EFFECT OF HYDROCARBON ON THE ACTION OF CO2 CORROSION INHIBITORS
Abstract
This research focused on a study of hydrocarbon effect on action of carbon dioxide
corrosion inhibitors. Wheel test was used to determine the effectiveness of each
inhibitor in the presence and absence of hydrocarbon at 50oC. The effects of
hydrocarbon on the action of compounds used in this work gave different result on each
compound. Oligomer of P4VP is chemisorbed on the mild steel surface shows that no
significant effect of hydrocarbon. The corrosion rate of P2VP oligomer increases by
adding hydrocarbon. Whole surfactants that were tested hydrocarbon effect show
increasing corrosion rate in the presence of hydrocarbon due to the simple desorption of
inhibitor from the surface.
