... Abstract Drag Reducing Agents (DRAs) are commonly used to reduce the frictional pressure loss under turbulent flow conditions. This reduction can potentially lead to a meaningful increase in pipeline production capacity. In the last 20 years, the continuing and growing demand of energy...

... ABSTRACT: Drag Reducer Agent (DRA) is a flow improver that is used to optimize the pipeline capacity by reducing drag and hence lowers the pressure drop across the pipeline. The great benefits of using (DRA) are increasing the pipeline flow rate while maintaining current pipeline pressure...
