Close Encounters of the Third ‘Crude-Oil’ Kind

This paper compares and contrasts the accelerated laboratory autoclave (NACE TM0185) performance at 300°F (149°C), and 250 psig, of eight polycyclamine cured epoxy linings. The latter were tested for tank, vessel and pipe spool applications in the oil and gas industry. Five of the linings were commercially available and three were experimental. A modified amine cured epoxy was also evaluated in the study, a lining used to transport shale oil in railcars at temperatures up to 200°F (93°C).

A modified amine cured epoxy was also evaluated in the study, a lining used to transport shale oil in railcars at temperatures up to 200°F (93°C). The hydrocarbon media employed in the testing was neither conventional nor unconventional crude, but rather the third “crude oil” kind, namely shale oil and it was obtained from the Bakken shale play. Electrochemical Impedance Spectroscopy, immersion and adhesion testing, and visual inspection were used to evaluate the high temperature resistance, barrier properties and adhesion to carbon steel panels of two-coat thin film epoxy systems, and single coat, solvent free epoxy lining systems. A case history is provided for a single coat epoxy lining used for transporting shale oil in railcars.
