General Information about CO
2
Horizontal CO 2 storage tank Vertical CO 2 storage tank ISO container for transportation of CO 2The Gaseous State
CO
2
gas has a density of approx. 1.9kg/m
3
(0.12 lb/ft
3
) at atmospheric pressure and +15 °C. CO
2
has many unique
and beneficial features which make it valuable in the preservation of packaged food, in explosion and fire protection,
in pest control and as protectivegas in inert-gas-welding. In all these applications it is important for the CO
2
gas to
drive out and replace the atmospheric oxygen. Moreover, CO
2
gas is used for enriching the atmosphere in green-
houses, in storing fruits and vegetables and for pH control when treating potable and waste water.

The critical point of CO
2
lies at a temperature of approx. 31 °C and a pressure of approx. 74 bar (58.02psi). Normal
CO
2
liquid can only be formed at temperatures below 31 °C. Above the critical point there is no physical difference
between the liquid and gaseous phase. This supercritical state is also called „Fluid“. The liquid state is important
for the storage and transportation of CO
2
as well as during cooling and freezing applications. During release of the
liquid CO
2
to atmosphere a temperature of -79 °C is reached. This is associated with a high cooling capacity due to
the evaporation heat which is extracted from the environment when releasing the liquid CO
2
.
