FIELD: oil treating. SUBSTANCE: separation is facilitated by using ester- based substances to provide complete separation of water and minimization of salt content. In particular, demulsifiers are used being products of esterification of oxyalkylated primary fatty amine and 0.5-1.5 mol per 1 mol of amine of monomeric dicarboxylic acid or dimeric fatty dicarboxylic acid.
