Abstract
The present work is concerned with the rate of diffusion controlled corrosion of agitated vessels handling emulsions. The study was carried out by measuring the rate of diffusion controlled dissolution of copper in acidified FeCl3 solution containing oil (petroleum) emulsion. Variables studied were (i) Rotation speed of the impeller. (ii) Emulsion composition (% oil by volume). (iii) The effect of drag reducing polymers, namely, polyethylene oxide (polyox).
The study revealed the following results:
(1) The mass transfer coefficient of copper dissolution in acidified FeCl3 containing oil as emulsion has increased with increasing rotation speed of the impeller.
(2) The mass transfer coefficient has decreased with increasing oil concentration in the emulsion.
(3) Polyox addition, in the concentration range from 10-100 ppm, showed an inhibition effect in the turbulent flow regime while in the laminar flow regime it had no effect.
(4) The mass transfer coefficient of the corrosion process was related to other variables by the following dimensionless correlation:
