Drag reduction in turbulent crude oil pipelines using a new chemical solvent

Pilot-scale experiments have been conducted to reduce drag in pipelines carrying crude oil using a new chemical additive. The effects of pipe diameter and crude oil flow rate on drag reduction rate have been studied in 1″, 2″, 3″, and 4″ pipes. The effect of additive concentration on drag reduction...

Zusammenfassung:	Pilot-scale experiments have been conducted to reduce drag in pipelines carrying crude oil using a new chemical additive. The effects of pipe diameter and crude oil flow rate on drag reduction rate have been studied in 1″, 2″, 3″, and 4″ pipes. The effect of additive concentration on drag reduction was also investigated, and it was found that a 9-ppm concentration of the chemical solvent is optimum for the studied system. A maximum drag reduction of 63% has been achieved when 9 ppm of the solvent was added to the 4″ pipe.
