Brand Name: Akrosorb

Akrosorb (Soda lime) is a Carbon Dioxide absorbent used for removal of CO2 mainly from breathable gases, in medical, military, diving, mining and safety applications.
Akrosorb (Soda Lime) is an active compound of mixture of hydroxides. This active compound is formed by mixing calcium and sodium hydroxides that has high affinity for Carbon Dioxide. It is supplied as hard, porous, irregularly shaped granules or uniform shaped granules (as per customer specifications) . These granules have been processed to maximize Co2 Absorption and minimize dust formation.

Akrosorb (Soda Lime) is available in a number of different grades, depending on the application.

State of art manufacturing process used for Akrosorb (Soda Lime) ensures that dust formation is minimized and no blockage of canister mesh or circuit piping takes place.


Akrosorb (Soda Lime) removes CO2 from breathable gases in:
Akrosorb (Soda Lime) is used to absorb expired CO2 during Anesthesia (in operation theatres) .
It is used for removing Carbon Dioxide from oxygen-based metabolism, in estimation respirators, breathing apparatus, diving rebreathers.
Akrosorb (Soda Lime) removes CO2 from manned closed atmospheres, such as submarine, and closed circuit breathing apparatus, such as rebreathers.
It is extensively used in navies, for use by divers in submarines.

Akrosorb for Medical Application:
Medical grade Soda Lime is produced as per pharmacopoeia (IP/BP/USP) standards. The particles are extrudates with an irregular shaped profile that ensures maximum CO2 penetration into the particles, by minimizing the distance to the centre of the particle. Akrosorb (Soda Lime) is used to absorb expired Co2 during anesthesia (in operation theatres) , in medical anesthetic breathing circuits, hyperbaric oxygen treatment chambers.
Akrosorb has application in Anesthetic systems in the medical operations to remove expelled Carbon dioxide due to respiration carried out by the patient or the user.

Diving and Safety Application:
Akrosorb (Soda Lime) removes carbon dioxide from the exhaled breath of a diver using a rebreather.
Akrosorb (Soda Lime) is used in navies, for use in submarines, in naval and tourist vessels and by divers.
It absorbs carbon dioxide in helium-oxygen breathing systems, hyperbaric chambers and scuba apparatus, diving rebreathers, saturation dive system for commercial deep sea diving, commercial & leisure diving rebreathers.

Application in Military (Submarines) :
Akrosorb finds application in Military and Commercial Rebreather sets to take away exhaled CO2.
Submarines have a complex air filtration system, essential for maintaining the atmosphere within the submarine suitable for breathing whilst submerged. The carbon dioxide scrubbing system removes the CO2, generated via respiration, by constant circulation through a scrubber system filled with Akrosorb (Soda Lime) .

Akrosorb absorbs CO2 in personnel rebreathers for mine (miners gas mask) , fire and other safety systemsIt is also used in oxygen-based metabolism, in estimation respirators, breathing apparatus etc.

Petrochemical Industry
Akrosorb (Soda Lime) can be used in the petrochemical industry for removal of trace acidic contaminants (CO2) in the production of high purity hydrocarbons such as propylene and ethylene.
