Studies On African Oil Bean Plant As A Corrosion Inhibitor For Low Carbon Steel In Crude Oil:- Onuchukwu David C

ABSTRACT

 This research work was performed on five distinct parts of the African oil bean plant (leaves, pods, seed shells, bark and root) and involved extraction, corrosion inhibition test of low carbon steel in crude oil utilizing gravimetric analyses. The sample morphology was evaluated. 1 he rate of corrosion of low carbon steel specimens in the plant extract was observed to decrease with immersion time (120hrs-792hrs) and increase in the concentration of extracts by increasing their ratio with respect to the medium. The inhibitors inhibitory efficiency (IE) increased with lime (120hrs-792hrs) demonstrating a physisorption of extracts on the carbon steel surface. Ail the parts of the plant showed good inhibition efficiency in the medium ranging from 82.11% to 99.02% but the pod was the best with an inhibitory efficiency of 99.02%. .
