CARBON DIOXIDE (CO2)

Carbon Dioxide (CO2) is a slightly toxic, odorless, colorless gas with a slightly pungent, acid taste. CO2 is commercially obtained as a by-product from a variety of sources including the manufacture of various chemicals (principally ammonia and hydrogen), thermal decomposition of carbonaceous materials, fermentation processes, Gases present in natural wells, geothermal sources, or produced from fuel combustion.

Beverage grade Carbon Dioxide is used in large quantities in the manufacture of carbonated Beverages, mostly soft drinks. All Food and Beverage grade CO2 undergoes a purification process; sometimes trace impurities make their way into the supply. The purity of Carbon Dioxide plays a key role in the quality & taste of the Beverage. It is thus essential to check the CO2 impurities before being used for Food & Beverages. The presence of Sulfur and certain Hydrocarbons in Carbon Dioxide gas can be corrosive, poisonous, and odorous.

Carbon Dioxide gas is used in Food and Beverages, Health Care, Rubber and Plastics Industry, Chemicals, Pharmaceuticals, Petroleum & Metals Industry.

[Carbon Dioxide (CO₂), an odorless, colorless, mildly – pungent & toxic gas is acidic in taste. CO₂ is commercially obtained from a variety of sources including as a “by-product” during the manufacture of various chemicals (principally ammonia and hydrogen), thermal decomposition of carbonaceous materials, fermentation processes, and from Gases present in natural wells, geothermal sources, or as a byproduct in fuel combustion.

Carbon Dioxide gas is used in Food and Beverage, Health Care, Rubber and Plastic Industry, Chemical and Pharmaceutical, and Petroleum & Metal industries. Beverage grade CO₂ is used in large quantities in Food Sector, mostly in the manufacture of carbonated Soft drinks. The purity of CO_2,being key to the quality & taste of Beverages, needs to be purified of trace impurities originating from the raw gas source or from contamination during storage and distribution. It is thus essential to ascertain the extent of impurity prior to its use. Sulfur and certain Hydrocarbons, if present is corrosive, poisonous, and odorous.
