A Review of Drag-Reducing Agents (DRAs) in Petroleum Industry

Drag-reducing agents (DRAs) are usually added to the fluid to reduce the drag and improve the flowing capacity or pumping rates of the fluid required for achieving the targeted flow rate or enhancing transportation efficiency.

A Review of Drag-Reducing Agents (DRAs) in Petroleum Industry - Springer

The requirement of an oil?eld system dictates the basic characteristics of the DRA, such as polymer DRA, can be used for transportation of oil and gas; however, the surfactant is preferable for other systems such as drilling and fracturing applications.

Drag reducing agent - OilfieldWiki

A drag reducing agent (DRA), also called drag reducer or flow improver, is a long chain polymer chemical that is used in crude oil, refined products or non- potable water pipelines. It is injected in small amounts (parts per million) and is used to reduce the frictional pressure drop along the pipeline's length.

Drag reduction in single-phase crude oil flow: A mini-review

Drag-reducing agents Crude oil 1. Introduction The transfer of crude oil by pipeline is very important to the world economy. In recent decades, the high growth in global crude oil consumption has posed problems for oil transportation due to the increase in energy loss from turbulent flows.

The effect of polyacrylamide drag reducing agent on friction factor and

As shown in Table 1, the study of the effect of drag-reducing agents on the heat transfer performance of the system has been very limited. among these studies, we can refer to the study of Zhang et al. [25] which reported that using PAM as a DRA reduced the friction factor and heat transfer coefficient by about 37% and 70%, respectively.

Drag reducing agent

Drag-reducing agents (DRA), or drag-reducing polymers (DRP's), are additives in pipelines that reduce turbulence in a pipe. Usually used in petroleum pipelines, they increase the pipeline capacity by reducing turbulency and increasing laminar flow. [1] Description

Experimental study on optimum concentration of polyacrylamide for drag

The effects of adding polyacrylamide (PAM) to pure water on pressure drop and heat transfer in a compact heat exchanger was experimentally investigated. Laminar flow was studied to transfer heat between water and air. By adding PAM to water, the pressure drop has continuously decreased until the concentrations of 100 ppm. After this optimum concentration, the pressure drop began to increase
