Stability of light straight run diesel fuel during long term underground storage in small size steel tanks
- Israel Institute for Biological Research, Ness-Ziona (Israel)
Three batches of Light Straight Run Diesel Fuel (LSRDF), dyed by a green marker, were stored for five years in precleaned 50,OOOL, steel, cylindrical, underground storage tanks, with or without biocide and a stabilizer additives package. During this period, the fuels were kept dormant and no draining operations were performed. A close follow up on the chemical properties, biocide content and the level of microbial contamination, in the stored fuels, was done throughout the storage experiment. The chemical properties of the untreated fuel remained unchanged but the microbial contamination in {open_quotes}bottom-bottom{close_quotes} samples gradually increased during the first year and remained high for the next four years. In contrast, no microbial activity was found in the treated fuel tanks. However, in the fuel treated only by biocide, the dye green marker gradually diminished while {open_quotes}acidic{close_quotes} odor emitted, however the fuel stayed within chemical specifications range. Fuel treated with stabilizer additives package kept its chemical properties unchanged for the five years storage. The results indicated that untreated LSRDF can be stored for at least five years without any significant microbial or chemical damage, provided good starting condition and no turnover taken place. The biocide treated effectively hindered microbial activity but enhanced a slight oxidation activity in the fuel. Stabilizer additive addition prevented this minor oxidation, while keeping the fuel and the storage tank free from microbial contamination.
