Agitator tank device and drag reduction agent evaluation
The device that consists of tank and disk agitator for evaluation drag reduction agents (DRA) was established. The effect of DRA was defined by testing the changes of agitator torque that drives the disk rotation. The HG-DRA for oil pipeline from Linyi to Puyang was studied by agitator tank device. The relationships between the drag reduction rate and Reynolds number, concentration,balance time were studied. The best concentration and the highest Renords number for the best drag reduction rate were confirmed.The results show that the drag reduction rate tested in agitator tank is close to that in pipeline. The maximum error of drag reduction rate between pipeline and agitator tank is 18.3%, which indicates that the agitator tank device is available to evaluate the effect of DRA for pipeline and it also has the advantages of simple, easy to be operated and using small volume of oil. Those are very helpful for operaters to know the properties of DRA and operate pipeline well.
