Josip:

Thank you! I finally see the error of my ways. I was looking at the chart with my eyes, but not "seeing" what would be happening to the dry ice in my example. I was missing the vertical line completely.

My concern over this matter is that during routine maintenance and repair we will have to access parts of our recovery system which contain liquid CO2. Along with personnel safety, we have to protect the equipment as well and I wanted to fully understand how the CO2 would behave when accessing the system components. Our policy is to remove liquid CO2 from the component being accessed as a liquid, then de-pressurize after the liquid is gone. Your explanation will help me to more accurately explain our proceedures to the boss.

Thank you again, sir. Extremely well said.
