抚锦成品油管道不同注入方案比选

Comparison of injection schemes for Fushun-Jinzhou Oil Products Pipeline

抚锦管道各石化厂注入抚锦成品油管道油品的柴汽比差别较大,且部分种类油品中间无注入。基于此,设计了不同注入方案,并进行了比选。结果表明:在辽阳首站出站流量恒定或辽河注入泵站出站流量恒定的情况下,辽河-锦州段或辽阳-辽河段流量波动太大,最大流量约为最小流量的3倍,管道利用率较低,不利于辽河或辽阳站输油泵配置方案的选择;当辽阳出站流量和辽河出站流量均有波动时,其注入方案可降低全线流量的波动范围,提高管道的利用率,降低工程投资。综合比较工程投资和运行费用,并结合目前国内管道设计压力及设备现状确定管道的设计参数,最终确定辽阳和辽河站均以变流量作为抚锦成品油管道的注入方案。

The oil products injected into the Fushun-Jinzhou Refined Oil Products Pipeline from relevant petrochemical plants vary greatly in diesel-gasoline ratio, and some oil products are not injected at certain parts of the pipeline. In this regard, different injection schemes are designed and compared. The results show that, when the outlet flowrate of Liaoyang Initial Pump Station and Liaohe Injection Pump Station is constant, large flowrate fluctuation occurs in Liaohe-Jinzhou pipeline section or Liaoyang-Liaohe pipeline section, the maximum flowrate is approximately three times of the minimum flowrate, and the pipeline utilization is low, which are not conducive to the configuration of pump sets at the stations; when the outlet flowrate of Liaoyang and Liaohe stations both fluctuate, the injection scheme can reduce the fluctuation range of the whole line flowrate to improve the pipeline utilization and reduce the project investment. The project investment and operating costs are comprehensively compared, and the pipeline design parameters are determined considering the designed pressure and equipment available. Finally, variable flowrate is determined as the injection scheme of Liaoyang Pump Station and Liaohe Pupm Station to Fushun-Jinzhou Refined Oil Products Pipeline.
