Studies on the mechanical loss of hydrogen taking place in CO2-Absorbing-Tower

Department of Applied Chemistry, Faculty of Engineering, Osaka University. For the purpose of explanation of the mechanical loss of hydrogen taking place in CO2-absorbing tower, we tried some model experiments in which gas volumes sucked at the tower bottom with circulating liquid were ascertained under various conditions, and by applying dimensional analysis, we have obtained experimental formulas as follows: 1. v/V=5.63×10-12(h/H)4.55(D/d)-1.30(duρ/μ)2.94…h/H4 where H: depth of water layer (cm) h: distance between the surface of water and the inlet pipe (cm) V: Volume of water sucked (cc/min) v: Volume of air sucked with water (cc/min) d: diameter of water pipe (cm) duρ/μ: Reynolds number of the outlet pipe.
