FLUIDYNE CO2 Absorbers, CO2 Breathers CO2 Scrubbers and CO2 Filters maintain stable pH and low conductivity of demineralised water and prevent carbon dioxide from entering into process water storage tanks and condensate storage tanks. FLUIDYNE manufacture and design highly efficient and rugged CO2 Absorbers, CO2 Breathers, CO2 Scrubbers and CO2 Filters for the removal of CO2 from air during in-breathing during emptying of DM Water or other storage tanks. The FLUIDYNE design is customized based on customer specifications, process data and other technical requirements. FLUIDYNE CO2 Absorbers, CO2 Breathers CO2 Scrubbers and CO2 Filters are installed on the process connection of the tank FLUIDYNE Carbon Breathers absorbers and scrubbers prevent carbon dioxide being absorbed in water by removing CO2 from air flowing into the tank. It is installed on the top cover of the tank for smaller sixes or by pipe connection at ground level for larger sizes. Industries such as chemical, petrochemical, power, electronics and pharmaceutical require highly pure and CO2 free demineralised water. Co2 can contaminate water and increases its conductivity which may not be suitable for most processes. FLUIDYNE CO2 Absorbers, CO2 Breathers CO2 Scrubbers and CO2 Filters are rugged and highly efficient and absorb cent percent of CO2 from the air and ensures highest quality of DM (Demineralised) water. Fluidyne CO2 Absorber Media is highly efficient having long life and 100% absorption potential and indicate by colour change when time has reached to replace it. The advantage of FLUIDYNE CO2 Absorbers, CO2 Breathers CO2 Scrubbers and CO2 Filters is it’s high efficiency, rugged design and ease of maintenance and operation.
CO2 ABSORBER MEDIA
FLUIDYNE CO2 ABSORBER MEDIA CHEMICAL COMPOSITION & REACTION

|CaCl2 % (humectant)
|Polyvinylpyrrolidine % (hardener)
|Water Content %
Percentages are approximations which may not sum to 100%.
THE MAIN COMPOSITION IS CALCIUM OXIDE -- CaO
CaO is produced by heating CaCO3:
CaCO3(s) => CaO(s) + CO2(g)
This above reaction is reversible; calcium oxide will react with carbon dioxide to form calcium carbonate. The reaction is driven to the right by flushing carbon dioxide from the mixture as it is released. CaO can be regenerated by this process by heating CaCO3 at 500 to 600 deg. C in an autoclave furnace.
CaO(s) + H2O(l) => Ca(OH)2(s)
The reaction of calcium hydroxide with carbon dioxide is faster, producing a mortar that hardens more quickly.
Co2 absorption process:
Ca(OH)2(s) + CO2(g) => CaCO3(s) + H2O(l)
CO2 (g) + 2 NaOH (or KOH) --> Na2CO3 (or K2CO3) + 2 H2O + Energy
Na2CO3 (or K2CO3) + Ca (OH)2 --> CaCO3 + 2 NaOH (or KOH)
OTHER Chemical Reactions FOLOWS:
1. CO2 + H2O --> H2CO3
2. H2CO3 + 2 NaOH (or KOH) --> Na2CO3 (or K2CO3) + 2 H2O + Energy
3. Na2CO3 (or K2CO3) + Ca(OH)2 --> CaCO3 + 2 NaOH (or KOH)
#1 is called the first neutralization reaction. In #2 and #3 the second neutralization reaction and the regeneration of activator take place. CaCO3 is an insoluble precipitate.
Additional use of absorber is as stack gas scrubbers to reduce sulfur dioxide emissions from power plants. Sulfur dioxide reacts to form solid calcium sulfite:
SO2(g) + CaO(s) => CaSO3(s)
It is also used to remove phosphates:
3 CaO(s) + 3 H2O(l) + 2 PO43–(aq) => Ca3(PO4)2(s) + 6 OH–(aq)
After signs of exhaustion this reaction takes place:
Changes color on absorption of CO2.
Indicating Type CO2 ABSORBER is available in two forms:
Partical Shape and Size:
- Pink to White on CO2 absorption
- hite to Violet on CO2 absorption
Particle size and shape are particularly important in terms of the performance of Soda lime in its intended application. All granules are irregularly sized, with low dust and excellent attrition resistance.
OTHER APPLICATIONS OF FLUIDYNE CO2 ABSORBER MEDIA
It is also used in pretreatment of water supplies involves to soften, and to clear drinking water. A variety of other industrial processes also is used as an o pacifier in plastics. The paper industry uses it in pulping wood; because it is highly alkaline, it dissolves the lignin that binds the fibers together in wood. In the refining of sugar, it causes coagulation of plant material, allowing it to be more easily separated from the sugar syrup.
