Carboxymethyl cellulose from cavendish banana peel as a drag reduction agent
Reducing drag is reducing frictional pressure loss under turbulent flow conditions and can be achieved with addition of additives. These additives such as small amount of polymer can dramatically affect the turbulent structures of the flowing fluid and increase the flow rate. Synthetic polymers which are widely employed harm our environment when used excessively. A biopolymer is then soughed for such purpose which is produced by living organisms and they are fairly shear stable and biodegradable. A biopolymer, derived from the Cavendish banana peel, was synthesized in this study. The polymer was converted to carboxymethylcellulose by etherification process. The drag reduction was assessed in this study using a rheometer where a reduced produced torque was perceived as a reduction of drag. The biopolymers produced were then rheologically characterized where the viscoelastic effects produced by these biopolymers were utilized to explain the drag reduction phenomena. The findings shows that the biopolymer, synthesized at the right conditions, is capable of drag reduction up to 40 demonstrating the potential of the biopolymer from the green Cavendish banana peel at drag reduction when dissolved in water. The biopolymer synthesized at reaction temperature of 50°C and NaOH concentration of 40 works best at drag reduction. © Published under licence by IOP Publishing Ltd.
