“…The cryogenic process has moderate purity (90e95%) with high recovery (90e95%) (Peramanu, Cox, & Pruden, 1999). Compared with the PSA process, a polymeric membrane system has no moving parts and is extremely reliable, although it is of lower purity.…”

“…These studies normally emphasize the purifiers' design and/or provide mathematical models of purifiers in hydrogen networks. Peramanu et al [15] evaluated the economic performance of different purification processes for off-gases. Liao et al developed a systematic approach that provides more network structure possibilities for the placement of compressors and purifiers [10].…”

For optimization of a hydrogen network, a steam reformer is associated to the feedstock and linear programming (LP) is applied. The investigated network consists of one steam reformer and two feedstocks. By exerting LP and the mentioned association, total annual cost decreasing is achieved in a case study in which natural gas and off-gas were considered as feedstocks. The optimization problems of the hydrogen network comprise the hydrogen network retrofit design and the feedstock selection with respect to their cost. Nonlinear programming (NLP) and mixed-integer nonlinear programming (MINLP) models are developed for optimization based on a two-case study: for the first one, an existent optimization method on hydrogen networks is investigated and for the second one, revision of a recent optimization method on hydrogen networks associated by an LP model in the steam reformer unit is applied. These two cases resulted in total annual cost reductions of 34 % and 45.9 %, respectively.

“…Hydrogen purification processes are compared in Table 1. PSA, getters, and cryogenic distillation processes are commercially available processes, but they are energy-intensive and complicated [1][2][3][4]. Membrane-related processes are promising technologies for the production of high-purity hydrogen.…”

A hydrogen purifier equipped with Pd-Cu-Ni/PNS membranes has been developed to purify low-grade hydrogen and supply it to processes requiring high-purity hydrogen. The purifier does not include any purge system to flush out hydrogen from the membrane module to prevent membrane embrittlement because there is no α-β phase transition below the critical point of the Pd-H system, making the purifier simple. The hydrogen purifier was tested with three different grades of hydrogen, 90, 99 and 99.9%, to determine the effects of the grade of feed hydrogen on the hydrogen permeation behavior. A lower grade required a lower recovery ratio of the purifier to obtain a given relative hydrogen permeation flux. It was confirmed that the purifier can provide high-purity hydrogen to a gas chromatograph (GC) for carrier and make-up gases. A 75-day durability test provided evidence that the hydrogen purifier could be useful for extended periods as needed for commercial processes.
