DECARBITE®

DECARBITE® should be used for the rapid or high performance quantitative absorption of CO₂.

Removing Carbon Dioxide

The absorption of carbon dioxide removal or any acid gas using DECARBITE® is a chemical reaction, not a physical one. Carbon dioxide reacts with the sodium hydroxide based absorbent and undergoes a complete chemical change. This change is irreversible; therefore the absorbent cannot be regenerated for reuse.

A small percentage of moisture present in the absorbent material (about 3%) is important. CO₂ reacts with this moisture to form carbonic acid, which in turn reacts with the hydroxide to form the salt of carbonic acid, or sodium carbonate .The absorption of carbon dioxide is expressed as follows:

CO_₂ + H_₂O → H₂CO₃

2NaOH + H₂CO₃ → Na₂CO₃ + 2H₂O

The products of reaction are sodium carbonate and water. DECARBITE® is disposable absorbent product.

DECARBITE® is color indicating, changing from tan to white upon carbon dioxide saturation. This change is clearly perceptible and indicates when spent material is to be discarded.

Occasionally, a condition known as channeling can occur when the gas flow finds holes or areas of least resistance. The gas flow follows these channels through the absorbent defeating the purpose of scrubbing out the carbon dioxide. DECARBITE® eliminates this problem in several ways; the silica binding to the sodium hydroxide keeps the particles from bonding in the presence of moisture which is formed as a by product of the absorption reaction. It also aids in preventing the absorbent to coalesce into a solid mass blocking gas flow and causing back pressure across the absorption bed.

Capacity

DECARBITE® absorbs more than 40% of its own weight under normal conditions.

System Design

Usually, transparent canisters or cylindrical tubes are used as this permits the visual inspection of the reaction during the removal of carbon dioxide from a gas stream. Such containers may be referred to as CO₂ Getters, CO₂ Scrubbers, CO₂ Traps, CO₂ Purifiers, CO₂ Filters, Compress Gas Purifiers or CO₂ Trap Cartridges. When glass tubes are used, they must be manufactured to resist high temperatures and corrosive effects.

Gas Flow

High gas flows impede the efficiency of the gas absorption by limiting the time of contact between the gas and the absorbent material. DECARBITE® granules have irregular surface areas and do not readily compact or fit together. The holding apart of the granules creates voids that allows for uniform gas flow and higher permeability. Gas flow resistance varies with particle size. Larger particle size (8-14 mesh range) allows greater space between particles and less resistance to gas flow (also smaller surface area). Smaller mesh size (14-30 mesh range) have a larger over all surface area . The smaller particle size is the more efficient for fractional percentages of carbon dioxide absorption.

• Manufacturing

DECARBITE® is used for the rapid or high performance quantitative absorption of carbon dioxide from gas streams, for scrubbing residual carbon dioxide from atmospheric gasses, for use in carbon-hydrogen determinations, carbon dioxide removal from atmospheric gasses, and various applications where carbon dioxide is an unwanted by-product gas.

DECARBITE® finds a wide range of applications as a CO₂ getter, CO₂ Scrubbers, CO₂ Traps, CO₂ Purifiers, CO₂ Filters, Compressed Gas Purifiers or CO₂ Trap Cartridge. Reducing the presence of CO₂ in gas streams to the ppm range is especially critical in analytical applications where ultra pure carrier gas is a must.

DECARBITE® may be used in heat applications that generate CO2 as an unwanted contaminate gas in particular industrial applications.

Note: DECARBITE® is not recommended for use in re-breathing systems such as anesthesia, closed systems, or under water self contained units.

DECARBITE® will absorb in excess of 40% of the material weight at standard temperature pressure (STP) under optimal conditions. 100g of DECARBITE® will absorb 40g of CO₂ at flow rates of 100ml/min.

The CO₂ removing product DECARBITE®, has a built in indicator that allows the visual observation of the reaction process. The material turns from tan to white and is clearly perceptual as the absorbent is exhausted.
