Abstract: Metal naphthenate is removed from a crude hydrocarbon mixture by a process. The process includes mixing the crude hydrocarbon mixture comprising metal naphthenate with an acid in the presence of water, wherein the acid converts the metal naphthenate to naphthenic acid and metal salt; allowing the metal salt to partition into a water phase; and separating the crude heavy hydrocarbon mixture comprising naphthenic acid and the water phase comprising the metal salt.

Abstract: A process for the preparation of at least one ARN acid or salt thereof comprising: (I) allowing at least one ARN acid salt to form during the production of crude oil in the presence of water; (II) removing at least 5 wt % of the formed at least one ARN acid salt, e.g. from the oil water interface; and optionally (III) converting said salt into an acid.
