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
