Title:

METHOD FOR INHIBITING CORROSION USING PHOSPHOROUS ACID

Document Type and Number:

WIPO Patent Application WO2003006580

Kind Code:

A3

Abstract:

The present invention relates to a method for inhibiting high temperature of corrosion-prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of phosphorous acid, typically up to 1000 wppm, to the metal surface.
