中文摘要：
利用三角图示法确定具有多杂质约束的氢气分配网络的目标值并提出相应的网络设计步骤。引入了层次分析法,用以确定具有多杂质约束条件下氢源的选用次序和氢阱的匹配次序。案例分析中,首先调整浓度数据的数量级,无因次化并重新归一化,进而可以在三角图中合理表征源的存在域、阱的可行域;然后进行源阱的匹配,可以确定出可行解域,从而获得氢源氢阱的匹配网络,同时考虑压缩机的配置,可确定最终优化的氢气分配网络。经过优化之后,氢公用工程用量由17.079×10^3 Nm3/h减少为14.125×103 Nm3/h,节氢率达到17.29%。案例分析结果验证了该方法的可行性。
英文摘要：
This paper presents a ternary diagram approach to determine target and design hydrogen distribution network with multiple impurities. Moreover, the analytic hierarchy process is further introduced to determine the selection sequence of hydrogen sources and matching sequence of hydrogen sinks. In the case study, the concentration data are adjusted to the same order of magnitude and the dimensionless data in order to determine the available region for hydrogen sources and feasible region for hydrogen sinks in the ternary diagram. Thus, the feasible solution region for each hydrogen sink can be obtained by means of the cross section of feasible region and available region. With the appropriate implementation of compressors, the final optimal hydrogen distribution network is synthesized. The stream flow rate from the hydrogen plant is reduced from 17.079×10^3 Nm3/h Nma/h to 14.25×10^3 Nm3/h and a higher hydrogen saving, 17.29%, is achieved. These verify the feasibility and applicability of the proposed approach in this work.
