In the search for a “chemical mummy” in the Canadian oil patch, this paper outlines discoveries made from forensic work to unravel epoxy lining failures in several water treatment WAC (Weak Acid Cation) vessels.

The “dig” exhumed third party independent testing of several linings at elevated temperatures in chemical immersion, scrutiny of the epoxy lining chemistry and application processes, and compared the severity of real world service exposures inside a WAC vessel with accelerated laboratory testing chosen to simulate WAC service conditions.
