Microbial problems have occurred when storing jet fuel underground in unlined rock caverns with a fluctuating waterbed. These problems have mainly been concerned with accumulation of corrosive compounds in the fuel. They have been found to be a result of the production of hydrogen sulphide by anaerobic sulphate-reducing bacteria (SRB) in the waterbed and bottom sediment of the caverns. To study the main factors governing the rate with which jet fuel became corrosive, laboratory models were used that simulated the conditions in rock caverns. It was found that there was an interaction between the aerobic hydrocarbon degrading organisms and the SRB for the production of hydrogen sulphide. The leakage rate of groundwater into the system was important and an increased rate resulted in increased oxygen and sulphate consumption. The concentrations of sulphate and oxygen in the bedwater and leakage water were also important for the rate of development of corrosive fuel. The amount of sediment had a marked effect on the time it took for the fuel to become corrosive. The effect of temperature was also studied. |
