武汉—信阳成品油管道顺序输送优化运行分析

Optimization of Sequential Transport Operation of Wuhan—Xinyang Oil Products Pipeline

为确保武信成品油管道顺序运行更加优化,现依据成品油管道水力特性和顺序输送理论,对武信管道临界雷诺数、临界流量、各站混油量、初始混油长度、批次输送量等管路运行数据进行计算和分析。结果表明:临界雷诺数Rec=45 590,临界流量Qc=228 m3/h;常见工况下,理论计算出信阳末站混油长度I=932.6m,混油体积V=70.9m3,与实际混油下载量较为接近;当初始混油长度C0≤150m时,首站产生的初始混油量对末站总混油量的影响较小;汽油终馏点对批次输送量影响较大,批次输送量应根据首站注入油品质量作适当调整。

To ensure the sequential transport operation of Wuhan-Xinyang oil products pipeline more optimized,on the basis of oil products pipeline hydraulic characteristics and sequential transport theory,the pipeline operation data,such as critical Reynolds number,critical flow,the mixed oil quantity,initial oil mixing length,batch throughput,were calculated and analyzed.The results show that the critical Reynolds number(Rec) is 45590,the critical flow rate(Qc) is 228 m3/h;under the common conditions,the calculated the oil mixing length(I) in terminal station at Xinyang is 932.6 m,and the mixed oil volume(V) is 70.9 m3,which are close to the actual quantity of oils downloaded;when the initial oil mixing length CO ≤ 150 m,the initial mixed oil quantity formed in the first station has small impact on the total mixed oil quantity;gasoline end point affects greatly the batch throughput,which should be adjusted according to the quality of oil products injected into the first station.
