AbstractBubble columns are form commend industrial instruments which is widely used in factorial petrochemical and biochemical aspects especially in absorption and reactions between gas and the liquid. The study aimed to study the effects of both the superficial gas velocity for ranges (15- 2.24) ×〖10〗^(-2) m /s and pressure ranges for (0.5-2) kg/ cm2 and diameter holes (1,2,2.5) mm in gas distributor from perforated plate for electrolytic solutions (0.05 N NaCl, 0.02 N CaCl2, 0.1 N Na2SO4 ) to volume percentage for holden gas in solution and mass transfer coefficient ratio. The experimental device was used on the bubble column length (2m) diameter (0.2) m and thickness (0.01) m.
The study result show that high volumetric percent at concentration (0.02 N CaCl2 ) was (7.65) due to its dependence on superficial gas velocity while the higher volume holdup gas in solution at concentration( 0.05 N Nacl) was (7.96) because of higher pressure which cause in decreasing the mass transfer coefficient ratio which is increase with the gas superficial surface in solution at concentration level ( 0.1 N Na2SO4 ) and the is occur due to bubble volume is higher when pressure increase.
