Pour Point Depressant

The waxes present in most crude oils include n-alkanes, iso-alkanes, alkyl cyclic compounds and alkyl aromatics. In most crude n-Alkanes are the predominant species. The amount and distribution of these n-Alkanes is crude specific. Short-branched chains are the next most common. These have a significant impact on wax deposition characteristics.
The wax appearance temperature (WAT) is the temperature at which, on a cooling cycle, the crude oil first precipitates solid wax. This is arguably the single most important characteristic in examining wax deposition potential in crude oil. The deposition of wax leads to several problems in reduced production and impaired flow assurance. Severe deposition can lead to loss of production and pipeline blockage etc.
