Study on the Corrosion of Carbon Steel in Gasoil-Brine Mixture in presence of acid
Abstract
Corrosion tests of carbon steel in two phase flow of two immiscible liquids (CaCO3 solution-gasoil mixture) under different operating conditions of temperature, agitation velocity, and phase fractions, were carried out using weigh loss method. Flat blade disc turbine mixer was used to simulate the two phase flow conditions. In two immiscible phases tests, the ranges of operating parameters were agitation velocities of 0 - 1200 rpm, temperature of 25- 45 oC, gasoil volume percent of 1-10% vol. The effect of presence of acids such as HCl and H2SO4 on the corrosion rate in two immiscible phases mixture was also investigated under different conditions. The corrosion rate in brine-gasoil mixture had unstable trend with concentration of gasoil and rotational velocity.
