ADDITION OF HIGH MOLECULAR WEIGHT NAPHTHENIC TETRA-ACIDS TO CRUDE OILS TO REDUCE WHOLE CRUDE OIL FOULING

摘要

High molecular weight naphthenic tetra-acids are added to a base crude oil toprevent and/or reduce fouling ofcrude oil refinery equipment. The method includes adding an effective amountof a high molecular weight naphthenic tetra-acid tothe base crude oil to form a crude oil mixture and feeding the crude oilmixture to a crude oil refinery component. Particularly, thehigh molecular weight naphthenic tetra- acids include ARN acids.
