三角图示法优化具有温度和压力约束的氢网络

Ternary diagram approach for the optimization of hydrogen network with pressure and temperature constraints

本文提出利用三角图示法优化合成具有温度和压力约束的氢网络。该方法将氢浓度,温度和压力约束看作氢网络匹配问题的3种关键性质,通过性质聚类转换,利用三角图示法实现氢源和氢阱的匹配。源存在域的概念的引入及表征,有助于实现源阱匹配及流量目标值的确定。不考虑增加压缩机和换热器的氢网络优化改造实例分析显示了该方法的可行性和实用性。

The ternary diagram approach is utilized to target and design the hydrogen network with pressure and temperature constraints. Hydrogen purity, temperature and pressure are considered as three kinds of properties. The property values are then transferred to be cluster values, which are described on the ternary diagram. The introduction of available region for sources is useful for the determination of source-sink matching. The feasibility and applicability of the proposed approach is illustrated by the synthesis of hydrogen network without the consideration of adding compressors and heat exchangers.
