Application of Hypochlorous Acid (HOCI) for Biofouling Control, MIC Mitigation, and Operational Sustainability in Oil, Gas, and Petrochemical Industries

Microbiologically Influenced Corrosion (MIC) and biofouling represent pervasive, multi-billion-dollar annual challenges for the global energy sector, impacting infrastructure integrity, operational efficiency, and safety. Traditional chemical biocides, while effective, face increasing regulatory, environmental, and resistance-related challenges. This paper examines the application of Hypochlorous Acid (HOCI) as a disruptive, sustainable biocide for the oil, gas, and petrochemical industries. HOCI, a weak acid and a potent naturally occurring oxidant produced by mammalian immune systems, offers a compelling alternative due to its broad-spectrum antimicrobial efficacy, rapid action, and favorable environmental profile. We review the fundamental mechanisms of MIC, delineate the electrochemically generated HOCI's chemistry and mode of action against biofilm consortia, and present a comprehensive analysis of its industrial applications, including produced water reinjection, pipeline cleaning, and cooling tower treatment. The discussion addresses scalability, integration challenges, and compatibility with existing systems. Finally, we evaluate HOCI's alignment with Health, Safety, Environmental (HSE), and Environmental, Social, and Governance (ESG) principles, concluding that electrochemical generation of HOCI presents a robust, sustainable pathway for enhancing operational sustainability and asset longevity in the energy sector.
