Studying the Interaction between a New Mixture in Enhancing Drag Reduction Efficiency

Polymers are used as drag reducer in a strategic pipeline successfully for the past few decades due to its
viscoelastic properties that can suppress the turbulent in
pipelines. One of the many issues facing the use of these
additives is its resistance to high shear forces during the
transportation where it can be easily degraded where they pass them a pump. In the present work, polymer-surfactant
complexes of anionic polymer and nonionic surfactant are
investigated to prove its capability in enhancing the drag
reduction and mechanism degradation performance. The
interaction between anionic polymer Poly (acrylamide-codiallyl-dimethylammonium chloride) and nonionic surfactant
tween 20 in aqueous solution has been studied by using
rheology, rotating disk apparatus (RDA) and pipe loop
techniques. The effect of polymer concentration, surfactant
concentration and rotational speed in enhancing the drag
reduction were studied. The results showed that almost 35%
drag reduction can be obtained. In addition, the effect of the degradation on the mixtures as a function in the time has been discussed also.
