Based on the existing selection of the oil pump in Dali Delivery Station with pump,
maximum gasoline throughput in Dali-Baoshan section is 134 m 3 /h, which is equivalent to the maximum diesel transmission with drag reducer added. Therefore, it is not
necessary to consider utilizing drag reducer and increasing gasoline throughput.
It can be seen from the above analysis that the flow between Dali Station and Baoshan
Station can be increased to 125 m 3 /h with the injection of drag reducer.
4 Field Test
Drag reducer produced by Baker Hughes has been applied to conduct the drag reducing
test during the transportation of diesel in Dali-Baoshan Section. The dosing rate applied
in the test is 5 ppm. The hydraulic gradient diagram is shown in the figure below.
It can be seen from Fig. 7 that after adding drag reducer at the concentration of
5 ppm, the flow rate in Dali-Baoshan section can be increased to 115 m 3 /h, and there is
still a large amount of pressure in the equipment and pipeline of Dali Station.
5 Economic Analysis
Table 9 shows the comparison of economy before and after increasing throughput in
Dali-Baoshan section.
(1) Through inquiring about the price from manufacturers, a set of skid-mounted drag
reducer about 500,000 yuan.
(2) Through inquiring about the price from manufacturers, the price of drag reducer is
113,160 yuan per barrel (the volume of which is 984 L). Drag reducer adopted
is from the same manufacturer as Lanzhou-Chengdu-Chongqing Oil Products
Pipeline and bulk purchase is available.
