High levels of Black Powder contamination was in the glycol system, with particulate too small for a Y-Strainer filter screen to remove. The Black Powder contaminant resulted from a moisture catalyst, corroding the pipeline walls resulting in fine abrasive particles of iron sulfides and oxides reducing the life of glycol and wearing on the circulation pumps and components.
Alex Priori of Renox suggest installing a BPS Magnetic Y- Separator on six pumps as a test to remove the Black Powder to sub-micron levels.
A significant amount of Black Powder was removed from the glycol system. Since installing the BPS Magnetic Separators in 2008 the pumps have operated without failure with full efficiency.
