Corrosion inhibitors for petroleum refinery and petrochemical operations

Organic corrosion inhibitors have been used to control process-side corrosion in petroleum refineries and petrochemical plants for many years. This review describes the type of corrosion problems which have lent themselves to inhibitor application, the probable mechanism of protection, and certain process limitations that should be considered. Also covered are various test methods for the evaluations of organic corrosion inhibitors.
