Carbon dioxide was absorbed by aqueous Carbopol solutions in a turbine‐agitated vessel for the cases of absorption across an unbroken interface and absorption with the gas bubbling through the liquid. The rheological behavior of the solutions was described by the non‐Newtonian power law model with flow behavior indices varying from 0.92 to 0.59. An effective viscosity technique which had previously been developed to correlate agitated vessel rates of viscous dissipation and heat transfer with power law pseudoplastic fluids was used to correlate the data.
