The deposition of paraffin wax from crude oil at low temperatures due to wax
deposition, high pour point, high viscosity, and weak flow capability is
among the critical and persisting challenges faced by the petroleum
industry. In this study, a new para-decyloxy allyl benzoate (I10) was
prepared, polymerized into HI10, and copolymerized with dioctadecyl maleate
into MHI10 via the free-radical polymerization method employing
azobisisobutyronitrile and toluene as the initiator and solvent,
respectively. The prepared monomer was characterized by spectroscopic
analyses (Fourier-transform infrared (FT-IR)) and proton nuclear magnetic
resonance. Further, the polymers were characterized by FT-IR, and their
average molecular weights were determined by gel permeation chromatography.
The prepared compounds were taken in different concentrations and then
tested as flow improvers of Qarun waxy crude oil using pour point depression
and rheological parameters. The results of this test indicated that MHI10
exerted the highest effect on pour point reduction and the rheological
parameters (yield value and apparent viscosity). Moreover, an increase in
the efficiency of the additives was observed after increasing their
concentration from 1000 to 5000 ppm.
