Abstract
Paraffin deposition remains a persistent challenge in the petroleum industry, particularly exacerbated in cold environments, necessitating effective mitigation strategies. Among these, pour point depressants (PPDs) stand out as a superior method. Nanomaterials have advantage of their surface properties due to which they are extensively used in petroleum industry. The present study is aimed at synthesizing a nanohybrid polymer tailored for use as a flow improver for Indian crude oil. The synthesized product was characterized by different analytical techniques and evaluated by pour point studies, rheological studies, Cold finger test, microscopic studies and aging studies. Results underscored the substantial potential of the PPD in reducing both pour point and viscosity of the crude oil. Significantly, the most notable achievement was observed at a concentration of 3000 ppm, yielding a remarkable pour point reduction of 18 °C alongside a substantial 95% decrease in viscosity. Microscopic analyses unveiled the presence of dispersed wax crystals after treatment with the nanohybrid polymer, indicative of its interaction with paraffin crystals, thereby impeding their formation or growth. Furthermore, aging studies elucidated the stability and sustained efficacy of nanohybrid polymer over time, crucial considerations for its practical applicability within the Petroleum industry. Overall, this investigation underscores the promising role of nanohybrid polymers as effective pour point depressants, offering tangible solutions to the persistent challenge of paraffin deposition while enhancing operational efficiencies and cost-effectiveness within the industry.
