Online calculator, figures and tables showing density and specific weight of carbon dioxide, CO 2 , at temperatures ranging from -50 to 775 °C (-50 to 1400 °F) at atmospheric and higher pressure - Imperial and SI Units.

Liquid carbon dioxide is being considered as a means of CO 2 transportation for underground or subsea storage purposes. Due to its high density as a liquid, it is much more feasible to ship than as a gas.

Online calculator, figures and tables showing density and specific weight of carbon dioxide, CO 2, at temperatures ranging from -50 to 775 °C (-50 to 1400 °F) at atmospheric and higher pressure - Imperial and SI Units.

The table below gives thermodynamic data of liquid CO 2 in equilibrium with its vapor at various temperatures. Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0 °C temperature and 3483 kPa pressure.

Calculate online thermodynamic and transport properties of carbon dioxide based on industrial formulation (formulated in Helmholtz energy) for advanced technical applications.

Carbon dioxide is an essential gas for life. It functions as a Green House Gas (GHG) maintaining livable conditions on Earth. Carbon dioxide gas has a slightly irritating odor, is colorless and heavier than air. It freezes at -78.5 °C to form carbon dioxide snow, used in fired extinguishers.

The density of CO2 at different temperatures and pressures is plotted below. Liquefied CO2 will be in the range of 1,000-1,200kg/m3, which is over 2x more dense than LNG. Moreover, the density of heated CO2 at 300-bar and 600C is 170kg/m3, which is 2x higher than the equivalent density of steam.

Carbon dioxide has no liquid state at pressures below 5.1 atm. At 1 atm it is a solid at temperatures below −78 °C. In its solid state, carbon dioxide is commonly called dry ice. CO 2 is an acidic oxide: an aqueous solution turns litmus from blue to pink.
