Reaction rate of caustic with CO2
Reaction rate of caustic with CO2
(OP)
HI
I am going to design a caustic wash tower in ehtylene plant.Is there any one help me to find kenetic formula of the reaction between CO2 and NAOH.
Thank you

RE: Reaction rate of caustic with CO2
I found in the literature the Arrhenius equation:
where:
A = 1.5×1010 L/(mol.s)
Ea = 38 kJ/mol
R = 8.314×10-3 kJ/(mol.K)
T = temperature, K
From the equilibrium reactions I infer that at pH~8.5 the dominant ion would be the bicarbonate, at high pH values carbonate predominates, at pH~10.5 carbonate and bicarbonate would have about equal concentrations.
