TRANSCRIPT
Drag Reducer AdditiveQUICKFLOW . .
HISTORY
• Discovery– University– Military
• Commercial Applications– 1979: Alaska: Eliminate Station– 1993: Ecuador 408,000 BPD
Technology Envolved
• Refined Fuels Transportation• High Efficiency Products • It is a Tool
Objectives For Today
• Understanding Role Of QUICKFLOW • Understanding Role Of Quickflow Products• Optimization Of Application
Fundamental Of DR
• Microscopic Level
• Macroscopic Level
Microscopic Level
– Inhibits Propagation Of Turbulence near Wall
QUICKFLOW Products
Important Factors
• Viscosity• Dissolution• Polymer Degradation
• Reduces Pressure Losses• Same Quickflow rate Produces Less Friction• Lowers Discharge/Increases Suction• Comparison Of Changes Is DR
