Dispersion of Waxy Gas Oil by Some Nonionic Surfactants

ABSTRACT
Straight chain fatty alcohols having the following number of
carbon atoms C12, C14, C18 and C21 each alcohol was ethoxylated to the
same of ethylene oxide content, characterized through average molecular
weight and elemental analysis. The surface properties of these
compounds were studied through surface tension measurements. The
synthesized additives were tested as flow improvers for improving the
cold flow properties of two waxy gas oils through pour point test. The
results show the right efficiency of these compounds in improving the
flowability. Comparative evaluation of the synthesized products with
available commercial additive (com) showed their efficiency and
suitability to use in gas oils. Wax modification was assisted through
photoanalysis. Correlation between wax modification and flow
improvement in term of pour point depression appeared to be merely
qualitative in such heterogeneous gas oil systems.
