Trans-Alaska Pipeline (TAPS) has initiated a large-scale corrosion mitigation program using chemical inhibitors. Ultrasonic inspection in 1988 revealed internal corrosion predominantly in low-velocity piping where emulsified water had precipitated out of the crude oil and supported microbial corrosion. TAPS developed a system of manual batch treatment to treat the numerous dead legs in the pump-station facilities along with procedures for monitoring inhibitor effectiveness. This inhibitor treatment system was implemented in 1990 at TAPS's stations. This article is about the program focuses on the corrosion sites and project design. The conclusion deals with treatment and monitoring procedures and presents some preliminary results.
