  • COMPOUNDS AND METHODS FOR INHIBITING CORROSION IN HYDROCARBON PROCESSING UNITS
    Publication number: 20150114884
    Abstract: Treatment compositions for neutralizing acidic species and reducing hydrochloride and amine salts in a fluid hydrocarbon stream are disclosed. The treatment compositions may comprise at least one amine with a salt precipitation potential index of equal to or less than about 1.0. Methods for neutralizing acidic species and reducing deposits of hydrochloride and amine salts in a hydrocarbon refining process are also disclosed. The methods may comprise providing a fluid hydrocarbon stream and adding a treatment composition to the fluid hydrocarbon stream. The treatment compositions used may have a salt precipitation potential index of equal to or less than about 1.0 and comprise either water-soluble or oil-soluble amines.

  • CORROSION INHIBITOR COMPOSITIONS, METHODS FOR MAKING AND METHODS FOR USING
    Publication number: 20130302210
    Abstract: A method for inhibiting corrosion on metallic surfaces in contact with a liquid hydrocarbon media is provided. A corrosion inhibitor composition is dispersed into a liquid hydrocarbon media to form a protective film on the metallic surfaces. The corrosion inhibitor includes a polyamic acid having structure I: A-HN—(CH2)2—[—NH(CH2)2—]x—NH-A??I or structure II: A-HN—(CH2)3—[—O—(CH2)2—]n—O—(CH2)3—NH-A??II wherein A has structure III: R—CH?CH—CH(CO2H)—CH2C(O)—??III and R is a (C8-C22) alkyl group or a (C8-C22) alkenyl group, x is an integer from 0 to 6 and n is an integer from 1 to 6. A method for preparing the corrosion inhibitor is also provided.
