Make Liquid Co2

Co2 (CO2) is really a gas at standard temperature and pressure and comprises about .04 percent from the Earth's atmosphere. Liquid co2 is much more easily moved than co2 gas, and it has programs in refrigeration and industrial chemistry. This is an unusual compound for the reason that solid co2 sublimates (disappears) from the solid towards the gaseous condition under standard conditions. Co2 liquefaction requires repeated programs of cooling and pressure.

Instructions

1. Find out the critical temperature for co2 as 88 levels Fahrenheit. This is actually the maximum temperature where co2 could be a liquid. The entire process of liquefying co2 must therefore keep your liquid below 88 levels Fahrenheit.

2. Determine the minimum pressure required to keep co2 a liquid. Co2 should be pressurized to a minimum of 5.1 atm to stay a liquid, regardless of how cold it's.

3. Compress co2 to around 56 atm at 70 degrees. This process may be the easiest to show, but can also be probably the most inefficient and it is therefore rarely used in a commercial sense.

4. Result in the co2 prevent some exterior pressure. Awesome the co2 and drive it via a turbine. The gas manages to lose energy because it works work and it is temperature drops further. The gas can eventually lose enough energy to become liquid.

5. Make use of the Joule-Thomson effect to show co2 gas right into a liquid. Pump the gas right into a container pressurized via a one-way valve. Release the valve to ensure that the gas grows, cooling because it achieves this. Continue doing this process before the gas turns into a liquid.
