What is the phase diagram of CO2?
- The phase diagram for carbon dioxide shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the carbon dioxide boiling point with changes in pressure.
What is the purpose of a phase diagram?
- A phase diagram in physical chemistry, engineering, mineralogy, and materials science is a type of chart used to show conditions (pressure, temperature, volume, etc.) at which thermodynamically distinct phases (such as solid, liquid or gaseous states) occur and coexist at equilibrium .
What is the difference between a phase diagram and a pressure-temperature diagram?
- In a phase diagram temperature values are drawn on x-axis, whereas pressure values on y-axis. If we will keep the pressure value constant on the y-axis and increase the temperature, a substance will be converted into a liquid phase from its solid phase.
What is the critical point of CO2?
- Since the critical point for CO 2 is 31.1 o C and 7.38 MPa, the system pressure higher than 7.5 MPa results in transportation at supercritical parameters, as long as the temperature remains above 31.1 o C.
