Abstract: The evolutionary method is applied to optimize the hydrogen network with multiple impurities. With every match possibility and the complementary advantage of source streams considered,the maximum match flow rate matrix(M matrix),potential match flow rate matrix(P matrix),and optimal match flow rate matrix(O matrix) are determined in turn.The results shows that the minimum hydrogen utility consumption of this system is 1495.83 m³·h^-1.Compared with the current hydrogen utility consumption,the saving potential is 1004.17 m³·h^-1，accounting for 40.2% of the utility consumption. Furthermore,the optimal network is determined according to the O matrix.
