Drag reducing agents (DRA) and flow improvers for the hydraulic optimization of oil pipelines, multiple pipelines, water injection system and flow lines.
Drag reducers also known as grad reducing agents (DRA) and flow improvers, are any material that reduces frictional pressure loss during fluid flow in a conduit or pipeline. Pressure loss reduction is achieved by reducing the level of turbulent motion in the flow . Using DRA allows increased flow using the same amount of energy or decreased pressure drop for the same flow rate of fluid in pipelines. Flow improvers have proven to be effective in various gravities or oil or even in multiphase derivates that include: Western Canada Select, Castilla, Merey, SJVH, petrozuata, gasoline, diesel among otrhers. These can offer more than 50 percent friction reduction in pipelines operating in turbulent flow conditions.
