In this paper, the improved problem table (IPT) is referred to locate the flowrate targets of interplant hydrogen conservation network. Firstly, the flowrate targets for individual hydrogen networks are located and the purge gas streams can be identified via IPT. Next, the IPT is utilized to determine the flowrate targets for the overall interplant hydrogen network. The arising problems with multiple resources and purge gas streams can be coped with by IPT. One example is solved to show the effectiveness and applicability of the proposed approach. The results show that the flowrate of hydrogen utility (0.01) for Plant B is reduced by 1,784 Nm3/h and the hydrogen utility (0.05) for Plant A is totally conserved.
