Recovery And Purification of CO2

Recovery and purification of CO2

Carbon dioxide recovery devices are currently widely used in the beverage and food industries, and are also the most economical method for producing high-purity food grade carbon dioxide, provided that there is sufficient quantity and quality of crude carbon dioxide gas.

The carbon dioxide recovery device is mainly used for the washing, purification, drying, liquefaction, and storage of CO2 gas received from the fermentation process, calcium chloride reaction process, and dry ice production process in breweries and distilleries. The carbon dioxide recovery device is automatic and requires the lowest operating cost.

Characteristics of recycling equipment

6 Low maintenance costs

Recovery of CO2

The fermentation process in breweries and distilleries

Industrial processes/fuel gases

Various sources - brewery fermentation, natural wells, or by-products from chemical processing industries. Based on advanced purification processes, purification technology removes any impurities from the primary purification stage, and then in a CO2 compressor, deodorization&drying, liquefaction&stripping are carried out to reduce odors, moisture, and non condensable impurities to an acceptable level.

This innovative technological solution enriches the factory's ability to recover up to 99.99% of delivered carbon dioxide purity.
