Abstract
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--(CH.sub.2)nNH.sub.2, wherein n is 2 or 3 and R is a lower alkyl radical of not more than 4 carbon atoms.

A process for controlling corrosion in water-free petroleum and petrochemical hydrocarbon processing system separation units consisting essentially of adding a corrosion inhibiting amount of a composition having the formula R--O--(CH.sub.2)nNH.sub.2 wherein n is 2 or 3 and R is a lower aklyl radical of not more than 4 carbon atoms to the hydrocarbon being processed in the separation unit.
A process for controlling corrosion in water-free petroleum and petrochemical hydrocarbon processing system separation units consisting essentially of adding to the hydrocarbon a corrosion inhibiting amount of a film-forming amine along with a composition having the formula R--O--(CH.sub.2)nNH.sub.2 wherein n is 2 or 3 and R is a lower alkyl radical of not more than 4 carbon atoms in an amount sufficient to raise the pH of the initial condensate to above 4.0.
