1 Introduction 1.1 Relevance and Motivation In the last years, the need for alternatives to fossil fuel has been explored due to environmental concerns. In order to be significant, an alternative fuel has to be technically feasible, economically competitive, environmentally satisfactory and readily accessible. Plenty potential alternative fuels have been suggested, comprising methanol, ethanol, hydrogen, biodiesel, natural gas, liquefied petroleum gas (LPG), Fischer-Tropsch fuel p-series, solar fuels, electricity (Meher LC et al. ,2006) [1]. Lately, hydrogen has been extensively explored as an alternative source of energy due to its features. Hydrogen is the most abundant element in the universe, it has a higher specific energy content, when compared with the other fuels and, is widely used in numerous chemical process industries as hydrocracking, hydrogenation of fats and oils, methanol production, manufacture of silicon, among others [2]. This component can be obtained in the course of several chemical and industrial processes by the conversion of hydrocarbons and methanol on a reforming process to produce a synthesis gas [3]. Despite all the methods for obtaining hydrogen, catalytic reforming of natural gas bound with a water gas shift reaction step is mainly the utmost profitable process for hydrogen production at a commercial scale [4]. In this process, hydrogen is obtained mixed with a high proportion of impurities, such as water vapour, carbon dioxide, methane, carbon monoxide, and in some cases, nitrogen. Hydrogen is also obtained mixed with impurities in off-gases from many processes, such as catalytic reforming of naphta, ethylene production, and ammonia production. Reducing the content of impurities in hydrogen is essential for its applications [5]. 1.2 Process System Enterprise Process System Enterprise is the world’s leading supplier of Advanced Process Modelling technology and related model-based engineering and innovation services to the process industries.
