Wax Control by Designing Polymeric Pour Point Depressant Additives for Indian Crude Oil

摘要

This study details improvement of flow property of oil by seven different poly(n-cinnamates-co-N-hexadecylmaleimide) synthesized using cinnamic acid, maleic anhydride, and hexadecylamine and their characterization as performed by infrared (IR), 1H-NMR and 13C-NMR spectroscopy, and gel permeation chromatography (GPC). An AR-500 rheometer was used to evaluate the effect of additives on rheology of oil at different temperatures and different concentration of additives. Cn-22 is the most effective depressant, and reduces the pour point of Dahej oil containing 29.09 wt.% waxes from 35°C to 2°C at 1000 ppm concentration.View full textDownload full textKeywordsAlkyl cinnamates, AR-500 rheometer, cold finger test, pour point, pour point depressant additives, viscosity, yield stressRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01932691003656896
