Screening and evaluation of microbiologically influenced corrosion (MIC) in seawater and effluent water injection systems in Kuwait
- Kuwait Inst. for Scientific Research, Safat (Kuwait). Petroleum, Petrochemicals and Materials Div.
Injection water sources in Kuwait range from brackish water (TDS=4000 mg/l) through seawater (TDS = 30,000 mg/l) to high saline brines (TDS = 200,000 mg/l). Some of these water sources are highly sulfide sour and may require treatment to prevent scaling, corrosion or iron sulfide precipitation. Another particular problem in water injection systems is the uncontrolled growth of sulfate-reducing bacteria (SRB) which leads to increased corrosion of the process plant. Therefore, evaluation schemes were undertaken to study the relative risks of MIC in a range of Kuwait`s water sources, using a combination of field sampling and laboratory biofouling trials. Recirculating biofouling loops were set up with the appropriate site water, and inoculated with the bacteria from the system so that an active biofilm was set up on small studs. These biofouled studs were treated with proprietary biocide inhibitors under various dose rates in order to select the most appropriate control regime for particular water chemistries and process options.
