Article Synopsis
- The study investigates the effects of turbulent flow on a 400 ppm solution of guar gum, focusing on how molecular degradation impacts drag reduction.
- Analysis techniques like spectroscopy and viscosimetry reveal that the drag reduction benefits diminish as the guar gum breaks down, mainly due to hydrolysis of its glycosidic bonds.
- Results also indicate that this degradation reduces the thermal stability of the polysaccharide, providing insights necessary for developing more efficient biopolymers to enhance drag reduction.
Guar gum is used in low concentrations as a drag reducing agent in turbulent flows to significantly accelerate flow in oil pipelines, oil well operations and aqueous systems. Drag reduction also promotes a decrease in energy demand in pumping systems. However, the polymers undergo mechanical degradation and lose the ability to promote drag reduction over time.
