    The carbon dioxide content is often not very high in refinery streams, except in hydrogen reformer plant systems. In addition, one of the major sources of corrosion on carbon steel vessels in sweetening units is heat stable material, which is a product of amine degradation (Rooney and Dupart, 2000). Oxygen plays a major role in amine degradation—the reaction of oxygen and the amine produces organic

  • The Effects of Carbonic Acid on Steel It Still Runs

    Carbonic acid (H2CO3) is a common inorganic compound formed when carbon dioxide (CO2) dissolves in water (H2O). In aqueous solution, a small portion of carbonic acid will further dissociate to form H+ and bicarbonate (HCO3) ions. The resultant weak acid can corrode, rust or pit steel but the extent

  • Carbonic Acid Corrosion of Steel CORROSION

    Abstract. The relation between the corrosion rate of steel in carbonic acid and the CO 2 partial pressure was determined by means of weight loss and polarization resistance measurements. This relation is compared with that expected for completely dissociated acids, and appears to be significantly different.
