Enhancing the Drag Reduction Phenomenon within a Rotating Disk Apparatus Using Polymer-Surfactant Additives

Abstract

Pipelines and tubes play important roles in transporting economic liquids, such as water, petroleum derivatives, and crude oil. However, turbulence reduces the initial flow rate at which liquids are pumped, thereby making liquid transportation through pipelines inefficient. This study focuses on enhancing the drag reduction (DR) phenomenon within a rotating disk apparatus (RDA) using polymer-surfactant additives. The complex mixture of polyisobutylene (PIB) and sodium dioctyl sulfosuccinate (SDS) was used. These materials were tested individually and as a complex mixture in RDA at various concentrations and rotational speeds (rpm). The morphology of this complex was investigated using transmission electronic microscopy (TEM). The reduction of the degradation level caused by the continuous circulation of surfactant additives in RDA could improve the long-term DR level. Experimental result shows that the maximum %DR of the complex mixture was 21.455% at 3000 rpm, while the PIB and SDS were 19.197% and 8.03%, respectively. Therefore, the complex mixture had better performance than these substances alone and were highly dependent on the alkyl chain of the surfactant.

An Overview on Most Effective DRAs in Crude Oil Pipelines

“…This will lead to higher costs. Musaabet al [45] studied the drag reduction efficacy of Sodium Di-octylsulfosuccinate (SDS), Sodium dodecyl benzene sulfate (SDBS), and Sodium lauryl ether sulfate (SLES) with diesel fuel in a rotating disk apparatus is investigated, the result showed that the maximum drag reduction achieved was 29.5% for Sodium lauryl ether sulfate (SLES) at 1100 RPM and 1000 ppm.…”

Control of Both Ionic Properties and Micellar Structure for Enhanced Turbulent Drag Reduction Performance of Surfactant Solutions

“…27 This new drag reducer features a low molecular weight, a fastdissolving rate, and low interfacial tension, and the SPR DR rate calculated by the Fanning friction coefficient exceeded 60%. Rashed et al 28 used a complex mixture of polyisobutylene, and sodium dioctyl sulfosuccinate (SDS) was used to enhance the DR phenomenon. Abdulbari et al 29 also found that the addition of a tiny amount of surfactant to the polymer system resulted in a significant improvement compared to the pure polymer DR.…”

Drag Reduction Performance and Stability of an Organic Polymer, Surfactant, and Their Complexes

“…The presence of polymeric DRAs in the transported solutions is in the form of networks and clusters depending on the polymer solubility and the polarity. The molecular weight, polarity, and morphology of the DRA polymer will control the size, shape, and distribution of these clusters in the fluid core and on the conduit's solid surface [15,16]. It is believed that the characteristics of these clusters strongly control the drag reduction phenomena and stability of the polymeric DRAs.…”
