High-Temperature, High-Pressure Oxidation Of Alloys Caused by Carbon Dioxide

Abstract

Presents data on corrosion of heat resistant alloys by high pressure carbon dioxide. Describes oxidation behavior of 26 alloys in 1000 to 2000 psi carbon dioxide in temperature range of 1100 to 1740 F. Oxidation rates of heat resistant alloys in 2000-psi carbon dioxide at 1300 and 1500 F were very low. In all cases, scales were protective. Oxidation followed a parabolic or slower rate law. At 1740 F, most alloys tested exhibited excessive scaling in 1000-psi carbon dioxide. 3.4.6
