Synthesis, Characterization of Borax Crosslinked Guar Gum Hydrogel and its Effect in Treatment of Crude Oil Emulsified Water

Nonionic nature of guar gum provides an acceptable material for modification, guar gum based hydrogel were synthesized by crosslinking purified guar gum with borax disodium tetraborate, decahydrate at different percentage. Estimation of crosslinked borax has carried out titrimetrically and occurrence of the reaction was confirmed using FT IR spectroscopy, elemental analysis, thermal analysis, scanning electron microscopy and rheologically. To examine reverse demulsification efficiency of different grades of hydrogel, a crude oil in water emulsion sample was studied by a modified jar test method. The efficiency of the test materials was compared with the Industrial Reverse Demulsifier IRD . The best grades of hydrogel didn't outperformed industrial reverse demulsifier but at low concentration GCB6 diluted to about 0.3 in a dose of 50ppm a maximum efficiency of 66 was reached. The single step synthesized green product thus exhibited a potential as reverse demulsification agent which can be developed. Ayman Abu Reid | Yousif. A. Ragab | Salih. MAA | Imad. E. A.
