Corrosion control method using methoxypropylamine (mopa) in water-free petroleum and petrochemical process units

摘要

A method of inhibiting corrosion in separation units of water-free petroleum and petrochemical hydrocarbon processing systems which comprises adding a compound corresponding to Formula I below either alone or in combination with a film-forming amine corrosion inhibitor to the hydrocarbon being processed: Formula I R-O-(CH2)nNH2, wherein n is 2 or 3 and R is a lower alkyl radical of not more than 4 carbon atoms.
