FEED GAS PRETREATMENT For gas feeds commonly applied apparatus includes knockout drums filter-separators or a water wash drum or column. Amine plants consist basically of two units Figure 21. Amine absorber column design.
Amine Absorber Column Design, While simulating in Promax you can specify maximum limit up to 85. Able limit of absorber column. One important design factor of absorber columns is the gas velocity through the absorber packing. Their design comprised of a single absorber with a 913 m diameter and a height of 269 m and a single stripper with a diameter of 55 m and a height of 235 m.

Usually the absorber is a tray column although packed col- umns are also used. First all four streams are fed to the absorber at 40C and are saturated with water. This model does for mass transfer columns what modern heat transfer methodology has done for heat exchanger design. One important design factor of absorber columns is the gas velocity through the absorber packing.
In this example show how you can design and sizing a packed bed adsorbed to remove HCL from air stream by water.
