Abstract:
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 17.079×103 Nm3/h to 14.125×103 Nm3/h and a higher hydrogen saving, 17.29%, is achieved. These verify the feasibility and applicability of the proposed approach in this work.
