Corrosion and Scale Inhibition Effects of Inhibitors for Natural Gas Dehydration Unit

The effects of dosage,corrosion time,pH value of solution and ratio of the components on corrosion and scale inhibition for the glycol dehydration unit of natural gas shallow refrigeration plant were studied and the optimal corrosion inhibitor was obtained.The corrosion inhibition efficiency of the optimal corrosion inhibitor reached 93.82% under experimental condition,and the average corrosion inhibition efficiency was 74% in field application in the glycol dehydration unit of natural gas shallow refrigeration plant.
