The present invention relates to crude oil processing, particularly related to conversion of crude oil containing high amount of naphthenic acid compounds to lighter hydrocarbon materials with minimum capital expenditure. The invented process utilizes a novel scheme for high TAN crude oils by employing thermal cracking process to maximize the residue conversion to valuable products, which require minimum modifications in unit metallurgies and corrosion inhibitor injection schemes in refineries.
