Development of a Test Kit to Evaluate Biocide Efficacy in Limiting Microbiologically Influenced Corrosion

Microbially influenced corrosion (MIC) accounts for about 40% of internal corrosion in gas transmission pipelines, contributing to an estimated annual cost of $7 billion. MIC poses significant risks, leading to productivity loss, increased downtime, environmental damage, and personnel injury. Identifying MIC presents a challenge due to the complex relationship between microorganisms and corrosion, as multiple factors influence corrosion, and different mechanisms can result in similar corrosion patterns. Current techniques often lack the ability to differentiate between microbial and other forms of corrosion, requiring highly technical expertise and often providing delayed detection. To address these challenges, Corrolytics has developed a test kit aimed at monitoring microbial corrosion and evaluating the efficacy of biocides and chemical treatments. The test kit fills a crucial knowledge gap for asset integrity managers and corrosion engineers, providing faster, more accurate detection of MIC. Through partnerships with industry leaders and successful validation with real-world samples, Corrolytics has demonstrated the effectiveness of its technology. With the support of PHMSA funding, Corrolytics aims to further refine its test kit to evaluate biocide efficacy, paving the way for enhanced corrosion monitoring and control in pipelines, ultimately reducing downtime, environmental damage, and operational costs.
