Studies on the Influence of Cationic Surfactant Chemical Additives on Wax Deposition

Wax deposition studies were carried out to investigate the modification of wax crystals when gas oil was doped with some polymeric surfactant chemical additives. These additives were synthesized via esterification of chloroacetic acid and different alcohols to corresponding esters that were quaternized with polytriethanol amine and polyvinylpyridine to give polycationic surfactants. The surface activities of these polymers were evaluated using standard methods. Properties such as pour point depression data and average carbon number were studied. The behavior of the mixtures of the prepared surfactants on the depression of pour point was determined. The results given indicated that these additives are good surfactants and low temperature improvers for gas oil.
