Ferrous metal corrosion

They also provide useful corrosion inhibition by the adsorption of calcium phosphonate onto iron oxide corrosion products, thus reducing the ferrous metal corrosion rate. Phosphonates can be described as cathanodic corrosion inhibitors. [Pg.448]

Corrosion inhibitor Two inhibitors could be used a. Copper corrosion inhibitor to help prevent sulfur, hydrogen sulfide, and mercaptan attack on copper b. Ferrous metal corrosion inhibitor to prevent water/oxygen initiated corrosion of iron and steel system components... [Pg.45]

Vast amounts of information have been written about ferrous metal corrosion and corrosion mechanisms. For the purpose of this discussion, only a brief review of corrosion chemistry and corrosion process will be presented. [Pg.152]

The process of ferrous metal corrosion is demonstrated in FIGURE 6-12. [Pg.154]

Ferrous metal corrosion can occur quite readily whenever a difference in electrical potential exists between iron and a corroding agent. Corrosion begins whenever electrons leave the iron surface at the anode and ferrous ions form ... [Pg.154]

Although uncommon in most fuel systems, ferrous metal corrosion initiated by hydrogen sulfide can occur. In the presence of water, hydrogen sulfide can react with iron to form iron sulfide ... [Pg.155]

Although no ASTM ferrous metal corrosion specification exists now for gasoline, diesel fuel, and other fuels, many refiners and marketers have adopted the National Association of Corrosion Engineers (NACE) Corrosion Standard Method TM-01-72-93 as a specification. This method has also been utilized by most product pipeline companies and is an established requirement. The NACE corrosion method is summarized as follows ... [Pg.182]

During the processing of fuels, acids such as sulfuric acid and hydrofluoric acid are used. Sulfuric acid can be used to polymerize fuel olefins and remove components from fuel such as mercaptans and thiophenes. Sulfuric and hydrofluoric acids are used in the alkylation process to produce high-octane, branched paraffins. Carryover of these acids into fuel can initiate ferrous metal corrosion. [Pg.209]

Add a ferrous metal corrosion inhibitor to the fuel at a maintenance dosage of 5 to 10 ppm. [Pg.209]
