Drag force reduction of flowing crude oil by polymers addition

الملخص EN

Studying of effect polymers addition on drag force for flowing crude oil are presented.

Two types of Iraqi crude oil have been studied namely, Karkok crude oil with API = 35.8 and Basrah crude oil with API = 31.2 .

Three types of linear polymers (poly isobutylene PIB150K, PIB90K and poly isoprene PIP) are used, the polymers are injected through pumping system at different concentrations rounded between (10-50) ppm with temperatures range of 30o to 50oC.

Several experiments were carried out to determine the best concentration of polymer which is satisfied lowest drag force on of crude oil flow rate .The results show that the best execution are realization for PIB150K at 30 ppm and 45oC for two types of crude oil.
