Scientists have effectively reduced corrosion in crude oil and petroleum pipelines using natural and non-toxic biocides to replace imported and toxic versions.
A biocide is defined in the European legislation as a chemical substance or microorganism intended to destroy, deter, render harmless, or exert a controlling effect on any harmful organism by chemical or biological means.
Until now, it is estimated that the Nigerian oil and gas industry loses up to $765 million yearly to corrosion of oil pipelines.
Professor of Petroleum Microbiology and Microbial Biotechnology, Federal University, Ndufu-Alike, Ikwo (FUNAI) Ebonyi State, Dr. Chuma Conlette Okoro, and his team of researchers published their latest work in the journal Corrosion Science.
The other researchers include: Olusegun Samuel of the Department of Marine Biology, University of Lagos; and Johnson Linc of the School of Life Sciences, University of KwaZulu Natal Westville campus, Durban, South Africa.
The researchers led by Okoro investigated the effects of some biocides on methanogens associated with pipeline corrosions.
