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.

摘要： 利用演化法对某炼厂多杂质氢网络进行优化。在考虑源阱之间的各种匹配可能和氢源之间的互补可能基础上，依次求取最大匹配流量矩阵（M矩阵）、潜在匹配流量矩阵（P矩阵）和最优匹配流量矩阵（O矩阵），确定系统的最小公用工程消耗量为1495.83 m³·h^-1，其节约量为1004.17 m³·h^-1，占现行新氢消耗量的40.2%。此外，根据O矩阵确定了相应的最优氢分配网络。
