ABSTRACT Predicting the efficiency of a DRA is still dependent on the use of models developed through field tests. Two forms...

... increased to 177,000 BOPD when Maximum Allowable Working Pressure (MAWP) reduced from 1463 psi to 950 psi. This paper shows how to increase flow rates without reaching MAWP, two methods are recommended: loop the existing pipeline using a 406.4 mm x 56 km pipe. Use a drag reducing agent (DRA) to reduce...

... ABSTRACT One of the methods currently used to increase pipeline transfer capacity, when the option of extra loops or pumping stations is unavailable, is the use of the drag-reducing agents (DRA). DRA are long-chain polymeric compounds that reduce turbulent frictional losses. Nowadays...

... reducing agents (DRAs), electric power and other fuels. These tradeoffs are difficult to analyze because of the effects of electric power rate structure and various operational constraints. This paper will discuss these tradeoffs and present a case study to show the cost savings achieved...

... the mechanism behind a possible drag reduction. Published field tests have shown that drag reducing additives (DRA) and corrosion inhibitors may have an effect on the pressure loss in gas pipelines. This has basically been explained by a smoothening of the pipeline wall surface when additives deposit...

... ABSTRACT Use of Drag Reducing Agents (DRA) in a liquids pipelines can increase throughput and / or reduce operating costs, both of which can have a significant impact on the revenue and profit of the pipeline company. The decision to use DRA is often based on a short-term test in one segment...
