During long-term storage of petroleum products in rock caverns jet fuel has in a couple of cases become corrosive due to sulfate-reducing bacteria producing hydrogen sulfide in the bedwater. In order to monitor corrosivity of petroleum products a method has been developed based on using piezoelectric crystals (20 MHz) with silver electrodes. The method has been found to be more sensitive, when measuring silver corrosivity, than the standard silver strip test IP 227/73. The method has been evaluated and used to monitor the corrosivity of jet fuel stored in rock caverns. It has also been possible to study the interactions between different corrosive compounds in jet fuel using this method.
