3. PILOT PLANT ABSORPTION OF GASES
3.1. Main parts of the pilot plant
The pilot plant consists of the following elements arranged convenient way to make it work.
1- Flow meter of CO2.
2- Air flow meter.
3- Bourdon type manometer.
4- Water flow meter.
5- Column absorption with filling.
6- Devices for measuring the differential pressure.
7- Silencer.
8- Deposit and depression manometer.
9- Recirculation pump.
10- Pump of carbon dioxide.
11- Distribution box.
12- Water tank.
13- Water pumps.

The main features of the team are:
- Length x width x height of the team : 950 x 750 x 2310 mm.
- Power Supply a 50-60Hz: 230V.
- Approximate weight: 135 kg.
- Diameter x height of the column filling: 90x560 mm.
- Material column: Glass DURAN with glass stainless steel 1,4305.
- Body filling: Rasching rings.
- Filling material: sodium carbonate-lime glass.
- Diameter x height filling : 10x10 mm.
The operation of the team is as follows: the left side of the team are the distribution box, which is where the team is turned on or turned off. Once we launch, the device must connect the compressor. This compressor is located behind the panel elements, where there is a security box. This compressor can take the free air and compress it in order to introduce it into the column. Along the security box is located the junction with the air of CO2, so the air and CO2 come together in column. To capture the carbon dioxide is carried out with tap water. To verify that the water picks up carbon dioxide are taken sample at three points located: one at the entrance of the column (point 1), the other in half of the column (point 2) and last point is the output of the column (point 3). We must analyze the water, checking the pH or by an assessment of carbonates, to see if it is saturated with CO2. When water is saturated is when we use the deposit of depression. From the pump, clean water and carbon dioxide can be reused.
Must say that this team is not used for industrial production but also serves to train students.
