Carbon dioxide (liquid) – CO2
Carbon dioxide under normal conditions is a colourless, odourless gas, and of slightly sour taste. It is denser than air, inert, and non-combustible. It is liquefied at a pressure of 15 to 17 bar and temperature -30 to -35°C. CO2 is not toxic and is present in the atmosphere at a concentration of about 0.03 vol. %. Higher concentrations are dangerous due to the reduction of oxygen in the air.
Belinka Perkemija produces liquid CO2 to the quality required by the food industry.
CO2 is used:
In food industry for:
- aerating beverages,
- the manufacture and packaging of food in an inert atmosphere,
- decantation of beer,
- cooling of food during transport,
- water softening.
In foundry industry:
- for hardening of foundry cores,
- for cleaning in steel processing,
- as a blowing gas in casting.
In chemical industry:
- as a protective gas for chemical synthesis,
- as a neutralizing agent,
- for the production of carbonates,
- for supercritical extraction,
- for grinding of granules,
- for the production of hollow-blown plastic.
In biology and medicine:
- as a means of extinguishing fires in electrical installations and various chemicals,
- as a coolant for various purposes.
