Midstream Operator – Coyanosa Texas, Dec 2021 – Problem – Black Powder contamination under 5 microns in size was causing costly filter change-outs and reduced efficiency of the Amine system to remove H2S and Co2.
High concentrations of Black Powder contamination in the glycol system composed of particles too small for a y-strainer filter screen to remove. This corrosion resulted in abrasive iron sulfides and iron oxides reducing the life of the glycol…
The contamination would degrade new glycol and reduce it’s ability to cool and remove moisture from gas. Corrosion of the carbon steel piping would cause contamination build-up during transmission and storage…
