Hey everyone
i'm in the process of designing an absorption tower (packed) to remove pure CO2 from a natural gas stream flowing at 25 MMscfd.
The natural gas contains 8% CO2 initially, and must contain 3% CO2 on exiting the tower.
The feed gas inlet conditions are 298K and 6900kPa
i've decided to use a propylene carbonate solvent
The CO2 absorption into the solvent at the process conditions follows henrys law
Basically i want to know how i would go about calculating the number of overall gas transfer units required to reach the 3% CO2 specification.
