From the above analysis and Table 9, it can be concluded that after adding drag
reducer in Dali-Baoshan section, the pipeline transport income can be increased by
about 2.74 million yuan in half a year regardless of the initial investment. For each
year following, the annual revenue of pipeline transportation will increase by about 6.68
million yuan.
6 Conclusion
In this study, hydraulic characteristics of oil product pipeline in Dali-Baoshan section are
analyzed, and parameters of equipment in Dali Station were calibrated. Dali-Baoshan
section is found to be qualified to the requirements of adding drag reducer to enhance
throughput. Then through field tests, it has been proved that the throughput of DaliBaoshan section can be increased to 115 m 3 /h, and there is still surplus ability for
pressure-bearing of equipment and pipeline in Dali Station. Afterwards, by means of
evaluating economic benefits of increasing throughput, we can find that pipeline income
can be increased of about 6.68 million yuan each year with drag reducer added.
