Abstract
A method for the prevention of fouling in a distillation train of a hydrocarbon processing unit. The method involves the precipitation of foulants contained in the hydrocarbon fluid prior to distillation. Precipitation of fouling components occurs when the liquid to be distilled is contacted with a high boiling fluid which is a non-solvent for the foulant causing species but is a solvent for the liquid that is to be distilled.
