Dear All,

 

I am operating a flue gas co2 recovery plant in Pakistan. I wanted to know will liquid co2 automatically flow into the storage tank form the shell and tube heat exchanger once liquified??. How will I know if co2 is being liquified and being transferred into tank rather than in just gas form??. Is there a need of installing a valve onto the line going from the liquefaction unit to the tank?

 

 

Regards,

Hasan

Hasan:

 

Gravity flow from the CO₂ condenser and into a storage tank is being done every day.

 

You know the CO₂ compressed gas is being liquefied because the condenser vapor space remains as the CO₂ saturation pressure (usually around 250 psig - and the liquid level in the tank increases steadily.

 

You need a valve to isolate the tank upon shutdown.
