A number of inhibition treatments were tested using these pit specimens, including substitution of chloride-containing water with demineralized water, sodium hydroxide dosing, and molybdate dosing. Corrosion was monitored...

...P. Ajmera; W. Robbins; S. Richter; S. Nešić Asphaltenes (heptane insolubles) from a variety of crude oils have been identified previously as contributors to inhibition of internal corrosion of mild steel pipelines. However, the mechanism of inhibition is unknown. To explore the mechanism, carbon...
