摘要/Abstract

摘要： 提出一种具有净化单元氢网络的迭代设计方法。首先假设净化后源物流的量足够大,将之看作系统的新增源物流即可构成具有净化单元的初始氢网络。运用多氢源匹配方法来设计氢网络,从而得到净化后源物流的用量F_reg和所有未回用的内部源物流合并计算出的净化后源物流的量F_reg^total。比较F_reg和F_reg^total的大小,当F_reg^total<F_reg时,将F_reg^total作为下一次迭代净化后源物流的量的初值,只需几次迭代即可得到最终设计;当F_reg^total≥F_reg时,将F_reg的值作为最终设计的净化后源物流的用量,按照由F_reg值确定出的净化前源物流的量选取杂质浓度较低的未回用的内部源物流用于净化,对此种情况,不需后续迭代即可得到最终设计。对文献中几个实例的研究表明,该方法设计步骤简单可行,不仅能得到氢消耗目标值,而且还能得到氢网络的具体设计。

Abstract: An iterative method for designing hydrogen networks with purification units is presented.First, the purified source flow rate is assumed to be large enough, regarding the purified source as a new source.And then, the initial hydrogen network with purification units is constituted.By using the source matching method, the hydrogen network is designed, the purified source amount F_reg that can be used and the purified source amount F_reg^total from purifying all internal sources that have not been reused are obtained.When F_reg^total<F_reg,F_reg^total is regarded as the initial value of the purified source in the next iteration, and the final design is obtained by only a few iterations.When F_reg^total≥F_reg,F_reg is used as the value of the purified source of the final design, and the internal source with the lowest impurity concentration that has not been reused for purification is selected.In the latter case, the final design is obtained without further iterations.By examining some examples reported in literatures, it is found that the method are simple and effective, moreover, not only the hydrogen consumption target value but also the specific design of hydrogen network can be obtained by using this method.
