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 to prevent and/or reduce fouling of crude oil refinery equipment. The method includes adding an effective amount of a high molecular weight naphthenic tetra-acid to the base crude oil to form a crude oil mixture and feeding the crude oil mixture to a crude oil refinery component. Particularly, the high molecular weight naphthenic tetra- acids include ARN acids.
