Beverage Carbon Dioxide Purification

Pellet activated carbon guard bed for beverage grade carbon dioxide purification meeting ISBT (International Society of Beverage Technologists) specifications for carbonated soft drinks, beer, and sparkling water.

Find My Solution View Products & Systems
The Challenge
Beverage grade CO₂ for carbonated soft drinks, beer, and sparkling water must meet the ISBT specification: sulphur compounds below 0.1 ppm, total volatile hydrocarbons below 20 ppm, aromatic hydrocarbons below 20 ppb, acetaldehyde below 0.2 ppm. The raw CO₂ from any source carries trace contaminants that fail this specification.
Quick Answer

Beverage carbon dioxide purification uses a pellet activated carbon guard bed to remove trace sulphur compounds, total hydrocarbons, aromatic hydrocarbons, and acetaldehyde from CO₂ sourced from ammonia plant by product, ethanol fermentation, or natural well CO₂. Outlet meets ISBT (International Society of Beverage Technologists) beverage grade purity.

Beverage Carbon Dioxide Purification

Beverage Grade CO₂ Has Tight Specifications

CO₂ for carbonated soft drinks, beer, and sparkling water must meet the ISBT (International Society of Beverage Technologists) specification, the industry standard published by the International Society of Beverage Technologists. The critical limits are sulphur compounds below 0.1 ppm, total volatile hydrocarbons below 20 ppm, aromatic hydrocarbons (benzene, toluene) below 20 ppb, and acetaldehyde below 0.2 ppm. These limits protect consumer safety and product taste.

Trace Contaminants in Raw CO₂

Raw CO₂ sources carry different trace contaminants. Ammonia plant by product CO₂ carries trace ammonia and amine residue; ethanol fermentation CO₂ carries acetaldehyde, ethanol, and fusel oils; natural well CO₂ carries trace methane, ethane, and sulphur compounds. The beverage plant purification unit must remove all three contaminant classes to meet the ISBT specification reliably.

Beverage Carbon Dioxide Purification process equipment

Pellet Activated Carbon Guard Bed

The SorbiTech purification stage uses a pellet activated carbon guard bed at the CO₂ purification unit, downstream of the bulk water removal and ahead of the final filtration. The bed captures the trace sulphur compounds, the aromatic hydrocarbons, the acetaldehyde, and the heavier hydrocarbons. The pellet form gives low pressure drop at the high gas flows of the CO₂ purification skid.

Delivery and Food Grade Documentation

Delivered as a packaged guard bed by SorbiTech or as a SorbiTech media supply contract for an existing CO₂ purification unit. Every shipment ships with the food grade certificate of analysis, the Halal and Kosher certification, and the ISBT compliance documentation. Sector coverage is food and beverage.

Selection Guidance

Pellet activated carbon guard bed sized for the CO₂ flow and the contracted contaminant load. Operating at the CO₂ pressure (typically 10 to 20 barg). Bed life typically 3 to 5 years before replacement.
