What is CO2 ?
Carbon Dioxide ia a chemical compound formed by combining one atom of carbon with two atoms of oxygen and is expressed by the chemical symbol CO2.
Under normal atmospheric temperatures and pressures, carbon dioxide exists as a colorless, odorless, non-toxic gas, which is about 1.5 times heavier than air.
Carbon dioxide will not burn, support combustion and will not sustain life.
Carbon dioxide can exist in one or all three states of matter: solid, liquid and a gas depending upon conditions of temperature and pressure.
The point at which all three may exist in-69.90F (-56.60C) and 60.4 psig (416.7 kPa) is called triple point.
The critical point of carbon dioxide is 87.90F (31.10C) and 1056 psig (7281 kPa). At temperatures and pressures above these critical points, carbon dioxide liquid cannot exist.
The term "low pressure" is used in the industry to describe the storage of carbon dioxide at pressures below 350 psig
( 2413.2 kPa).
