Question 75

Naphthenic acid corrosion is most severe in _________ flow; in areas of high velocity or turbulence and in distillation towers where hot vapors condense to form liquid phase droplets.

    Correct Answer: B

    Naphthenic acid corrosion is most severe in two-phase flow, in areas where there is a mixture of liquid and vapor. These conditions tend to create high velocity or turbulence, and in distillation towers, hot vapors condense to form liquid droplets, which increase the rate of corrosion.

Discussion
