- Automatic System for CO2
Recovery and Storage
The automatic ASCO2
Recovery System absorbs CO2 from
outdoor air. Then, the system releases the pure CO2 gas through a
vacuum pump - compressor system into high
pressure storage bottles or other high pressure storage systems.
The quantities of enrichment of our standard ASCO2
vary by model between a few milligrams and 20 kg per hour, but we also deliver
tailored systems according to the client need.
The patented technology is based on the
Carbon Dioxide filtration technologies developed originally for modern
submarines. In a submarine, the members of the crew produce Carbon Dioxide in
volumes that would be mortal, if the gas would not be eliminated from the vessel
As the system does not produce CO2,
but only adsorbs it from the air, it is a very environmentally friendly
technology, which can help you in creating a favorable image for your
organization, company or products.
The costs of recovering CO2 using the ASCO2
far below the price of CO2 in the market. In addition to electricity
costs, there are no material or fuel costs related to the CO2
solution. The ASCO2
Dioxide Absorbent service life is well over 5,000 recovery cycles, which means
years of almost maintenance-free operation. And there is no need to continue
carrying the CO2 bottles nor fuels or raw materials to your premises.
The complete autonomy of the Automatic ASCO2
CO2 Recovery System is very long. You switch it on, and it will carry out the
CO2 Recovery automatically, for between 3 and 20 years. It is only
necessary to change the prefilter (for particles in the air) 1 - 4 times a year.
The cost (energy costs included) per a kilogram of CO2 recovered,
is less than half of the corresponding price of CO2 produced by
combustion methods. Also, the cost saving in the form of a dramatic reduction in
labor hours and discontinued contamination of the climate of your premises by
combustion gases have to be considered.
of the Technology
is the principal technology of carbon
dioxide filtration in Building Engineering.
of the Technology
Dioxide Recovery System adsorbs CO2 from the air or other gases and
pressurizes it into high pressure gas storages.
Adsorption of CO2
1) A ventilator blows outdoor air through a CO2
Absorbent Cassette. The carbon dioxide absorbent media is amine impregnated in
polystyrene. The chemical reaction can be described as follows:
Chemical Absorption Reaction, ASCO2
Amine + H2O → (Amine - H2O)
and then (Amine - H2O) + CO2 → (Amine - H2CO3)
2) CO2 is blown to the greenhouse
or to high-pressure storage bottles and the purified air without CO2
is blown back to the atmosphere.
The efficiency of absorption is demonstrated
by tests realized by the Helsinki University of Technology:
Concentration of CO2 in the Air Intake: 350 ppm;
Air Flow: 6 liters / minute = 360 l / h;
Absorbent (Amine) Weight: 25 grams:
The tests show that 25 grams of our patented
Amine can absorb all (100%) of the
350 ppm CO2 in airflow of 360 l/h during 9 hours and 30 minutes.
Desorption of CO2
During the CO2 Adsorbent Regeneration, the adsorbed carbon dioxide is
released by heating the ASCO2
absorbent by hot air blown through the cassette. The warm air is
generated by an internal heater of the equipment or by an autonomous heater.
(Amine - H2CO3) + Heat →
Amine + H2O + CO2
If the heat produced during the process is not
needed, the ASCO2
System can be equipped with a Gas Refrigerator that lowers the
temperature to the level required.
