Sludge formation in storage of diesel oil with additive


  1. 1.

    During prolonged storage of DS-11 oil with 5% TsIATIM-339 additive, sludge accumulates on the tank bottoms; this sludge is an emulsion of water and oil, stabilized by the surface-active components of TsIATIM-339, including the stable free radicals present in the additive.

  2. 2.

    The emulsion sludges consist of 90–99% oil, 1.4–5.5% solid component, and 0.8–8.6% water. The solid component consists of 75–83% ash elements, including 31–54% barium. The number of paramagnetic particles per gram of solid component of the sludge may vary from 3 · 1017 to 6 · 1018.

  3. 3.

    Oil losses during long-term storage due to sludge formation may amount to 0.03–0.08% in aboveground tanks and 0.18–0.19% in trench tanks, which exceeds the established standard by a factor of 5–10.
