Carbon Dioxide Absorption in Packed Column in

Tikrit Journal of Engineering Sciences, 2013
Absorption of carbon dioxide into carbonate solution (Na2CO3) with PAM (non-Newtonian fluid) has been performed in a countercurrent packed column (0.075m i.d. *1.25 m height) packed with glass Raschig rings (1*1cm) to a depth of 1m.
