TREATMENT OF CRUDE OILS USING SULPHATE-REDUCING BACTERIA H2S FORMATIONS
|
Abstract:
In the aerobic condition, the structure of crude oils were changed by hydrocarbon-oxidizing bacteria. The structure of crude oils was also changed by sulphate-reducing bacteria in the anaerobic condition. Sulphate-reducing bacteria can make use of crude oils as sole carbon source. After treatment of crude oils, the sample was analyzed with gas chromatograph(GC).The result of GC show the lighter compounds of crude oils decrease, but the more high weight compounds increase. The sulfate-reducing bacteria were detected in the oilfield water of Tarim basin. Its numbers were up to 10~(4) cells/ml. The results support the view that H_(2)S is the origin of biology.
