... injection at PS#1 was tested. With an average DRA injection concentration of about 23.4 ppm, 8.28% of drag reduction and 5.09% of throughput increase was gained. It is indicated that 70-80% of drag reduction capacity was still remained after 237 kilometers of pipe wall shear from PS#1 to PS#2. But after...
