Abstract

The present invention relates to development of high performing oil soluble and water dispersible corrosion inhibitor composition for mitigating internal corrosion of crude oil pipelines during storage and transportation of crude oils. The developed composition consists of acid-amine complex as corrosion inhibiting agent, mixture of organic acids as dispersing agent and ester derivative of alkylated phenol for better film formation. The present invention further relates to a process of preparation of the oil soluble and water dispersible corrosion inhibitor composition and subsequently a process for protecting the corrosion of internal metal surface of crude oil transportation pipelines using the corrosion inhibitor composition.
