1. The hydrocarbon tail attracts oil molecules from the fluid. Inhibitor molecule, consisting of a polar nitrogen group with a hydrocarbon tail, is dispersed in process stream. Polar nitrogen group Hydrocarbon Tail Oil W H2S CO2 O2 Oil Oil Polar group adsorbs onto the surface of the pipe. The hydrocarbon tail and oil molecules shield the pipe surface from the corrosive water phase. Pipe Surface
