中文摘要:
      根据影响管径设计的因素,从质量流量、管长和压降3个方面对Rubin管道设计模型进行分析,根据分析结果建立相应的数值模型;使用MIT管道设计模型验证所建数值模型的可靠性;在此基础上从管道总资本成本和中间加压站成本两方面分析管道经济成本.研究结果表明,模型各变量的变化规律及相应数值模型类型均与验证模型相同,且有很好的相关性(其决定系数R2均大于0.970).
英文摘要:
      According to the factors affecting the diameter size (i.e. mass flow rate, pipeline length and pressure drop), this article analyzed the pipeline design model of Rubin from the three aspects and established their corresponding numerical models. Furthermore, the reliabilities of the proposed numerical models were validated by another pipeline design model (i.e. the MIT model). Besides, the economic cost of CO2 pipeline transportation was also estimated through the cost analysis of the total pipeline capital investment and the additional pressure station cost. The research result shows that: (i) the proposed models share the same variable change rules and numerical model types with the validation model, and (ii) all of them have high correlation with numerical models (their correlation coefficients R2 are larger than 0.970). The pipeline design and cost analysis proposed in this work have some reference value for the process design of CO2 pipeline transportation.
