Drag Reducing Agents
Drag reducers – also known as Drag Reducing Agents, DRAs and Flow Improvers -- are any material that reduces frictional pressure during fluid flow in a conduit or pipeline. Using DRAs allows increased flow using the same amount of energy or decreased pressure drop for the same flow rate of fluid in pipelines. The current class of DRAs, such as ConocoPhillips’ Specialty Products (CSPI) range of LiquidPower™ Flow Improver products, consist of long-chain hydrocarbon polymers that act as buffers along the pipe wall to decrease the amount of energy lost in turbulent formation.. Nalco and CSPI work together to identify applications of DRA in select regions of the world.
