Project Installation Overview
Injection of the corrosion inhibitor compounds was initiated and completed.

The corrosion inhibitor solution mixture of FVS and FAN-5 were split equally between two large tanks filled with potable water and slowly mixed into the tanks untill dissolved completely.

About 93.75% of this corrosion inhibiting solution mixture was injected into Pipeline “A” (12” dia.) at three seperate locations, and the remaining ~6.25% was injected into Pipeline “B” (6” dia.). There were a total of 3 injection points along the 12” line, and a single injection along the 6” line.

The 12” line received ~68.75% of the solution mixture at injection point 1 (high side inside the terminal), ~6.25% of the solution mixture at point 2 (high side inside the terminal but short ~20-ft section), and ~18.75% of the solution mixture at point 3 (outside of main terminal fence). The 6” line received ~6.25% of the solution mixture at a single high side injection point outside of the main terminal fence. All injections were completed successfully.
