Corrosion Inhibition Studies of Synthesized Oleic Sources-Based Green Inhibitors From Agro-Industrial Waste

Abstract

Now, the use of corrosion inhibitors is an effective method to mitigate the corrosion in hydrocarbon extraction and transportation pipelines. Crude oil has several corrosive species, which includes chloride, carbon dioxide, and hydrogen sulphide. Organic type corrosion inhibitors are frequently used to prevent the metallic surface's corrosion due to the mechanism of adsorption related to the displacement of water molecules and the formation a monomolecular hydrophobic layer. With the aim of increasing the inhibition efficiency and obtaining a sustainable corrosion inhibitor, vegetables oils are extracted from agro-industrial waste such as rice, coffee, palm, avocado, etc., and have been used to synthesize a new generation of inhibitors, namely, green corrosion inhibitors, which are cheaper and environmentally friendly. Hence, the purpose of this chapter is to explain the concepts and fundaments about corrosion inhibitors based on imidazoline derivates of natural oils and include information on synthesis and electrochemical performance of a green corrosion inhibitor.
