Abstract
- Microbiologically influenced corrosion (MIC) is one of the major corrosion threats in the oil and gas industry. It is caused by environmental biofilms. Glutaraldehyde is a popular green biocide for mitigating biofilms and MIC. This work investigated the efficacy of glutaraldehyde enhancement by food-grade green chemical d-limonene in the biofilm prevention and MIC mitigation using a mixed-culture oilfield biofilm consortium. After 7 days of incubation at 37 °C in enriched artificial seawater in 125 mL anaerobic vials, the 100 ppm (w/w) glutaraldehyde + 200 ppm d-limonene combination treatment reduced the sessile cell counts on C1018 carbon steel coupons by 2.1−log, 1.7−log, and 2.3−log for sulfate reducing bacteria, acid producing bacteria, and general heterotrophic bacteria, respectively in comparison with the untreated control. The treatment achieved 68% weight loss reduction and 78% pit depth reduction. The 100 ppm glutaraldehyde + 200 ppm d-limonene combination treatment was found more effective in biofilm prevention and MIC mitigation than glutaraldehyde and d-limonene used individually. Electrochemical tests corroborated weight loss and pit depth data trends. [ABSTRACT FROM AUTHOR]
