Selection of corrosion inhibitors to control microbiologically influenced corrosion
- Champion Technologies, Inc., Fresno, TX (United States)
Microbiologically Influenced Corrosion (MIC) is a serious problem. The establishment of a biofilm on a metal surface plays a critical role in MIC. Quaternary amines have been reported to inhibit the bacterial adhesion to the metal surface. However, most of the quaternary amines are quite toxic. In light of growing concerns of environmental impact and safety, a series of experiments was conducted to evaluate various corrosion inhibitors for their inhibition capability of bacterial adhesion as well as bacterial kill. The results indicate that some inhibitors are capable of inhibiting biofilm formation on mild steel coupons. In addition, these inhibitors have biocidal properties. Initial toxicity studies suggest that some of these inhibitors are less toxic than most industrial biocides. This paper discusses the cost-effectiveness of use of these inhibitors in some systems.
