVC conduit for the effluent liquid with a control flow valve and one sampler.
“J” type temperature sensor to measure the inlet temperature of water into the column.
- Gas circuit (air and CO ):
Compressor (blower), computer controlled, provides a maximum flow of 6 m³/h and a maximum
- pressure of 1 bar.
The gas (CO or ammonia) is supplied by a cylinder, type bottle. (Not supplied with the unit)
Mixing system for the two gases streams.
Both gas flows are measured by sensors (two differential pressure sensors) and two flowmeters
- Unit: ATENG 10838
installed in the panel.
Two control flow valves.
“J” type temperature sensor to measure the temperature of the mixture of both gas flows at the inlet
of the column.
- Instrumentation for the analytical measurement of CO :
Glass syringe of 100 ml capacity, dedicated to extract the specific quantities of a sample to be
analysed.
Two glass tanks located at different heights and interconnected. They contain an aqueous solution of
KOH, in which the contained CO will be absorbed in the sample of gas to analyze.
Three way-valves to direct the gaseous currents during the analysis process.
- Sensor to measure the concentration of CO in a gaseous current directly, range: 0 – 100 %.
There are transparent elements allowing a better visualization of the process.
- 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.
