Wax inhibitor performance comparison for waxy crude oil from Fang oilfield

In petroleum chemistry, waxy oil from paraffins can cause operating problems for production. The chemical method is used to remove by using chemicals or additives prevent the wax problem. this study, performance of inhibitor are evaluated measurement pour-point reduction and deposition crude Mae Soon area, Fang oilfield. Wax determined cold finger technique. inhibitors, hexane, Poly(maleic anhydride-alt-1-octadecene) (PMAO) monoethanolamine (MEA) mixed in sample at various concentrations. From experiment, it presented that hexane reduce temperature up 19.55 % deposit 92.56 %. Moreover, MEA PMAO have less effect on reduction. However, they high efficiency deposition. provide better than MEA. amount lower same conditions. percentage 39.19 83.02 58.54 88.51 PMAO. Furthermore, results, preferred concentration be 10 7500 ppm low 5000 higher temperature. results research applied practical way prevention operation area oilfield problem future.
