Frictional pressure drop (or frictional resistance) reduces the flow rate of the fluid in the pipeline, resulting in a decrease in pipeline delivery and an increase in energy consumption. Injecting a small amount of polymer in the fluid can reduce the flow resistance in the state of rheological flow. This phenomenon is called polymer drag reduction. The chemical agent used to reduce the resistance to fluid flow is called drag reducing agent (DRA).
The concept of drag reduction was introduced in the 1940s, and drag reducing agents were used in crude oil and refined oil pipelines in the early 1980s to improve pipeline output and reduce pipeline pressure, conveniently and safely with very low amount of additives.
Significantly increase delivery volume without increasing delivery pressure on existing pipelines.
Significantly reduce upfront investment and continuing operating cost on new pipelines design and construction.
Suitable for pipelines in harsh environments by increasing transmission efficiency and reducing the required number of pumping stations.
