Drag Reducing Agent
A Drag Reducing Agent (DRA), alternatively known as a Flow Improver or Pipeline Booster, can dramatically increase your pipleline flow rate or be used as a drag reducer to decrease friction in the pipeline, reducing energy costs.
DRA is essentially an anti-turbulent polymer chemical that when injected into a pipeline (where the fluid is turbulent) can modify the flow behaviour by reducing the frictional pressure drop along the pipeline length (acting as a Drag Reducer) or where capacity permits, can serve as a pipeline booster.
Essentially it acts as a flow improver to pipelines that have the capacity to provide an increase in flow (using the same amount of energy) resulting in a much higher throughput, or alternatively where the pipeline is already at maximum capacity, it can maintain the same flow rate whilst using considerably less energy.

How does it work
The active ingredient the Drag Reducing Agent is an ultra-high molecular weight linear poly-alpha-olefin. When DRA dissolves into the pipeline, the polymer molecules begin to uncoil and outspread as they interact with the pipeline flow. This interaction is complex; the long chain molecules dampen turbulent bursts near the pipe wall as if they were acting as tiny shock buffers.
DRA is usually injected into a pipeline just at the discharge side of the mainline pump, where a positive displacement pump capable of surpassing the line pressure is used to inject DRA into the pipeline. It will only work in turbulent flow regimes; they do not coat the pipeline wall, modify the fluid viscosity or have any chemical reaction with the oil.
