Abstract

The graft copolymerization of acrylic acid AA initiated by potassium persulfate PPS progresses through free radical initiation mechanism carried out onto purified guar gum backbone and acrylamide AM which has been synthesized by grafting polyacrylamide chains onto carboxymethyl guar gum CMG backbone using conventional redox grafting. The graft copolymers were characterized using FT IR spectroscopy, elemental analysis, thermal analysis, scanning electron microscopy and rheologically. Reverse demulsification performance of the graft copolymers were evaluated using crude oil in water emulsion sample by a modified jar test method. It showed that graft copolymers based on acrylamide were better reverse demulsifiers than those based on acrylic acid. Among acrylamide synthetic graft copolymers CMG g AM CGA1 diluted to about 1 in a dose of 50ppm performed best when compared with the other synthetic graft copolymers of acrylamide with a reverse demulsification efficiency of 64.7 , while the best reverse demulsification efficiency for graft copolymers of acrylic acid GG g AA GGA2 diluted to about 1 in a dose of 50ppm is 59.2 , both products didn't outperformed the Industrial Reverse Demulsifier IRD .
