How to find the volume change of CO2 when compressed into liquid?

Click For Summary
SUMMARY

The discussion focuses on calculating the liquid volume of CO2 when compressed from a gas volume of 4.14x10-6 m3 at -20°C and 1 bar to a liquid state at 25 bar, maintaining the same temperature. Participants recommend using the Span and Wagner (1996) reference for accurate properties of CO2 under these conditions. Additionally, an online calculator is suggested for those at an undergraduate level to assist with the calculations. The conversation emphasizes the importance of established scientific literature for postgraduate research.

PREREQUISITES
  • Understanding of thermodynamics and phase changes
  • Familiarity with CO2 properties and behavior under pressure
  • Knowledge of the Span and Wagner correlation for CO2
  • Experience with using scientific calculators or software for thermodynamic properties
NEXT STEPS
  • Research the Span and Wagner (1996) correlation for CO2 properties
  • Learn how to use thermodynamic calculators for gas-to-liquid transitions
  • Explore the effects of pressure on gas volume and phase changes
  • Investigate the implications of temperature stability during compression
USEFUL FOR

Graduate students, researchers in thermodynamics, and professionals working with gas compression and phase transitions will benefit from this discussion.

Can anyone guide me with an approach to find the liquid volume of CO2 when a gas of 4.14x10[SUP]-6[/SUP] m[SUP]3[/SUP] at -20°C and 1 bar is compressed to liquid at 25bar, without change in temperature?
Hi,

Hi there
Welcome to PF :smile:

you have tagged your thread with an A, for post graduate level. Are you really there ?
If so, you must be well used to doing research ... what have you found so far online that
helps you with an answer ?

PS... is this really homework ?

Starting from an undergrad level of competence, Google was able to point to a calculator that yields the relevant properties. For grad level, see Span and Wagner, 1996, J. Phys. Chem. Ref. Data., 25, 1509-1596
