Abstract
This study aims to produce cost-effective pour point depressant (PPD) to mitigate wax deposition of waxy petroleum crude oil (WPCO) in subsea pipelines from free fatty acids which are produced as wastes from sunflower oil refining process. The major constituents of these wastes are unsaturated fatty acids i.e., oleic acid (41.926%) and linoleic acid (38.892%), were first esterified and copolymerized with maleic anhydride. Then the obtained copolymers were then esterified with fatty alcohol (C19H36O3) to form comb-like poly fatty esters (PFES). The copolymers and its esterified form were structurally characterized by FTIR, XRD spectral analysis and scanning electron microscopy(SEM). Moreover, the potential effects of this PPD on paraffinic waxes, pour point, and waxes crystallization was investigated by (DSC) and (XRD). The measurements exhibited that using of this PPD has great impacts on hindering wax formation and on the WPCO pour point reduction from 24 to 3ºC by using a dosage of 3000 ppm.
